摘要： 提出了一种基于无尺度特征的传感器网络路由算法，该算法可以实现自组创建并动态调整网络的无尺度网络拓扑结构，并在该拓扑结构的上层构成虚拟骨干网，支撑整个网络的数据传输。为提高数据的冗余可靠性，采用了多路径路由的设计原则。同时结合了信息融合的概念，各骨干节点把收到的冗余互补数据遵循“先融合后转发”的原则，可有效地获得被感知对象的确知信息，大大降低了网络的传播代价，提高了网络的生命周期。

Abstract: A kind of sensor router algorithm based on free scale networks’ character is brought forward. The algorithm could realize self-organized creating and dynamic adjusting topology, and form virtual backbone network on the topology to support entire network data routing. High redundancy routing design principle is adopted so as to improve the reliability. And data fusion function is also included, in which each backbone network node fuse redundancy data gathered before spread. All these functions can obtain sensed object’s information more effective and reduce spread cost and accordingly improve life cycle of the network.
