End-to-end delay is an important parameter in evaluating the performance of multihop ad hoc networks. To improve that, an efficient queue management scheme should be developed. Most existing queue management schemes do not take into account the number of hops that a packet traversed to reach its destination. In this paper, an efficient queue management scheme is proposed. The principal feature of the proposed scheme is to reduce the loss probability of the packets with large number of hops, by assigning more buffer space for those packets. This will lead to decrease the end-to-end delay and energy consumption. A Markovian model, is proposed to investigate the performance of the proposed scheme and to demonstrate that effective queueing scheme can improve the performance of ad hoc networks. The numerical results show that the proposed scheme outperforms the drop tail scheme in terms of end-to-end delay and loss probability.
