Routing is a challenging issue when dealing with the multi-hop cognitive radio networks (CRNs). The stability of a route is highly influenced by the behaviour of the primary user (PU). The more frequently PU changes its activity, the less stable spectrum availability the cognitive user has. This causes tremendous stability fluctuation of the route in CRNs.(More)
In mobile Multi-hop Cognitive radio network (CRN) routing is a challenging issue since Secondary users (SU) mobility and Primary user (PU) activity may cause radio links to break frequently. The stability and reliability of a route depends on the availability of the links constituting the route. In this paper, we propose a mobility aware stable routing(More)
In multi-hop wireless mesh network (WMN), hidden node is one of the major problems when IEEE 802.11 DCF is used as a MAC protocol. It causes data packet collisions between the multi-hop links and significantly affects the network performance. In order to avoid this problem, a novel routing scheme is proposed in this paper. It uses a high sensitive sensing(More)
