A Reliable Broadcast Scheme for Sensor Networks

Abstract

In this short technical report, we present a simple yet effective reliable broadcast protocol for sensor networks. This protocol disseminates packets throughout the sensor network by flooding and recovers from losses resulting from collisions by having hosts retransmit packets whenever they notice that their neighbors have fallen behind. Such retransmissions serve to flood the appropriate packets throughout the regions of the sensor network that did not receive the given packets as a result of prior flooding attempts.
