摘要:In cognitive radio Ad Hoc networks, the events of node failure and link failure maybe happen frequently, especially the primary users will access the authorized channel whenever possible. 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 CARC is proposed, which employs primary and candidate route to communicate under differential cases. Meanwhile, how to choose candidate route, maintain or rebuild route are also elaborated. Numerical simulations show that the proposed CARC protocol has a higher performance compared with other typical protocols.
