针对无线传感器网络中的节点能量消耗不均衡问题,将协同进化的思想应用到无线传感器网络路由协议中,提出了一种基于节点邻域空间划分的负载均衡路由协议(LRDNS).该协议将节点一跳邻域空间内的节点划分为多个空间,通过子空间的相互协作决定最优下一跳节点;并采用多路径数据分流策略,通过选择最优或次优路径进行数据的转发来提高整个网络的负载均衡性.仿真结果表明,LRDNS能够有效地降低节点能量的消耗,均衡网络的负载,延长网络的生存周期.
Aiming at the unbalanced energy consumption of nodes in wireless sensor networks, this paper applies the idea of co-evolution to the routing protocols of wireless sensor networks (WSNs), and proposes a load balancing routing protocol (LRDNS) based on node neighborhood space partitioning. The nodes in one-hop neighborhood are divided into several spaces, and the optimal next-hop nodes are determined through the cooperation of subspaces. The multi-path data offloading strategy is adopted to improve the data forwarding by selecting the optimal or suboptimal path The load balancing of the whole network.The simulation results show that LRDNS can effectively reduce the node energy consumption, balance the network load and prolong the life cycle of the network.
