Coexistence Model of Zigbee & IEEE 802.11b (WLAN) in Ubiquitous Network Environment
IEEE 802.15.4 standard is used for low rate, short distance wireless communication. However, due to its low power it is greatly affected by interference provided by other wireless technology working on same ISM (Industrial, Scientific & Medical) band, such as IEEE 802.11b/g & Bluetooth. In ubiquitous network environment the authors have two different heterogeneous communication systems coexists in single place. In this paper, they use an analytic model and an experimental set up for the coexistence among Zigbee, &WLAN. The model focuses on two aspects, namely power & timing. These two jointly impacts on the performance of IEEE 802.15.4 wireless network. Zigbee is main component of wireless sensor network, so therefore to study about performance of network should be need in interference environment.
