Chapter 4 MAC Protocol for CRSN
نویسندگان
چکیده
Cognitive Radio (CR) technology has gained popularity in Wireless Sensor Networks (WSN) because of scarcity caused by the increase in number of wireless devices and service, and it provides spectrumefficient communication for the resource constrained WSNs. However, appropriate protocols have to be devised to satisfy the requirements of both WSNs and CRs and to enjoy the benefits of cognition in sensor networks. In this chapter, the authors review the existing schemes for wired, wireless, and cognitive radio networks. In addition, they propose a novel energy-efficient and spectrum-aware Medium Access Control (MAC) protocol for the cognitive radio sensor network. The authors design a spectrum-aware asynchronous duty cycle approach that caters to the requirements of both the domains. The performance of the proposed MAC is evaluated via simulations. Performance evaluations are also compared with MCMAC, a multi-channel MAC for WSNs. The comparative results show that the proposed scheme outperforms the multi-channel scheme for WSN.
