摘要
在分析无线传感器网络(WSN)特点的基础上,把WSN路由协议分为数据为中心路由、层次路由、地理位置路由和基于QoS的路由4类路由协议进行机制研究,指出WSN路由协议未来的研究热点有:数据为中心路由协议中,如何提供高效的标准命名机制以适应复杂查询;层次路由协议中,如何选举簇头、分簇、数据融合从而使能量更高效;地理位置路由协议中,如何智能地利用地理位置信息来辅助能量有效路由等.
After describing the characteristics of wireless sensor networks, four main categories of routing protocols are explored in this paper, which are data-centric routing, hierarchical based routing, locationbased routing and QoS based routing. After that, the hotspots and tendencies for wireless sensrr networks are pointed out as follows: how to provide efficient standard naming schemes suitable for complex queries in data-centric routing; how to choose the cluster heads, form the clusters and process data aggregation so as to make the energy consumption efficient in hierarchical routing; how to utilize the location information intelligently in order to aid energy efficient routing intelligently and so on.
