Learning-Based Spectrum Selection in Cognitive Radio Ad Hoc Networks
Cognitive Radio Ad Hoc Networks (CRAHNs) must identify the best operational characteristics based on the local spectrum availability, reachability with other nodes, choice of spectrum, while maintaining an acceptable end-to-end performance. The distributed nature of the operation forces each node to act autonomously, and yet has a goal of optimizing the overall network performance. These unique...
متن کاملPower-aware ad hoc cognitive packet networks
This paper proposes a new energy efficient algorithm to find and maintain routes in mobile ad hoc networks. The proposal borrows the notion of learning from a previous research on cognitive packet networks (CPN) to create a robust routing protocol. Our idea uses smart packets that exploit the use of unicasts and broadcasts to search for routes. Because unicasts impose lower overall overhead, th...
متن کاملCooperative Spectrum Sensing with Optimal Sensing Ranges in Cognitive Radio Ad-Hoc Networks
Cognitive radio has been proposed as an innovative and effective technology to exploit the efficient reuse of the precious radio spectrum. In spectrum sensing which is a crucial step in cognitive radio networks, an adequate sensing range needs to be defined to prevent the hidden transmitter/receiver problems. Moreover, a secondary user may have unreliable detection of the existent primary users...
متن کاملRSSI based Optimum Transmission Power Ad-Hoc
One of the major challenges faced by the Ad hoc networks is battery life of the nodes. By reducing or optimizing the energy consumed during the communication, the life of the respective nodes can be increased thereby improving the network lifetime. However the energy consumed in communication is greatly affected by the quality of link between the nodes. In this paper, we propose RSSI based Opti...
متن کاملSpectrum Sensing For Cognitive Radio Employing Time-Domain Signal Cross Correlation For Vehicular Ad-Hoc Networks
Recent advancement in vehicular wireless applications is also a major contributing factor in spectrum scarcity. Cognitive radio technique is applied to Vehicular Ad hoc Networks (VANETs) to increase frequency bandwidth. Fast and reliable detection of primary user is the key component of cognitive radio networks. In this paper, we are considering a CR system that uses spectrum sensing based on t...
