无线自组织网络（WANET）是在没有预定拓扑的情况下彼此通信的无线终端的集合。由于WANET设备是功率有限的，网络协议应该被设计成延长这些设备的电池寿命。在本文中，我们提出了一个跨层集成的方法，功率有效的路由协议。在链路层的功率控制和网络层的路由协议之间的建议跨层集成的目的是最大限度地提高网络的生命周期。我们实现我们提出的协议作为AODV路由协议的扩展。我们评估了所提出的协议，通过全面模拟一组随机的WANET环境。我们模拟了六个不同的指标比较我们提出的协议与AODV协议。结果表明，该协议在满足吞吐量要求的同时，最大化了网络生存时间，降低了端到端时延，节省了总能耗。
A wireless ad hoc network (WANET) is a collection of wireless terminals that communicate with each other without predetermined topology. Since WANET devices are power-limited, network protocols should be designed to prolong the battery lifetime of these devices. In this paper, we propose a cross-layer integration approach for power efficient routing protocol. The proposed cross-layer integration between power control in link layer and routing protocol in network layer aims to maximize the network lifetime. We implement our proposed protocol as an extension to AODV routing protocol. We evaluated the proposed protocol by comprehensively simulating a set of random WANET environments. We simulated six different metrics comparing our proposed protocol with AODV protocol. The results showed that the proposed protocol maximizes the network lifetime, reduces the end-to-end delay, and saves the total energy consumption while achieving the throughput requirement.
