A new approach for supporting QoS in MAC layer over MANETs

Currently, the emergence of nomadic applications has raised intense research interest in providing quality of service (QoS) in mobile ad hoc networks (MANETs). An ad hoc network can be considered as an autonomous distributed system that consists of a set of identical mobile nodes that move independently and freely. Each node uses wireless links to communicate with other nodes that reside within its transmission range. In this paper, we propose a new approach for support QoS by the use of priority in the MAC buffer over MANETs. We evaluate the performance of our algorithm and compare its performance with the original IEEE 802.11b protocol. Simulation results show that this new approach reduces packet loss rate and increases throughput in the MAC layer.
