Abstract :
Recently, many wireless devices operate in the 2.4 GHz ISM band. Wireless personal area network (WPAN) can suffer significant performance degradation due to the interference of WLAN and Bluetooth. This paper proposes an interference-aware topology control algorithm for WPANs. In the proposed algorithm, each node adjusts the transmission power dynamically by considering the interference effect. In the meanwhile, each node maintains its local topology adaptively to minimize the interference effect. The experiment results show that the proposed algorithm outperforms the previous algorithms in terms of the energy and the delivery performances in WLAN and Bluetooth interference environments.
