【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。
[Abstract]:In order to solve the problem of communication overhead, transmission delay and energy consumption of existing multi-#en1# routing algorithms in ZigBee networks, the problem of communication overhead, transmission delay and energy consumption in routing construction is analyzed. An energy balance routing algorithm based on cross-layer mechanism, ERBCD-balanced Routing algorithm Based on Cross-layer design, is proposed. The algorithm uses gradient detection feedback to construct downlink multipath routing from gateway to node, and introduces cross-layer mechanism to update the residual energy information of neighbor nodes. A composite routing metric that includes hops and node residual energy is designed to lighten the node load. The theoretical analysis proves the effectiveness of the ERBCD algorithm, and the simulation results show that the proposed algorithm greatly reduces the network communication overhead and data packet average energy consumption, and prolongs the network lifetime compared with the existing IP-AODV algorithm.
