A Survey on MAC Protocols for Wireless Sensor Networks and Cognitive Radio Sensor Networks Design
Wireless Sensor Networks (WSNs) has been a wide research topic for more than a decade. Typically, a WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions. These sensors generate report over the network on the occurrence of any event. For a WSN to provide better reliability and improved lifetime, an efficient Medium Access Control (MAC) protocol design holds a paramount importance. Several multi-channel MAC protocols exist which performs better than the single channel protocols.
