Research of a Wireless Sensor Network District Service Discovery Mechanism

基于服务发现机制在无线传感器网络中的重要性及必要性,提出了一种区域式的服务发现机制模型。分析了对区域式无线传感器网络服务发现机制起支撑作用的分簇路由算法和数据融合算法,改进GAF算法形成了E-GAF算法,采用了感知器数据融合算法。通过仿真,从能量消耗等多方面论证E-GAF算法和感知器数据融合算法符合区域式服务发现机制的要求。

Considering the importance and necessity of service discovery mechanism in the wireless sensor network,a district-based service discovery mechanism model is proposed.This paper analyzes the cluster-based routing algorithm and the data fusion algorithm,which are the foundations of the district-based service discovery mechanism of the wireless sensor network,and improves the GAF algorithm to form the E-GAF algorithm.Perceptron data fusion algorithm is also adopted.The simulation,which is carried out for many aspects including energy consumption,shows that the E-GAF algorithm and the perceptron data fusion algorithm both confirm to the requirements of the district-based service discovery mechanism.
