ABSTRACT
The dynamic spectrum access (DSA) algorithms aim to maximize network throughput by ensuring orthogonal channel allocation among secondary users (SUs) in cognitive radio network. Most of the existing DSA algorithms need prior knowledge of the number of active SUs and thus may not be suitable for battery operated resource constrained SU terminals in the infrastructure-less cognitive radio terminals. Another drawback of these algorithms is that they assume the static network with a fixed number of SUs in the network throughout the horizon and their extension for dynamic network in which SUs may enter or exit the network anytime is challenging. Thus, our goal is to design the DSA algorithms for the dynamic networks of unknown size.

Distributed channel selection in CRAHNs: A non-selfish scheme for mitigating spectrum fragmentation
In this paper, we consider the problem of spectrum sharing in CRAHNs and propose a distributed channel selection scheme. The key functionality of our proposal, best-fit channel selection (BFC) is that it accounts both the primary channel traffic ...
