Relay Selection on Co-operative Communication using MAC Network coding

Abstract

This work, proposed a network coding aware utility based relay selection strategies, to choose the best relay in an efficient and distributed manner. Focus on the MAC layer protocol design which is critical to reap the performance gains brought from the physical layer. Use of NCAC-MAC protocol in wireless ad hoc networks increases the throughput and reduces delay. The conventional Acknowledgement (ACK) frame and Negative ACK (NACK) frame a new control frame named Eager-To-Help (ETH) is introduced in this schema to enable the efficient and distributed best relay selection.
