Wireless sensor networks and routing algorithm

规则的无线传感器网络结构具有提高网络容量和增强网络可配置能力的特点,路由寻址上也具有独特的优势。对于如何组建规则拓扑的无线传感器网络提出一种虚拟层次化的组网方式,详细描述了规则拓扑的组网过程。同时为了利用规则拓扑在路由上的优势,提出了一种新的基于凹凸区域策略的维序路由协议。路由算法能够解决路由空洞,同时可以使得路由跳数最少,减少了能量消耗。模拟仿真表明:协议建立路由过程快速,开销小,数据传输路径短,适合于大规模的无线传感器网络。

The regular structure of wireless sensor networks has the characteristics of improving network capacity and configurable capacity.It also has particular advantage of routing addressing.A virtual hierarchy networking mode is proposed to form the regular topology in wireless sensor networks,and the corresponding process is presented.A dimension-ordered routing protocol based on bump region is designed to utilize the advantage of regular topology in routing.This routing algorithm can not only solve the routing hole problem,but also achieve minimum hop of routing and reduce energy consumption in networks.Simulation results show that the process of routing establishing is fast,with lower overhead and shorter data transmission path.The algorithm is especially fit for large scale wireless sensor networks.
