Overlay Cognitive Radio with Multiple Secondaries and its Application to Wireless Mesh Networks
Ricardo Carvalho Pereira, Richard Demo Souza, Marcelo Eduardo Pellenz · 2009
In this paper we extend the overlay cognitive radio model by introducing multiple secondaries. The new model allows for multiple concurrent transmissions in a wireless network. We apply the proposed scheme for the communication between nodes in a wireless mesh network. Numerical results show that considerable capacity gains are achieved when using the proposed overlay cognitive radio model with multiple secondaries.
