| Abstract: | The problem of idle listening is one of the most concerned issues in wireless sensor networks,and the duty cycling mechanism is widely used to reduce energy consumption.We present a new asynchronous MAC protocol,called Passive-Asynchronous MAC(PA-MAC).PA-MAC uses receiver-initiated data transmission scheme,asynchronous duty cycling mechanism and awakening time estimation scheme to achieve low duty cycle and high energy efficiency.Simulations have been done to evaluate the performance of the proposed new protocol,by which we can find out that,on the premise of keeping the network performance,PA-MAC can further reduce the nodes’ duty cycle,thereby reduce the energy consumption. |
