Channel-aware and queue-aware joint-layer resource optimization for cognitive radio networks

Resource-Aware Dynamic Spectrum Pricing for Cognitive Radio Networks

Sharing of spectrum has been identified as a key requirement in cognitive radio networks(CRNs). We address the problem of spectrum sharing with spectrum pricing where the primary user wants to sell the spectrum to the secondary users. By equilibrium pricing scheme, each of the players in the spectrum sharing game aims to take the strategy which maximize its own profit under sojourn-time constra...

Interference-Aware and Cluster Based Multicast Routing in Multi-Radio Multi-Channel Wireless Mesh Networks

Multicast routing is one of the most important services in Multi Radio Multi Channel (MRMC) Wireless Mesh Networks (WMN). Multicast routing performance in WMNs could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. In this paper we want to address the multicast routing problem for a given channel assignment in WMNs. The channels...

Interference-aware resource management techniques for cognitive radio networks

Attack-Aware Cooperative Spectrum Sensing in Cognitive Radio Networks under Byzantine Attack

Cooperative Spectrum Sensing (CSS) is an effective approach to overcome the impact of multi-path fading and shadowing issues. The reliability of CSS can be severely degraded under Byzantine attack, which may be caused by either malfunctioning sensing terminals or malicious nodes. Almost, the previous studies have not analyzed and considered the attack in their models. The present study introduc...

A resource intensive traffic-aware scheme using energy-aware routing in cognitive radio networks

This paper proposes a resource intensive traffic-aware scheme, incorporated into an energy-efficient routing protocol that enables energy conservation and efficient data flow coordination, among secondary communicating nodes with heterogeneous spectrum availability in distributed cognitive radio networks. The proposed scheme associates the backward difference traffic moments with the sleep-time...
