Title
ATMAC: adaptive token-based medium access control protocol for cognitive radio wireless mesh network.
Abstract
In next generation wireless communication, cognitive radio technology facilitates to utilize underutilized licensed frequency bands that help to enhance the spectrum utilization. Cognitive radio wireless mesh network CRWMN is a promising and reliable technology to experience high throughput with low cost. Existing IEEE 802.11 based medium access control MAC protocols offer high data rates with decreasing efficiency at the MAC layer. Hence, most of the researchers applied aggregation mechanisms to provide the solution to bandwidth craving applications. In CRWMN, MAC design is significant because stability, efficient resource utilization, and scalability are predominating problems; however, the specified MAC issues are not yet resolved. The proposed MAC is novel, which aims to ensure reliability and scalability for CRWMN. The common control channel is used to exchange handshaking frames between the transmitter and receiver. It helps us to schedule the data transmission as well as reserve the channel in a discrete time interval. It introduces a token-based channel accessing mechanism with resource-aware channel assignment, which resolves the problems of efficiency and stability. The proposed MAC simulated using the network simulator ns-2, and the simulation results demonstrate that the proposed protocol improved the performance compared with the existing protocols.
