Title: Cooperative Routing Protocol for Cognitive Radio Ad-hoc Networks

Recently, cooperative communication has become a very attractive research topic as researchers believe that it benefits system capacity and energy efficiency if designed wisely. Many projects have been conducted to study how to employ cooperative diversity in an ad hoc network. To address the lack of a systematic cooperative routing scheme, we propose a novel routing protocol called Cognitive Radio Cooperative Communication Routing Protocol (CRCPR) for data transmission in a Mobile Ad hoc Network (MANET). Since node mobility can cause frequent radio link breaks in MANETs, one of CRCPR’s pivotal design targets is to enhance resilience to mitigate the mobility issue, therefore improving the overall network throughput. The proposed CRCPR scheme exploits a methodical routing structure based on a cooperative topology to ameliorate the influence of link breaks. Furthermore, assuming nodes in MANETs are mostly battery-operated, CRCPR takes the energy constraint into account and aims to minimize the energy consumption when packets are forwarded. In addition, cooperative diversity in CRCPR improves the energy efficiency during data transmission. As well as designing a new routing protocol for ad hoc networks, including route discovery, route selection, route maintenance and route reconstruction, the proposed scheme is implemented within an Opnet-based simulation environment and evaluated under a variety of realistic conditions. The results confirm that the protocol improves mobility resilience, saves energy via cooperative communication.
