| description | Routing in cognitive networks is a challenging problem due to the primary users’ (PU) activities and mobility. Multipath routing is a general solution to improve reliability of connections. Routes closeness metric was proposed for multipath routing in cognitive networks; however, the proposed technique supports only one channel [4]. This work proposes a multichannel assignment technique for multipath routing using routes closeness as the routing metric. It relies on the nodes of the different paths to early detect the existence of PUs and notify nodes on other routes to avoid using the PU’s channel that is going to be interrupted. In case the field has PUs occupying all channels, channels assigned to nodes based on how far the nodes are from the PU. Simulation results show the effectiveness of the channel assignment technique in increasing end-to-end throughput and decreasing delay. |
