摘要: 针对现有ZigBee网络多PAN路由算法在路由构建过程中通信开销、传输时延和能耗较大的问题,提出一种基于跨层机制的能耗均衡路由算法——ERBCD(Energy-balanced Routing algorithm Based on Cross-layer Design)。该算法采用梯度探测反馈方式构建网关至节点的下行多径路由;引入跨层机制更新邻居节点的剩余能量信息;设计包含跳数和节点剩余能量的合成路由度量标准以减轻节点负载,均衡网络节点能耗。理论分析证明了ERBCD算法的有效性。仿真结果表明与现有典型算法IP-AODV相比,ERBCD算法大大降低了网络通信开销和数据分组平均能耗,并延长了网络生存期延。
