    Channel Allocation in Non-Cooperative Multi-Radio Multi-Channel Wireless Networks

    While tremendous efforts have been made on channel allocation problems in wireless networks, most of them are on cooperative networks with few exceptions. Among those works on non-cooperative networks, none of them considers the network with multiple collision domains. Instead, they all assume the single collision domain, where all transmissions...
