Probability Analysis of Channel Collision Between IEEE 802.15.4 and IEEE 802.11b Using Qualnet Simulation for Various Topologies
Coexistent heterogeneous wireless networks may interfere with each other and result in significant performance degradation when devices are collocated in the same environment. With the increasingly deployed Wireless Personal Area Network (WPAN) and Wireless Local Area Network (WLAN) devices, channel conflict has become very frequent and severe when one WPAN technology coexists with other WLAN technologies in the same interfering range. This paper studies the coexistence issue between IEEE 802.15.4 and IEEE 802.11b. It present analytical models on the non-conflicting channel allocation probabilities, focusing on the coexistence scenarios of IEEE 802.15.4 coexisting with IEEE 802.11b.
