A decentralized MAC protocol for opportunistic spectrum access in cognitive wireless networks

Cognitive MAC protocols are designed to efficiently utilize the spectral resources without affecting the performance characteristics of the primary users. The use of spectrum opportunities, so called white spaces, can often require stochastic approaches due to difficulty in predicting their appearance. Infrastructure based coordinated access techniques are not a viable option for all the applications and spectrum bands. In this paper, we describe a decentralized cognitive MAC protocol based on multi-channel preamble reservation scheme. The protocol dynamically selects an available communication channel using a distributed channel selection scheme and allows nodes to be completely asynchronous to each other. Our MAC does not need a common control channel and cooperative infrastructure. We also address other practical issues such as mobility and traffic awareness in our MAC design. We have carried out performance evaluation of our protocol on an SDR testbed consisting of Wireless Open Access Research Platform (WARP). Experimental results show that our protocol is able to achieve reliable data communication even in harshly interfering environments.
