In this paper, a novel Wireless Sensor Network (WSN) assisted by M-ary Frequency-Shift Keying (MFSK) modulation and Frequency-Hopping (FH), referred to as the FH/MFSK WSN, is proposed to monitor multiple Source Events (SEs). In the FH/MFSK WSN, the multiple SEs of each with multiple states are observed by a common group of Local SeNsors (LSNs), each of which observes simultaneously all the SEs. The LSNs convey their decisions through wireless channels to the Fusion Center (FC) with the aid of MFSK and FH. At the FC, the SEs' states are detected using non-coherent fusion rules. In this contribution, two non-coherent fusion rules are investigated.
