无线传感器网络中一种基于行进启发的地理位置路由

March Inspired Geographic Routing Protocol in Wireless Sensor Networks

为了节省传感器节点有限的能量,针对无线传感器网络“多对一”通信的特点,提出了一种新的、基于地理位置信息的路由协议——基于行进启发的地理位置路由,该协议不需要等到数据包遇到“空洞”时才采取措施,而是在数据包离空洞还有一定距离时就提前绕开它,从而少走了弯路,减少了能量消耗.模拟研究表明,采用该协议建立路由的过程快速、开销小,数据传送的路径长度短,可适用于大规模的无线传感器网络,

In order to save the limited energy of the sensors, a novel geographic routing protocol called March Inspired Geographic （MIG） routing protocol is proposed for ＂many to one＂ communications in wireless sensor networks. With the proposed protocol, the packet can avoid meeting the ＂hole＂ in advance instead of bypassing the hole after it meets the hole. So this protocol decreases both the routing distance and energy consumption. Simulation studies show that this protocol can construct the route very fast with less energy consumption and achieves short routing distance, so it can be used for large-scale wireless sensor networks.
