Cognitive radio is the promising radio technology, which aims to detect and utilize the temporally unused spectrum bands by sensing its radio environment in order to enhance spectrum utilization. However, these objectives bring significant challenges and required functionalities such as spectrum sensing, sharing, management and mobility for the realization of Cognitive Radio Networks (CRN). In particular, efficient spectrum sharing problem in cognitive radio communication is one of the most important problem which must be addressed in order to enhance the overall spectrum utilization in dynamic spectrum access environments. In this paper, we introduce a new BIOlogically-inspired Spectrum Sharing (BIOSS) algorithm which is based on the adaptive task allocation model in insect colonies. Without need for any coordination among the unlicensed users, MOSS enables each unlicensed user to distributively determine the appropriate channel(s) over which it can communicate. Performance evaluations clearly reveal that BIOSS achieves efficient dynamic spectrum sharing with high spectrum utilization and without any coordination among the users and hence yielding no spectrum handoff latency overhead due to coordination.

Cognitive Radio Sensor Networks Akan, Ozgur B.; Karli, Osman B.; Ergul, Ozgur (2009-07-01) Dynamic spectrum access stands as a promising and spectrum-efficient communication ion approach for resource-constrained multihop wireless sensor networks due to their event-driven communication nature, which generally yields bursty traffic depending on the event characteristics. In addition, opportunistic spectrum access may also help realize the deployment of multiple overlaid sensor networks, and eliminate collision and excessive contention delay incurred by dense node deployment. Incorporating cognitive...
Near optimal scheduling for opportunistic spectrum access over block fading channels in cognitive radio assisted vehicular network Gül, Ömer Melih; Kantarci, Burak (2022-10-01) © 2022 Elsevier Inc.With the increasing use of cognitive radio technology in vehicular communications, vehicles will be enabled with cognitive radio in the future. Cognitive radio assisted vehicular networks make cognitive radio enabled vehicles utilize licensed spectrum on highways opportunistically. This work tackles cognitive radio assisted vehicular networks including M primary users (transmitter), M primary receivers, a secondary user (transmitter) with K channels and K secondary receivers. A channel i...
Simulation and verification of security attacks on light-weight RFID protocols Ahmed, Saman; Diker Yücel, Melek; Department of Cryptography (2014) Radio Frequency Identification (RFID) technology is fast reaching all avenues of application. From retail to warehousing, tracking farm animals to monitoring medicine dosage in human body, traffic control to airport baggage control, it is penetrating all forums and industries and providing ease of deployment and automated visibility and management of inventories which was not possible with traditional barcodes. Along with its superiority over barcodes, RFID systems are also required to be costeffective to b...
Immune system based distributed node and rate selection in wireless sensor networks Atakan, Baris; Akan, Ozguer B. (2006-12-13) Wireless sensor networks (WSNs) are event-based systems that rely on the collective effort of dense deployed sensor nodes. Due to the dense deployment, since sensor observations are spatially correlated with respect to spatial location of sensor nodes, it may not be necessary for every sensor node to transmit its data. Therefore, due to the resource constraints of sensor nodes it is needed to select the minimum number of sensor nodes to transmit the data to the sink. Furthermore, to achieve the application-...
Event-driven MAC Protocol For Dual-Radio Cooperation Khatibi, Arash; Durmus, Yunus; Onur, Ertan; Niemegeers, Ignas (2012-01-01) One of the sources of the energy waste in wireless sensor networks is idle listening, the time in which a node monitors the free channel. In applications where the events occur sporadically, energy consumption due to idle listening can be further reduced by dual-radio cooperation. In dual-radio cooperation, nodes in the network have two stacks. One stack makes use of a low-power wake-up radio for event-driven communication over the main radio. The other stack may employ any sensor networking medium access c...
