摘要：
本文提出了一种创新的三层无线传感器网络（WSN）系统，它监测M元事件，如温度，压力，湿度等的帮助下，地理上分布的传感器。传感器通过独立的瑞利衰落信道，使用多进制频移键控（MFSK）调制方案将信号传送到融合中心。在融合中心，检测发生的帮助下，选择合并（SC）分集方案，这保证了一个简单而经济的接收器电路。借助于各种模拟，系统的性能和功效已被分析通过改变调制水平，本地传感器的数量和正确检测的概率的传感器。研究证明，三层无线传感器网络系统是一个经济和可靠的系统，能够正确检测的M-ary事件，结合频率分集和天线分集。
英文摘要：
This paper proposes an innovative triple layer Wireless Sensor Network (WSN) system, which monitors M-ary events like temperature, pressure, humidity, etc. with the help of geographically distributed sensors. The sensors convey signals to the fusion centre using M-ary Frequency Shift Keying (MFSK)modulation scheme over independent Rayleigh fading channels. At the fusion centre, detection takes place with the help of Selection Combining (SC) diversity scheme, which assures a simple and economical receiver circuitry. With the aid of various simulations, the performance and efficacy of the system has been analyzed by varying modulation levels, number of local sensors and probability of correct detection by the sensors. The study endeavors to prove that triple layer WSN system is an economical and dependable system capable of correct detection of M-ary events by integrating frequency diversity together with antenna diversity.
