In emerging ubiquitous wireless environments, mobile devices can have multiple communication modules such as WLAN (Wireless Local Area Network) and Zigbee. Since IEEE802.15.4 Zigbee devices and IEEE802.11b WLAN devices share the same 2.4GHz ISM band, a Zigbee network operating in a low power environment can be severely interfered by overlapped WLAN networks with much larger bandwidth due to higher...
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...
