摘要
无线ad-hoc网络部署在非人为控制的外部环境中,采用电池供电。在这种应用环境中,如何通过合理的路由协议设计降低能量开销、提高网络的生存时间是近年来研究的热点。文章提出一种结合链路质量与能效的跨层路由协议。在路由建立阶段综合考虑链路质量、发送数据包的能耗和节点剩余能量来建立路由。通过在路由维护阶段对链路质量和节点剩余能量进行检测,预测路由中断的发生,并进行本地修复。通过在IEEE 802.15.4 Matlab模拟器下进行仿真,验证了该协议能够有效地提高网络的生存时间、数据投递率及AODV协议的性能和稳定性。
Abstract
Wireless ad-hoc network is usually used in non-artificially controlled external environment, applying battery as its power supply. Therefore, how to reduce power consumption via legitimate routing protocol and improving the lifetime of the network, are being widely studied in recent years. In this paper, it is proposd a cross-layer routing protocol that considers link quality and energy-efficiency simultaneously during the routing establishment phase. Then during the routing maintenance phase, the protocol utilizes link quality and the remaining energy of nodes to predict the routing interruption and perform local repair. The protocol is simulated on IEEE 802.15.4 Matlab simulator. The results show that our protocol effectively improves lifetime and the data delivery ratio of the network, and also the performance and stability of AODV.
