Many studies have been done using analysis and simulation
to evaluate the effect of Wi-Fi on ZigBee and vice versa.
Authors in[1] have conducted several test bed experiments
to measure the mutual effects of coexistence between
networks that operate in the2.4 Ghz ISM band, such as
ZigBee Bluetooth, Wi-Fi-b and microwave. The conducted
experiments compromise a scenario of 5 test cases that
shows that ZigBee is affected by Wi-Fi-b, WIFI, Bluetooth
and microwave. The result of this test shows that when
running ZigBee and WiFi-b together, 90% of ZigBee-frames
are corrupted and no impact of ZigBee on WiFi-b.In [2] the
authors derived an analytical model to determine the impact
of ZigBee network on the Wi-Fi-b nodes. They
experimented and shown that ZigBee network usually have
little to no impact on the Wi-Fi-b nodes performance, unless
Wi-Fi-b STA is located very close to ZigBee high activity
clusters then the result may change.
