Abstract: Wireless sensor network (WSN) is a network with miniaturized sensor nodes deployed in a region. These nodes have limited battery, a communication subsystem, mobility subsystem and sensor subsystem. Adaptive probabilistic broadcast is a data dissemination protocol for network level broadcast with adaptive parameters based on the probabilistic broadcast. This protocol reduces the broadcast storm problem in WSN. Energy efficiency is the major issue in WSN, as recharging and replacement of batteries is difficult. In this paper the performance of the Adaptive probabilistic broadcast routing is evaluated with the help of simulation tool Omnet++. Mixim framework of Omnet++ simulation tool provides a choice in application layer between Sensor application layer, Burst application layer battery and Traffic generator. Simulative results are used to show the effect of varied application header length (256 bit, 512 bit, 1024 bit) of Burst application layer battery on Backoff duration, latency, mean number of hops, number of frames dropped with interference and mean power consumption.

Keywords: Wireless sensor network, Adaptive probabilistic broadcast, Omnet++, Burst application layer, header length, backoff, mean power consumption.
