The tremendous increase in wireless communication networks in the last few decades has lead to spectrum scarcity, which has already set the needs for efficient spectrum utilization. The juvenile and up-coming field of Cognitive radio (CR) networks is the promises to alleviate the spectrum scarcity problem, by allow devices to share the spectrum with secondary users. This improves the inefficient spectrum utilization in the bands reserved for the licensed users. This paper work investigates the use of proposed TCP-friendly protocol for variation in spectrum availability with time and periodic spectrum sensing done by the CR users. The proposed protocol employs the secondary nodes in not-fully blocked mode, to achieve significant improvements in classical TCP in a CR ad hoc network environment. In this paper we present a multipath routing protocol, that uses on demand distance vector routing, called Ad hoc On-demand Multipath Distance Vector (AOMDV) Routing Protocol. We analyze its performance using Network simulator (NS-2) software tool for the simulation purpose to give effective result of cognitive radio ad hoc networks.
