Energy Efficient Mac Protocol with Fair- Scheduling Technique in Manet

In Mobile Ad hoc Networks (MANETs), achieving fairness and increasing channel utilization are the important design goals of scheduling. However, these two goals contradict with each other. In this paper, a fair-scheduling technique for inelastic traffic flows in MANET is proposed. The network traffic is differentiated into two categories as elastic and inelastic flows. In this technique, data packets of inelastic flows are prioritized over data packets of elastic flows. Utility function is estimated for considering channel utilization and channel state information along with delay of data packets. When more than a data packet of inelastic flows compete in scheduling, packet with high (upper bound) on delay field is prioritized and scheduled. The proposed technique is validated through simulation results. It is proved that the proposed technique offers fairness in scheduling network traffic.
