摘　　要：由于无线传感器网络节点自身携带电池的特殊性,其能量有效策略的研究越来越受到人们的关注.分析了无线传感器网络数据链路层能量消耗,在S-MAC和PD算法基础上,提出了新的AP算法.仿真结果表明,AP算法合理地减少了碰撞,提高了数据包接收准确度,改进了无线传感器网络的能量有效性,并有效延长了网络的生命周期.Because of the limited power supply of nodes,wireless sensor network energy efficiency research is gaining more and more attention.The energy consumption of the MAC layer is analyzed.Based on the S-MAC protocol and PD-MAC protocol a novel algorithm AP is proposed.In simulations,the proposed protocol is evaluated in comparison with S-MAC and PD-MAC in the aspects of energy efficiency and accuracy of packets sink received.The result shows that collision probability can be reduced reasonably;that energy consumption can be reduced in a better way and that the network longevity can be enhanced efficiently.
