Fountain Broadcast for Wireless Sensor Networks
Code dissemination in wireless ad hoc network is an important
aspect of network deployment. Once deployed, the network
nodes may still need software updates to keep up with the
changing application demand, thus making wireless broadcast
an important aspect of any wireless network deployment. We
present FBcast, a new broadcast protocol based on the principles
of modern erasure codes. FBcast provides high reliability
and data confidentiality: often considered critical for disseminating
codes. Simulation results on TOSSIM show that FBcast
offers higher reliability with lower number of retransmissions
than traditional broadcasts.
