一种传感器网络融合算法的优化

An optimization fusion algorithm in sensor network

针对无线传感器网络的二进制分布检测的问题,在假设无线传感器和融合中心所组成的网络是各向同性,并且总的信道容量受到制约的情况下,全面系统地研究了融合中心的优化问题,提出了在瑞利慢衰落信道条件下基于错误概率最小化的最优融合算法。

We investigate optimal fusion schemes for decentralized detection problems in which a network of wireless sensors provides relevant information about the state of nature to a fusion center. Since the wireless sensors and the fusion center form a typical multi-access channel（MAC）,there is a sum-rate capacity constraint associated with the MAC. Furthermore it can be shown that when the number of wireless sensors is big enough, the sun-rate capacity converges to a constant. In this paper, the optimal fusion scheme is given.
