Packet Error Rate analysis of IEEE 802.15.4 under 802.11g and Bluetooth interferences

This paper approaches the issues concerning the coexistence of the Wireless Sensor Networks (WSN) IEEE 802.15.4, the IEEE 802.11g wireless networks and the ad-hoc Bluetooth networks that function within the same 2.4 GHz band. The quality of communication is assessed by analyzing the PER (Packet Error Rate) parameter. The tests are based on the worst case scenario presumption, which entails the occurrence of the channel overlapping phenomenon. The paper suggests a practical approach through the assessment of the PER parameter at various separation distances between networks and by varying the retransmissions of a packet for the 802.15.4 network.
