Using Cognitive Radio for Improving the Capacity of Wireless Mesh Networks
Ricardo Carvalho Pereira, Richard Demo Souza, Marcelo Eduardo Pellenz · 2008
We propose the application of the overlay cognitive radio model to the communication of links within a wireless mesh networks. Based on the communication paradigm proposed by Jovicic and Viswanath, it is possible to have two concurrent transmissions in a given interference region. As as result, considerable network capacity gains are achieved. For the simple case of a network with a chain topology, the gains are as high as 33%.
