An Efficient Cooperative Mac Protocol for Wireless Lan
نویسنده
چکیده
In cooperative communication in wireless networks, selection of best relay node is an important task. And provide secure transmission is also a challenging work. Our proposed protocol provides a new approach for relay selection and secure transmission in cooperative network for wireless network. Secure and efficient relays are selected on the basis of RPI table that maintain RPI points which is calculated on the basis of behavior of the nodes in the network. Nodes behavior information is collected, calculated and maintained in RPI table. And CR of each node is generated. During the relay selection process, the CR of node and data rate is considered as a main selection criteria. As a result, our proposed protocol is secure, efficient and reliable for relay based cooperative communication in wireless networks.
