文摘

Multi-hop cellular network (MCN) is a wireless communication architecture that combines the benefits of conventional single-hop cellular networks and multi-hop ad hoc relaying networks. The route selection in MCN depends on the availability of intermediate nodes and their neighborhood connectivity. Cognitive radio (CR) is an emerging communication paradigm that exploits the available radio frequencies opportunistically for the effective utilization of the radio frequency spectrum. The incorporation of CR and mobile ad hoc network routing protocols in MCN could potentially improve the spectrum utilization and the routing performance of MCN. This paper firstly presents the proposed model for the multi-interface CR mobile node with transceiver synchronization and then investigates its opportunistic spectrum utilization and routing performance in MCN.
