Effective admission control in multihop mobile ad hoc networks

Currently, quality of service (QoS) support for multihop mobile ad hoc networks (MANETs) is drawing more attention. Successful QoS strategies should consider the distinctive features of MANETs. In this paper, we propose and analyze an admission control mechanism, suitable for MANETs. We first propose two algorithms capable of estimating the available (to the mobile nodes) bandwidth. We then incorporate them in an admission control scheme, which allows dynamic allocation of the traffic. Performance evaluation shows that the proposed admission control mechanism is simple, yet effective in terms of maintaining the end-to-end delay below a certain threshold.
