Abstract: Wireless Sensor Networks (WSNs) consist of many tiny wireless communication and sensing devices. Multicast is the fundamental routing service used to deliver messages efficiently from a source to a set of destinations. Moreover, multicast protocols try to minimize the consumption of network resources by using the fact that several paths from the source to the destinations can be shared by multiple destinations, and the larger the path shared, the lower overall bandwidth consumption is obtained. In this paper, based on the analysis of the feature of WSNs, the existing multicast routing protocols in WSNs are classified and analyzed. The future development trend of multicast protocols in WSNs is discussed finally.

Key words: Wireless Sensor Networks(WSNs), multicast routing protocols, consumption of network resources

摘要: 无线传感器网络由小型无线通信传感设备密集部署形成。组播是一种将数据包从源节点有效传递到一组目的节点的基本路由服务技术。组播协议中,源节点到目的节点的一些路径可由多个目的节点共享,所共享的路径越大,总带宽消耗越低。在分析无线传感器网络基本特征的基础上,对无线传感器网络中现有的组播路由协议进行了分类分析和比较,最后对无线传感器网络组播路由协议的未来发展趋势提出展望。
