CogMAC+: A decentralized MAC protocol for opportunistic spectrum access in cognitive wireless networks

The rapidly increasing number of wireless applications are making the wireless spectrum scarcity a serious problem. Cognitive MAC protocols have emerged as a promising solution to address this issue by opportunistically allowing secondary users to utilize unused licensed bands, and enabling spectrum co-existence of multiple secondary networks. In this paper, we present CogMAC + , a decentralize...

Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

Demo Abstract: A Decentralized MAC Protocol for Opportunistic Spectrum Access in Cognitive Wireless Networks

Cognitive MACs are becoming a reality for efficiently utilizing the constrained spectral resources. The spectrum opportunities are volatile and often difficult to predict. Furthermore, infrastructure based coordinated spectrum sharing is not a viable option for some applications and spectrum bands. Therefore, dynamic and decentralized medium access becomes highly desirable. We demonstrate a ful...

Evaluation of a BIBD Based Directional MAC Protocol for Wireless Ad Hoc Networks

The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...
