Data Dissemination in Cognitive Radio Networks
In this report, we first describe the problem that we are dealing with i.e. data dissemination in multi-hop cognitive radio networks. To address this problem, we propose a channel selection strategy named ‘SURF’. We evaluate the proposed channel selection strategy in both single-hop and multi-hop scenarios and compared it with relevant approaches. So far, one technical report and a poster is pu...
متن کاملSecurity in Cognitive Radio Networks Security in Cognitive Radio Networks
While bringing the potential for solving the spectrum underutilization problem using methods such as dynamic and opportunistic spectrum access, Cognitive Radios (CRs) also bring a set of security issues and potential breaches that have to be addressed. These issues come out mainly from the two important capabilities implemented within CRs: their cognition ability and reconfigurability. This cha...
متن کاملOn Multipath Transmission Scheduling in Cognitive Radio Mesh Networks
Nodes in a cognitive radio mesh network comprised of secondary users may select from a set of available channels provided they do not interfere with primary users. This ability can improve overall network performance but introduces the question of how best to use these channels. Given a routing multipath M , we would like to choose which channels each link in M should use and a corresponding tr...
متن کاملQoS Provisioning for Multimedia Transmission in Cognitive Radio Networks
In cognitive radio (CR) networks, the perceived reduction of application layer quality of service (QoS), such as multimedia distortion, by secondary users may impede the success of CR technologies. Most previous work in CR networks ignores application layer QoS. In this paper we take an integrated design approach to jointly optimize multimedia intra refreshing rate, an application layer paramet...
متن کاملHigh data rate transmission in high resolution radio astronomy - vlbiGRID
Recent developments in Very Long Baseline Interferometry (VLBI) radio astronomy are aimed at improving reliability and reducing the cost of operations by moving from a custom made tape based system to using exchangeable disks in PCs. The advent of the iGRID 2002 exhibition in September 2002 with the availability of high data rate international links gave us the opportunity to try transferring t...
