基于交叉层设计的能量负载平衡自组网路由技术

针对已有无线自组网能量平衡路由研究缺少对无线链路信道状态考虑的问题,提出了绕过繁忙区域的能量负载平衡路由技术,采用交叉层设计方法,将M AC层提取的物理信道繁忙程度与节点剩余能量、路径跳数相结合,形成路由度量,并基于改进AODV(ad hoc on dem and d istancevector)路由协议基础上实现路由策略。通过N S-2环境中仿真实验,该技术比传统AODV协议对成功递交分组数、分组成功递交率提高10%的同时,很好地控制了分组延迟的增加,在网络负载增加时甚至更低。

Cross-layer design-based energy load balancing in wireless ad hoc networks

Current energy balancing algorithms for mobile wireless ad-hoc networks do not consider the state of the wireless channel.An energy balancing algorithm based on cross-layer design was developed which analyzes the physical channel busy ratio and the residual energy of nodes.The algorithm uses hops as route metrics and improves routing policies based on the ad hoc on demand distance vector protocol.Simulation results show that the algorithm gives about 10% improvement on total delivered packets and delivery ratio,with controlled packet delay.
