<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.
