ABSTRACT: The increasing interest for wireless communication services and scarcity of
radio spectrum resources have created the need for a more flexible and efficient
usage of the radio frequency bands. Cognitive Radio (CR) emerges as an
important trend for a solution to this problem. Spectrum sensing is a crucial
function in a CR system. Cooperative spectrum sensing can overcome fading
and shadowing effects, and hence increase the reliability of primary user detection.
In this paper we consider a system model of a dedicated detect-andforward
wireless sensor network (DetF WSN) for cooperative spectrum sensing
with k-out-of-n decision fusion in the presence of reporting channels errors.
Using this model we consider the design of a spatial reuse media access
control (MAC) protocol based on TDMA/OFDMA to resolve conflicts and
conserve resources for intra-WSN communication. The influence of the MAC
protocol on spectrum sensing performance of the WSN is a key consideration.
Two design approaches, using greedy and adaptive simulated annealing
(ASA) algorithms, are considered in detail. Performance results assuming a
grid network in a Rician fading environment are presented for the two design
approaches.
