Stay or switch? Analysis and comparison of delays in cognitive radio networks with interweave and underlay spectrum access

The problem has been modeled as a non-cooperative game where secondary users access simultaneously multiple spectrum bands left available by primary users, optimizing their

The problem has been modeled as a non-cooperative game where secondary users access simultaneously multiple spec- trum bands left available by primary users, optimizing their

This paper overcomes these limitations by proposing a novel game theoretic model that solves the joint problem of spectrum allocation and price setting, considering both

Similarly, [4] describes the methods implemented in the package parcor that provides several regularization frameworks (PLS, ridge, LASSO...) to infer networks by means of

Of these mentioned paradigms, this pa- per focuses on the performance analysis of the USs in terms of the estimation-throughput tradeoff considering transmit power control at

● Based on the proposed model, we capture the effect of imperfect channel knowledge by employing an outage constraint on the received power at the PR that restrains the

3) Estimation-Throughput Tradeoff: Besides, we propose a successful incorporation of the time allocated for the chan- nel estimation in the secondary system’s frame structure. The

In this survey, we have presented various techniques of dynamic spectrum access in cognitive radio networks, starting by auctions where the utility function of the
