摘　　要：为了延长无线传感器网络(WSNs)的生存时间,提出了一种基于EIETX的自适应功率控制的机会路由协议APExOR。考虑节点剩余能量,改进了IETX,给出基于EIETX的转发候选集选择策略;分析节点间链路状况,建立起相关的转发能效模型,提出了一种自适应优化转发候选集和发射功率的算法;利用以上策略和算法改进ExOR协议,提出了适合WSNs的APExOR协议。仿真实验表明:与固定功率下的ExOR协议相比,APExOR协议提高了网络吞吐量,降低了网络的能量消耗。A self-adaptive power control opportunistic routing APExOR based on EIETX is proposed to prolong lifetime of wireless sensor networks （ WSNs ）. Considering of nodes＇ residual energy, improves IETX, and the selecting strategy for forwarding candidates set based on EIETX is proposed. Forwarding energy efficiency model is established through analyzing link quality between nodes, an algorithm with self-adaptive between forwarding candidate set and transmission power is put forward. APExOR protocol based on the above strategy and algorithm is designed. Simulation results show that, compared with power fixed ExOR protocol, APExOR protocol improves throughput and decreases energy consumption of network.
