Multichannel sensing scheduling and interference avoidance are two major challenges for medium access in Cognitive Radio Networks (CRN). In this paper, we propose an adaptive sensing cycle scheme for scheduling multichannel sensing with interference avoidance in CRN. The principle of the proposed adaptive sensing cycle scheme is to prioritize the multichannel sensing and access based on interference...
Wireless mesh infrastructure provides for attractive solutions to telecommunication services, where larger network capacity for broadband wireless Internet may be realized by spatial spectrum re-use, and lower network costs may be realized by the saving of cable/fiber backhaul on wireless stations. However, state-of-the-art technologies suffer from scalability limitations, where dataflow quality of...
State-of-the-art research and development in large-scale wireless systems have been pushed to the limits, essentially on dealing with the challenges from network scalability and node resource (complexity) constraints, as well as the need for an effective application programming interface. In this paper, we present the reference model of Embedded Wireless Interconnect (EWI), as a potential merge of...
Here is to propose a demonstration of opportunistic wireless mesh networks for broadband wireless Internet access, supporting real-time services, e.g., of voice and video. The enabling technology is of the large-scale cognitive networking, which opportunistically utilizes network resources including both spectrum bandwidth and mesh radio (station) availability. We further demonstrate that: (1) vast...
