Challenges faced by Medium access control (MAC) protocols for Wireless Sensor Networks (WSNs) include energy efficient operation and bandwidth limitations. Low duty cycle MAC conserves energy but at the same time it affects delivery ratio and latency. Use of multiple channels can improve the throughput and latency by alleviating the bandwidth limitations. This paper presents the design and performance...
In this study, a framework is proposed to stream different scalable videos from a base station to multiple secondary users over cognitive radio networks. The objective of this work is to ensure that the secondary users will enjoy continuous video playback with acceptable perceptual quality. To achieve such goal, a channel allocation algorithm is introduced to adaptively assign the available channels...
