Abstract
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 transmission power. To overcome this inter-system interference problem and guarantee the Zigbee communications, we proposed power aware adaptive technique for multiple WLAN and Zigbee environment. Measurement study is conducted through Qualnet simulation for different simulation parameters. The proposed method provides better results when compared with the conventional TDMA (Time Division Multiple Access) scheme.
