Efficient channel utilization is the utmost challenge in mobile ad hoc network (MANET). Moreover, Medium Access Control (MAC) layer in MANETs experiences hidden and exposed terminal issues. During data transmission, there occurs increased energy consumption, overhead and many retransmissions because of the collision of Request To Send (RTS) packet. In order to solve this problem, we propose an algorithm named Fore-handed Collision Avoidance MAC (FCA-MAC). This protocol mainly focuses on the collisions detected at the destination. In FCA-MAC, the failed RTS packet detection is considered with Appeal for Request To Send (ARTS) packet. To reduce the delay, RTS collision and redundant re-transfer, we consider the minimum number of ARTS packets. To regulate the Contention Window (CW), an additional field factor named triumph factor is introduced in FCA-MAC which reflects the complete network state at the destination. Implementation of FCA-MAC is done using Network Simulator (NS2). Results reveal that the proposed FCA-MAC outperforms standard techniques with regard to various performance metrics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
