NPA Networks and Performance Analysis

Throughput dynamic policy: Our theoretical results suggest that the dynamic policies, for both metrics (delay and through- put), provide better results for OFF periods that underlie

Therefore, in this work we address the TV spectrum management problem taking into account guard bands and considering a non-cooperative game theoretical approach, where unlicensed

On the one hand, while a centralized approach to the channel assignment problem in CRNs usually obtains best results considering solely the utilization of network capacity,

Transport layer protocols provide end-to-end data delivery without having any knowledge on the network structure, like number of hops, parameters of communication link and so

Considering unknown and different channels between the primary and the cognitive users, an averaged received power spectrum across all the cognitive users is estimated by each

Abstract—In this paper, a centralized Power Control (PC) scheme aided by interference channel gain learning is proposed to allow a Cognitive Radio (CR) network to access the

The proposed solution, LLE-TCP, avoids TCP ACK transmission over the wireless link through local generation of ACKs at the sender node (in a single-hop scenario) or at the base

The proposed coalition formation algorithm is based on two simple rules of merge- and-split that enable SUs in a cognitive network to cooperate for improving their detection
