Abstract :
Energy awareness is the single most prominent factor of design in all the layers of the protocol stack for wireless sensor networks. A dynamic back-off procedure in which the size of the contention window is influenced by the real time traffic information of the network can be a good remedy to decrease the idle listening time in low loads and the probability of collisions in high loads. In this paper a new approach to dynamically adjusting the contention window size in Sensor Medium Access Control (S-MAC) protocol is investigated. We explore the effect of different duty cycles for different loads on the various performance parameters such as end-to-end latency, delivery ratio, and energy consumption to prove the efficiency of our approach.
