A Fusion Rule Based on Connectivity in Wireless Sensor Networks

摘要

Wireless sensor networks (WSNs) have become a very active research area and apply in target detection and fusion in recent years. In this paper, we focus on the connectivity characteristics of WSNs and the influence of network connectivity on target detection performance. Based on distributed detection fusion system and network connectivity, we propose a new fusion rule to improve detection. The influence of nodes number, signal to noise ratio and nodes communication radius on system performance is analyzed and simulated in detail. The experiments and simulations also compare the performance differences between the proposed fusion rule and the traditional counting rule.
