Abstract :
Due to the special characteristics of wireless sensor networks, traditional MAC approaches are not suitable for them. So designing MAC protocol for WSNs in a specific manner is critical to meet their intrinsic constraints. In this paper, we proposed an energy efficient MAC protocol which reduce energy consumption due to idle listening and control packet overhead. It is called W-MAC. W-MAC protocol reduces the sleep delay raised from the sleep schedule over multi-hops, thereby, it is more efficient in delay sensitive and large scale applications. To evaluate the proposed protocol, it is implemented it in ns-2 and compared it with Adaptive-SMAC. The results show that W-MAC proposed MAC has a considerable reduction in energy consumption up to 21% compared to Adaptive-SMAC in the best case. In addition, the mathematical calculation and simulation results show that the end-to-end delay is reduced up to almost 32% in terms of time compared to Adaptive-SMAC.
