A home network is a residential local area network, in which users are networking their PCs, laptops or wireless multimedia appliances to use a single residential access point (AP) or gateway connecting to the Internet. As networkcapable appliances continue to gain momentum in the home, home networks are becoming increasingly popular. The problem arising from the increasing number of "wireless home" is the interference introduced from neighbor's home networks which leads to throughput dropped

We are considering how home wireless network can selfconfigure its operating channel to minimize interference with other networks instead of how network administrator assigns channel to different APs. In this paper, we propose a peerassisted channel assignment algorithm, termed PACA, for home wireless LAN based on local information. A newly power on AP automatically configures itself to operate on a channel with least interference. Mobile node helps other APs to do channel assignment and switching dynamically by providing traffic load information. Our simulation and experimental measurements show that the algorithm reduces interference among different networks and improves user throughput. © 1-4244-0357-X/06/$20.00 2006 IEEE This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE GLOBECOM 2006 proceedings. © 1-4244-0357-X/06/$20.00 2006 IEEE This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE GLOBECOM 2006 proceedings. CU = Type II Load × α + Type I Load where α > 1. CU is a weighted sum of the two loads in different types. The lower the value of CU, the better the channel is in terms of interference.
