基于虚拟力的能耗均衡层次路由协议

大规模无线传感器网络路由转发中主要存在节点负载不均衡,容易导致"热区"中节点过早死亡,从而大大降低传感器网络生存时间的问题.针对这一问题,本文提出一种新的路由协议ECFP,首先利用节点与Sink节点的最短跳数建立簇首竞争半径,根据簇首竞争半径选择剩余能量较高、链路质量较好的节点出任簇首,然后基于虚拟力模型进行非均匀分簇,最后簇首之间多跳将信息传输至Sink节点.实验结果表明本文提出的协议在能耗均衡性和网络生存时间方面都具有较好的性能.

Energy-consuming Balanced Hierarchical Routing Protocol Based on Virtual Force

The main problem of the large-scale wireless sensor network route forwarding is the burden of nodes is une-ven,which easily leads to premature death of the"hot zone"nodes,thus greatly reducing the survival time of sensor network. In order to solve this problem,this paper proposes a new routing protocol called ECFP. Firstly,it use the minimum number of hops of nodes and Sink nodes to establish the competition radius of cluster head.The cluster head competition radius is used to select the nodes of higher remaining energy and link quality as the cluster head nodes, then the non-uniform clustering is carried out based on the virtual force model. Finally,the multi-hop information be-tween the cluster head nodes is transmitted to the Sink node. The simulation results shows that the protocol proposed in this paper has a good performance in terms of energy consumption balance and network lifetime.
