In asymmetric multihop wireless ad hoc networks the original medium access control protocol does not perform well, especially when the offered load is high. Many papers have studied this issues, and premeditated to obtain better fairness in multihop wireless ad hoc networks. These techniques provide some degree of fairness but either provide low throughput or assume MAC layer fairness and hence need improvements. In this paper we have proposed a new method based probabilistic control on round robin queue, and have obtained better results in terms of fairness. Our proposed method perform better than FIFO scheduling, RR scheduling, and PCRQ scheduling. For evaluating the performance of the proposed method, we have used Network Simulator version-2 (NS-2). Simulation results have shown that our proposed method produces higher degree of fairness.
