基于通信节点的WSN自主聚类非均匀分簇路由协议

WSN Autonomous Cluster Heterogeneous Clustering Routing Protocol Based on Communication Nodes

针对无线传感器网络中如何有效地利用有限的节点能量来延长网络的生命周期这一问题,提出一种基于通信节点和多跳传输相结合的多因素自主聚类分簇路由协议.该协议通过结合节点的剩余能量、簇头与基站之间的距离以及邻居节点的数目等因素来优化路径节点的选择,改进了多跳传输的局部最优路径构造算法.仿真结果表明:与现有协议相比,该协议能够有效地节省传感器节点的能量,平衡网络能量分布,延长网络的使用寿命.

To solve the problem of how to effectively use the limited energy of nodes to extend the life cycle of wireless sensor networks,a multi factor autonomous clustering and clustering routing protocol based on the combination of communication nodes and multi hop transmission is proposed. This protocol optimizes the selection of path nodes by combining the remaining energy of nodes, the distance between the residual energy cluster head and the base station,and the number of neighbor nodes,and improves the local optimal path construction algorithm for multi-hop transmission. The simulation results show that compared with the existing protocols, the proposed protocol can effectively save the energy of sensor nodes,balance the energy distribution of the network,and extend the service life of the network.
