aMAC: Advanced MAC Scheme for Mobile Ad-hoc Networks

Abstract

A new medium access control (MAC) scheme for mobile ad-hoc networks (MANETs) has been proposed with the goal of achieving fairness at the MAC layer. Most of the recently proposed contention-based MAC for MANET still use binary exponential backoff (BEB) algorithm to solve the contention problem, which contributes partially to instability and unfair medium sharing. In this paper, we propose to combine the exponential increase exponential decrease backoff algorithm (EIED) with an existing MANET MAC called fair MAC with cooperation between sender and receiver (FMAC/CSR), aiming to achieve fairer medium sharing between contending connections and more stable behavior. Preliminary simulation results show that our scheme outperforms existing MAC schemes, with respect to stability and fairness
