Distributed Channel Assignment in Multi-Radio 802.11 Mesh Networks

Category: Software and Web Development, Networking and Communications

Overview To increase the utilization of the available frequency channel space in 802.11-based wireless mesh networks, recent work has explored solutions based on multi-radio stations. This paper reports on the design and experimental study of a distributed, self-stabilizing mechanism that assigns channels to multi-radio nodes in wireless mesh networks. It takes a modular approach by decoupling the channel selection decision from the data forwarding mechanism, which makes the solution readily applicable to real-world operation when used with emerging multi-radio routing solutions. This paper demonstrates the efficacy of the protocol on a real-world, 14-node testbed comprised of nodes, each equipped with an 802.11a card and an 802.11g card.
