摘要

Wireless sensor networks take great importance in recent years according to their potential applications in different areas like health monitoring, military applications, tactile system and industrial applications. In this paper the decentralized sensing with noise and band limited channel between the sensor nodes and merging stations (fusion center) for different levels of power is analyzed. The evolution of the system performance is based on the considering the wireless sensor network with direct sequence-code division multiple access (DS-CDMA) for varying levels of power. The achieved results indicate the performance is improved with employing the direct sequence-code division multiple accesses (DS-CDMA). In the situation of large sensor systems and random spreading, the decentralized detection execution is derived supposition independent and identically distributed sensor observation via random matrix theory.
