基于特征选择的无线传感器网络路由标识算法

针对无线传感器网络具有节点数量大、分布范围广、以数据为中心进行路由等特点,提出了一种基于特征选择的路由标识算法。该算法首先通过汇节点向传感器节点发送“询问”数据包,收到数据包的各个节点检查自身特征是否与“询问”内容相符,然后发送一个“答复”信息到网络,完成路由的标识。仿真结果证明该算法可以解决传统路由协议中的冗余信息和广播风暴,在生成、接收信息上具有更好的稳定性,并能够有限地减少能耗。

Algorithm of Routing Identify Based on Characteristic for Sensor Network

Concerning sensor networks' characteristic of the large number of sensor nodes deployed in an area and data-centric routing.This paper provides a kind of routing identify algorithm on the basis of nodes characteristic.Firstly,this algorithm sending queries packet to the networking function is implemented in the sink node and sensor nodes.Once a sensor node receives the broadcasted query packets,it then checks its current characteristic to see whether it fits the query or not.If true,the sensor node can send a response for the desired data to its networking function.Finish routing identify.The simulation results can deal with the serious redundancy and broadcast storm problems.This algorithm is more stable in terms of the number of packets generated and received.It also can save a large amount of energy.
