<h1>FireBug --- GPS Driver</h1>
! <p> FireBug uses the <tt>gps</tt> driver to interface with a GPS receiver
! and handle location information. </p>
<h2>Introduction</h2>
! <p> The current driver implements standard NMEA protocol to interact
! with an AXIOM GPS receiver. Running <tt>gpsM.nc</tt> on
! the client mote initializes the receiver for GPS Fix Data (GGA)
! reception. Incoming GGA data is checked by the client for validity,
! parsed, and then stored in its EEPROM flash memory. </p>
! <h2>How <tt>gps</tt> works</h2>
! <p> GPS receivers provide location and time information in a variety
! of data formats. At initialization, the client's UART is
! set to the same baud rate as the GPS receiver. Next, <tt>clearGPS()</tt>
! is called, which commands the receiver to block all output.
! The receiver requires several seconds before it can start processing
! NMEA commands following power on. For this reason, the first command
! in <tt>clearGPS()</tt> is sent 100 times until the receiver has
! warmed up.</p>
! <p>For this application, a single GGA message is required. To acquire this,
! <tt>getGPS()</tt> is called, which requests GGA data at 1 Hz.
! The number of satellites used in constructing each GGA message
! is then determined. When this number exceeds three, the corresponding
! message is parsed and stored in the client's EEPROM.</p>
! <p> Values stored in the client's memory can the be retrieved and broadcasted
! over the radio at any time with <tt>GenericBase</tt>. Instructions
! on this are given at the end of this guide. </p>
! <h2>Sending Commands to the Receiver</h2>
! <p> Communication between the client and receiver is handled by <tt>
! gpsM.nc</tt>. After the client's second UART
! (UART1) is set to 4800 baud, NMEA commands may be sent to the
! gps receiver. For SiRF chips, these generally have the form:</p>
! <center>
! <p>$PSRF,103,<b>Message type</b>,00,<b>Rate</b>,01,*<b>Checksum</b></p>
! </center>
! <p>followed by a carriage return ('\r') and linefeed ('\n'). There are six
! message types: </p>
! <center>
! <p>GGA=00, GLL=01, GSA=02, GSV=03, RMC=04, VTG=05</p>
! </center>
! <p> To block output of a certain message type, set Rate = 00. Rate = 01 corresponds
! to a 1 Hz output. Finally, the checksum is computed by performing an XOR
! on all characters, including the comma delimiters, between $ and *. Each
! character of the above string is contained as an element in the array <tt>
! cmd_msg</tt>, which is used throughout <tt>gpsM.nc</tt>. By changing
! array entries, different commands can be sent to the receiver, as shown
! below:</p>
! <center>
! <table class="code">
! <tbody>

<h1>FireBug --- GPS Driver</h1>
! <p>FireBug uses the <tt>gps</tt> driver to interface with a GPS
! receiver and handle location information.</p>
!
<h2>Introduction</h2>
! <p>The current driver implements standard NMEA protocol to interact
! with an Leadtek GPS receiver. The incoming GPS data stream is
! filtered for GGA messages, which are compressed into an 11-byte
! character array and stored in the host's EEPROM memory.</p>
!
! <h2>Receiving a GGA Message</h2>
! <p>GPS receivers provide location and time information in a variety
! of data formats. For this application, the GGA message contains
! all the necessary time and geographic information and hence is the
! only one used. Each GPS message starts with <tt>$GP</tt> followed
! by the message identifier (MID). Data streaming in from the receiver
! is continuously monitored so that when the MID sequence for GGA is
! received, the preceding message is stored in a buffer, <tt>gga_string
! </tt>.</p>
!
! <center>
! <table class="code">
! <tbody>
! <tr>
! <td width="100%">
! <pre>
! event TOS_MsgPtr GpsReceive.receive(TOS_MsgPtr data) {<br> int8_t gga_string[MSG_LENGTH];<br> bool gga_read = FALSE;<br> bool gga_read_done = FALSE;<br> uint16_t i = 0;<br> uint8_t j = 0;<br> <br> GPS_MsgPtr gps_data = (GPS_MsgPtr)data;<br> <br> while (!gga_read_done) {<br> <br> if(gps_data->data[i] == 'G') {<br> if(gps_data->data[i+1] == 'G') {<br> if(gps_data->data[i+2] == 'A') {<br> gga_read = TRUE;<br> }<br> }<br> }<br> ...<br> if(gga_read) {<br> gga_string[j] = gps_data->data[i];<br> j++;<br> }<br> <br> i++;<br> }<br> }
! </pre>
! </td>
! </tr>
! </tbody>
! </table>
! </center>
!
! <p>Recording is completed with arrival of the termination byte,
! <tt>*</tt>. <tt>gga_string</tt>, is then sent to <tt>parseGGA</tt>,
! where it is broken into an array of character strings for log entry.
!
! <center>

!
! <h2>Storing GGA data</h2>
! <p>In <tt>parseGGA</tt>, the comma-delimited fields of <tt>gga_string
! </tt> are placed into an array, <tt>write</tt>, which is then sent to
! <tt>logGPS</tt> for storage.</p>
!
! <p>The process for compressing field information to one or two bytes
! is described below. First, a pointer to a <tt>GGA_Msg</tt> is set.
! A <tt>GGA_Msg</tt> has the following data structure:</p>
!
! <center>
! <table class="code">
! <tbody>
! <tr>
! <td width="100%">
! <b>gps.h</b>

! typedef struct GGA_Msg<br> {<br> uint8_t hours;<br> uint8_t minutes;<br> uint16_t dec_sec;<br> uint8_t Lat_deg;<br> uint16_t Lat_dec_min;<br> uint8_t Long_deg;<br> uint16_t Long_dec_min;<br> uint8_t NSEWind;<br> } GGA_Msg;
! </pre>
! </td>
! </tr>
! </tbody>
! </table>
! </center>
!
! <p>The entry <tt>write[i][j]</tt> represents the ith character in the
! jth field of GGA string. Fields of interest, their field number, and
! the number of characters they contain, including decimal points, are
! given in the table below:</p>

Measurements were done on a clear morning in a sparsely wooded suburban environment. </p> <p> For raw data, click <a href="cold_start.htm">here</a>. The average cold-start time from 22 samples taken in various locations was between 51 and 52 seconds. Moreover, the following observations were made: <ul> <li> Cold-start acquisition time seems to be unrelated to the # of satellites in line of sight. </li> <li> Geographical data more accurate with four or more satellites. </li> <li> As observed at 'Main Stacks' and 'Under Trees', GPS occasionally fails even if an adequate number of satellites is know to be in line of sight. </li> <li> Small tree canopies do not block GPS signals. </li> <li> Acquisition times might be reduced by setting the receiver's sampling rate rather than power cycling it from the host (mote). To test this, though, it will be necessary to send commands to the receiver. </li> </ul> <h2> Location Accuracy </h2> <p> When the number of satellites is greater than three, the GPS estimatation was reliably within ten meters of the true location. In this regard, the Leadtek performed similar to other receivers of the same class. </p> <h2> Movement Tracking </h2> <p> Lastly, a brief experiment was done to determine how well the receiver could track movement beyond the ten meter error. In particular, the GeoMapper software was used to see whether the GPS could follow a walk around Memorial Glade without lag. (Note: no pauses were taken during walks.) </p> <p> For a leisurely four minute walk, no lag was apparent. For a more brisk walk, a lag of about 2-3 seconds was seen. The GPS refresh rate was set at 1 Hz (note: blue markers in figure correspond to spots where a new GPS fix was gotten during the walk). </p> <center> <img src="./images/mem_glad.jpg" alt= "Motion Tracking about Memorial Glade"> </center> <hr /> <p> Last Updated: $Date: 2003/07/28 16:47:45 $ by $Author: csm23 $. </p> </body> </html> |

! \paragraph{Mehta and El Zarki}~\cite{mehta:v2002} propose
! a scatternet tree structured network for fixed wireless
! sensor area networks for structural health monitoring
! of bridges, highways and other infrastructure. The algortihm
! allows arbitrary placement of nodes, and does not require
! nodes to be in radio proximity of every other node.
!
! The ``scatternet'' tree is rooted at a network hub, which
! executes most of the scatternet algorithm to build routes for
! each sensor. The algorithm has two phases: discovery and
! connection. During discovery, each node reports all other
! nodes in radio proximity to the hub, which creates a
! neighborhood matrix. The nodes are ``backtracked'' recursively
! using a depth-first search, starting at the hub and passing
! to each node in turn.
! The connection phase is performed by the hub. The tree is
! built using a breadth-first search with statistics such
! as link strength, load factor, and degree, collected during
! discovery phase.
!
!
! The complexity of building the tree increases
! exponentially with the number of nodes, which the authors
! tackle using a simulated annealing (SA) approach.
! The objective function is chosen to minimize the
! load variation across nodes in the subtrees, and
! an energy formulation for this is presented. The
! authors provide a detailed discussion of the SA.
! Results from a simulation implementing the proposed
! method indicate that adaptive methods work better
! for minimizing interference in the resulting
! network.

\section{Multihop routing}
!
! \blast\ is a routing stack of wireless ad-hoc
! networks for mote sensing application. Sensor
! readings are collected and encapsulated by the
! applications, blast will establish a self
! organizing network among the nodes,and route
! the packet to the basestation. All nodes in the
! network broadcast route messages, so every mode
! can choose parent node based on the link reliability
! caculated from the information of route messages.
! Once the network is established, each node can
! either sends its own packets or forwards its
! children's packets to its parent node. Packets
! can be forwarded to the base station in a multihop
! fashion.With this scheme, blast win the 90\%+
! receive rate of data packet in ideal environment.
! The two drawbacks of current version of blast are:
! 1. The network setup time is relatively long,
! it is because it needs to collect enough route
! packet to caculate the reliability, 2. it needs a
! mechanism to operate in power saving mode to extend
! the longevity of the motes.
!
The \blast\ protocol has the following characteristics:

\subsection{Previous work with outdoor sensors}
! %\input{spie_reviews}
!
!
!
! \paragraph{Ganesan et al.}~\cite{ganesan:d2002}
! have done the first large scale study
! for sensor networks to explore the behavior of such a
! distributed system. Their data provides insight into
! designing protocols and algorithms for scalable distributed
! sensor networks. They differentiate how each of the layers
! in the protocol stack, link, medium access, routing and
! application is affected.
!
! Their study involves using 150 motes laid out in a parking lot.
! Link characteristics and statistics as well as aggregate
! statistics for packet loss, and packet forwarding are gathered.
! At the medium access layer they use timing information to
! identify metrics that capture both end-to-end properties of a
! basic flood propagation, and local properties such as contention
! and collision. At the node level, they maintain the number of
! hops to the base-station and the number of children each node
! has to take into account the clustering dynamics.
!
! What is observed at scale is termed as non-uniform flood
! propagation. This is shown by the existence of backward links,
! long links, assymetrice links, nodes that are missed out in the
! flood process and even clustering behavior wherein a few nodes
! have many children.
!
!
! \paragraph{Bulusu et al.}~\citeyear{bulusu:n2002,bulusu:n2001}
! have developed techniques for
! RF-based localiazation in sensor
! networks. Their work can be divided into two
! distinct problem areas, namely localization,
! and beacon placement. They profess a GPS-less
! environments with beacon nodes that are
! deployed with their absolute location/position
! stored within them and sensor nodes that localize
! themselves based on proximity to a subset of beacons.
!
! Some of the salient characteristics of their approach are:
!
! \begin{itemize}
!
! \item an idealized radio model with perfect spherical
! radio propagation and identical transmission range for all radios,
!
! \item a localization algorithm that relies on a
! connectivity metric threshold to decide
! which beacons to use in computation of a nodes
! position estimate, which is the centroid
! of the beacons selected.
!
! \item measurement based adaptive beacon placement,
! which can adjust the density of beacons
! and in turn increasing system lifetime,
! and reduced excessive channel interference and
! contention.
! \end{itemize}
!
! As per their results the spherical radio model
! correlates upto 90% with real conditions in
! an outdoor uncluttered environment.
!
!
!
! \paragraph{Simic et al.}~\cite{simic:sn2003}
! describe distributed computation
! and estimation of a scalar field in a sensor
! network. The scalar field could be anything
! from temperature to amount or intensity of
! light. They provide an algorithm and precise
! theoretical analysis of it.
!
! The basic idea of their algorithm is as follows.
! Each node communicates with its neighbors
! and computes the maximal difference quotient
! of the sensed scalar field. The estimate
! of the gradient at each node is taken to be
! the vector in the corresponding direction with
! norm equal to the maximal difference quotient.
! The method amounts to approximate differentiation
! of the function defined by the scalar field,
! given its value on a set of random points.
! They analyze the accuracy and complexity of
! the algorithm from a probabilistic point of
! view. The estimated probability that the
! error is small and converges to one, as the
! number of nodes goes to infinity, is shown.
!
!
! \paragraph{West et al.}~\citeyear{west:b2001}
! are designing parts of the sensor
! network architecture with microclimate
! monitoring as their application for focus.
! Their necessities for an architecture stem
! from preliminary testing. To understand the
! performance of low-power transceivers, they
! have taken propagation measurements using
! commercially available equipment in the local
! Ponderosa pine forests. An interesting
! observation made in this environment was that if
! the antenna was placed at a height of less
! than 1 meter, the range severely degraded.
!
! Some of the suggestions that they make to
! expand current sensor network implementations
! and architectures are:
! \begin{itemize}
! \item Distributed source coding of spatio-temporally
! correlated vector process.
! \item Multi-hop protocols with inter-layer
! interaction, as interaction between layers
! may prove benfecial in a more compact and power efficient system design.
! \item Coded macrodiversity in energy-limited
! multi-hop nets where a transmission using a
! basic radio is heard by multiple neighboring nodes.
! \end{itemize}
!
!
! \paragraph{Ramadurai and Sichitui}~\citeyear{ramadurai:v2003,sichitiu:ml2003}
! develop distributed algorithms
! for outdoor localization in sensor networks.
! The method is based on radio-frequency (RF) signal strength
! measurements, which tend to have a certain degree
! of inaccuracy. They define two classes of nodes,
! namely unknown and beacon nodes. The "beacon" nodes have known
! absolute (using GPS) positions, and the "unknown"
! nodes do not know their positions.
! The beacon nodes peridically inject packets which
! are used to form position estimates
! at the unknown nodes. Once an unknown nodes has
! a rough idea of its position, it can
! assist other unknown nodes in estimating
! their position.
!
! They employ two techniques for associating signal
! strength measurements to distance. Both techniques
! are grounded through preliminary empirical data.
! The first uses bounded values that associate an
! RSSI reading to a distance range, plus adding power level
! variability gives it increased accuracy and granularity.
! The second uses probabilistic position estimation,
! where any node receiving a beacon packet will
! estimate itself to be located on a surface that
! has a probability distribution dictated by a mean and
! standard deviation corresponding to the signal
! strength received.
!
! The measurements for both these approaches were
! collected outdoors with very little interference,
! however their data also indicates that even in
! heavily wooded areas the signal propagation is
! approximately circular, and hence the signal strength is
! linearly proportional to the distance.
!
!
! \paragraph{Mainwaring et al.}~\citeyear{mainwaring:a2002}
! have had success in deploying
! large scale sensor networks as part of
! a habitat monitoring project at the Great Duck
! Island. It is reflective of the domain of applications
! for which sensor networks are going to be used.
! It serves as a collection of requirements, costraints
! and guidelines that serve as a basis for a general
! sensor network architecture.
!
! They present a tierd architecture, where at the
! lowest level are sensor nodes, which perform general
! purpose computing and are organized into sensor
! patches. Individual sensor nodes transmit their data
! through a patch to a sensor network gateway which links
! the sensor patch through a local transit network to
! a remote basestation. The transit network consists
! of one or more hops of wireless links. The current
! system consists of 32 nodes on a small island off
! the coast of Maine streaming live data onto the web.
!
! The main tasks at hand that the network spends
! resources for are 1) data sampling and collection,
! 2) communications, 3) network retasking and 4)
! health and status monitoring. Keeping these in mind,
! energy required for each task is projected and taken
! into account to estimate how long the sensor nodes
! will survive.

!
! Tiny Active Messages ~\cite{hill:j2000} attempt to preserve the
! basic concepts of integrating communication with computation
! and matching communication primitives to hardware
! capabilities. Each message contains the name of a
! user-level handler to be invoked on a target node upon arrival
! and a data payload to pass in as arguments. The handler function
! serves the dual purpose of extracting the message from the network
! and either integrating the data into the computation
! or sending a response message. The basic paradigm of typed messages
! causing handlers to be invoked upon arrival matches up
! well with the event based programming model supported
! by TinyOS (the operating system) and demanded by the underlying
! sensor hardware. The low overhead associated with event based
! notification is complementary to the limited resources of networked
! sensors. Applications do not need to waste resources
! while waiting for messages to arrive. Additionally,
! the overlap of computational work with application
! level communication is essential. Execution contexts and
! stack space must never be wasted because applications are
! blocked, waiting for communication. Essentially, the active
! messages communication model can be viewed as a
! distributed eventing model where networked nodes send
! each other events.

Update of /cvsroot/firebug/firebug/web In directory sc8-pr-cvs1:/tmp/cvs-serv7090 Added Files: blast.html Log Message: . --- NEW FILE: blast.html --- <h2>Blast</h2> Blast is a routing stack of wireless ad-hoc networks for mote sensing application. Sensor readings are collected and encapsulated by the applications, blast will establish a self organizing network among the nodes,and route the packet to the basestation. All nodes in the network broadcast route messages, so every mode can choose parent node based on the link reliability caculated from the information of route messages. Once the network is established, each node can either sends its own packets or forwards its children's packets to its parent node. Packets can be forwarded to the base station in a multihop fashion.With this scheme, blast win the 90%+ receive rate of data packet in ideal environment. The two drawbacks of current version of blast are : The network setup time is relatively long, it is because it needs to collect enough route packet to caculate the reliability, another is it needs a mechanism to operate in power_saved mode to extend the longevity of the motes. |
