Abstract

This paper presents a novel channel assignment approach to support local broadcast in multi-radio multi-channel (MR-MC) wireless networks. The proposed algorithm intelligently assigns channels to each node based on superimposed codes. By applying superimposed codes, each node can easily locate a common channel shared with its s-closest neighbors. Under certain conditions, it is proved that our solution is able to solve the exposed terminal problem as well as the hidden terminal problem. Furthermore, with our channel assignment for local broadcast, most traditional MAC/routing protocols, though designed for single-radio single-channel (SR-SC) wireless networks, can possibly adapt to MR-MC wireless networks.
