Broadcasting is a fundamental operation in any wireless networks, more so in wireless ad hoc sensor net-works, where each sensor node has limited transmission range and battery power. Although broad-casting in wireless ad hoc sensor networks has many advantages but it can cause serious problems like - broadcast storm, which could cause a lot of contention, redundant, retransmission, collision and most importantly, drain immense amount of energy from limited battery powered sensor nodes. In this paper, the authors' objective is to reduce the number of retransmission and energy consumption of sensor nodes by using the duty cycle property of wireless ad hoc sensor networks. They propose a preamble-based broadcasting technique for wireless ad hoc sensor networks.
