A Routing Mechanism for Cognitive Radio Ad Hoc Networks
Qian Zhao, Guangsheng Feng, Zheng Chen · Advanced science and technology letters · 2014
Node failure and link failure happen frequently in cognitive radio Ad Hoc networks. In order to maintain the connection between cognitive users and resume their communication as soon as possible when the current route is invalid, a reliable routing mechanism is proposed. Meanwhile, how to choose candidate route, maintain or rebuild route are also elaborated. Numerical simulations show that the proposed protocol has a higher performance compared with other typical protocols.
