Abstract

Many energy-efficient Receiver Initiated Asynchronous Duty-Cycle MAC protocol for wireless sensor networks (WSNs) have been proposed. Most nodes suffer from significant performance Degradation for burst traffic, due to randomly waking up to communicate with each other. The proposed protocol is new receiver initiated asynchronous duty-cycle MAC protocol for burst traffic . By adaptively adjusting beacon time of the receiver and it schedules the sender listening time based on scheduled period, by this high energy efficiency and low end-to-end packet delivery latency for burst traffic is achieved. We have evaluated the performance of MAC through detailed ns- 2 simulation. The simulation results show that this protocol reduce end-to-end packet delivery latency and energy consumption under various data rates in different topologies compared with RI-MAC
