基于簇的路由协议是无线传感器网络的研究热点,本文针对现有的簇间路由协议没有考虑网络负载的均衡,提出一种高效节能的无线传感器网络簇间多路径路由协议。该协议基于簇头节点到汇聚节点的最小跳数生成从簇头节点到汇聚节点的多条路径,根据簇节点的剩余能量和负载将数据通信均匀分布在不同的路径上,从而达到簇头节点间的负载均衡。仿真实验结果表明,该路由协议能有效地均衡网络负载,节省簇头节点能量,从而延长网络的生存时间。
Clustering-based routing protocol is the hotspot of wireless sensor networks. In this paper, aiming at the problem that the existing inter-cluster routing protocols do not consider the balance of network load, this paper proposes an efficient and energy-saving routing protocol for inter-cluster multi-path wireless sensor networks. According to the minimum number of hops from cluster head node to sink node, this protocol generates multiple paths from cluster head node to sink node. Based on the residual energy and load of cluster node, data communication is uniformly distributed on different paths so that cluster head node Between the load balancing. The simulation results show that the routing protocol can effectively balance the network load, save the energy of cluster head node and prolong the network lifetime.
