一种事件驱动型无线传感器网络的数据编码及融合算法

Data Code and Fusion Algorithm in Event Driven Wireless Sensor Networks

基于事件驱动的区域监测是无线传感器网络的一类典型应用,该网络中包括两种类型的数据,分别为对网络状态进行监控的周期性监测数据和事件发生时应传送的事件消息。基于簇结构,利用簇头和簇成员两种角色的节点,分别针对上述两种类型的数据提出不同的编码方式和对应的融合机制,同时详细分析了该编码方法和融合机制的优缺点。

Based on event driven district monitor is a type of typical model application in wireless sensor networks. There are two type data in the network, one is periodic monitor data which carries on supervision to the state of network, another is event message which deliver when event take place. Based on cluster topology structure, make use of cluster head and cluster member nodes, put forward a different data coding method and fusion mechanism to different type data respectively, and analyze the merit and shortcoming of algorithm in detail in the meantime.
