| Abstract(in English) | Cognitive radio networks, in which each node can adaptively change radio frequencies (channels) to communicate with each other, create different topologies based on channels assigned to each node. Because routing is generally performed after topology is fixed by the channel assignment, some channels become unnecessary for creating links along active paths, which causes to reduce the capacity of links along active paths. We propose to release these unnecessary channels by detecting them based on the routing tables of a node and its neighbor nodes. We also show that the proposed scheme improves the feasibility of traffic accommodation as well as link capacity through simulation results. |
