摘要:

基于动态源路由(DSR)协议,综合考虑了来自物理层、媒质接入控制(MAC) 层、应用层的状态信息,采用跨层设计方法提出一种新的无线Mesh网络(WMN)业务流量感知和能效路由(TEER)协议。为了平衡节能和带宽等服务质量 (QoS)需求,根据统计获得的链路可用带宽和节点可用剩余能量以及负载队列占空比等状态信息,设计了表征网络节点能耗和传输情况的综合路由准则(MTEER)。仿真实验结果表明该路由协议可获得比DSR和基于功率控制的能量感知多径路由协议(EMRP)更好的网络性能,如网络寿命和吞吐量。

Abstract:

A novel Traffic-aware and energy efficient routing (TEER) protocol based on dynamic source routing(DSR) is proposed in wireless mesh network (WMN). TEER exploits information originated from media access control (MAC) and physical layer as well as that from application layer. To balancing energy efficiency and bandwidth quality of service (QoS) requirement, an integrated metric MTEER is proposed to denote the energy and transmission state of the node. TEER combines the available link bandwidth, duty cycle of load queue and the residual energy of node acquired by statistic methods. Simulation results demonstrate that TEER outperforms the performance than that of energy-aware multi-path routing protocol (EMRP)and dynamic source routing (DSR) in terms of network lifetime and throughput.

Key words: wireless mesh network, wireless mesh network, cross-layer design, traffic-aware, quality of service, routing protocol
