      <h2>Time, Location</h2>
!       7/16/2003 Wed. 1:40PM In Front of Library.
  
      <h2>Context</h2>
      Purpose:<br>
      The experiment measured the success rate
      for packet transmission for the Mica2 mote uploaded with 
      CollectDataFB application.
!     <P>
      BaseStation mote was set up as the starting point, we deplyed 
      the mote with CollectData application at 5,10,20,40,80,160,300
      feet from the starting point for each test, and ListenFB logged 
      all the packets the basestation received into the database.
!     <P>
!     Due to time took for the network establishment between the mote 
      and basestaton, we disregarded the packets lost during this 
      period, and caculate the success rate with the following:<br>
!     success rate =(Number of Ending Packet Cnt-Number of Beginning cnt)/Number of Total Packet

      <h2>Time, Location</h2>
! 
!       <p>
!       7/16/2003 Wed. 1:40PM In front of Doe library.
!       The yard in front of Doe library is bowl shaped
!       with a gentle slope to the west.  The base station 
!       was located at the eastern, higher end of the yard,
!       the motes deployed approximately downhill to the
!       west along a line.  The ground surface is mown grass,
!       (i.e., turf), parts of which are sodden with moisture collected 
!       on the underground roof of the library.  At least one 
!       drainage culvert crosses under or runs semi-parallel
!       to the line along which the motes were deployed.
!        The weather was warm (72 F), clear and sunny.
!       </p>

  <h2>Problems</h2>
! 
! Some issues with the data collection became apparent once 
! the database logging application was started:
! 
! <ol>
!   <li>Time stamping packets:  This has been solved by using the
! 	TIMESTAMP facility in MySQL.  Packet data is timestamped
! 	when inserted into the database.  The lag time doing this
! 	rather than extracting a time stamp from a packet is
! 	negligible compared to the 3000 ms packet transmission
! 	rate.
!    </li>
!   
!    <li>Database name on command line: The database logging
!       application was initially coded to send data to the 
!       firebug database.  This most inconvenient, and has now 
!       been changed so that the database name must be specified
!       on the command line.  We assume that the database already 
!       exists in the MySQL server.
!    </li>
!   
!    <li>Blast/mh6 retrsnsmission.
!    </li>
