基于虚拟栅格的无线传感器网络路由协议

VIRTUAL GRID BASED ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORK

提出一种基于虚拟栅格的分簇路由协议。在本协议中汇聚节点动态、随机地建立虚拟栅格,同时形成簇结构;并依据剩余能量以及簇的整体能量消耗选择簇头。本协议不但减少了控制信息和冗余信息,而且均衡了传感器节点的能量消耗。仿真的结果表明本协议是能量有效、可扩展的无线传感器路由协议。

In this paper, a cluster routing protocol based on virtual grid is proposed. The sink dynamically and randomly builds virtual grid, meanwhile forms cluster structure in the proposed protocol. It selects cluster heads according to the residual energy and the energy consumption of all nodes in each cluster. The proposed protocol reduces control message and redundancy message, and makes the energy load distributed more evenly. The results of simulations show that the proposed protocol is an energy-efficient and scalable routing protocol for wireless sensor networks.
