Abstract

In mobile ad hoc networks (MANET), achieving QoS guarantees by over-provisioning of the resources is typically infeasible because in these networks, the overall available bandwidth is quite limited. In this paper, we propose an optimal bandwidth allocation technique in IEEE 802.11e MANET. In this approach, initially available bandwidth is estimated using the bandwidth probing technique. The estimated available bandwidth is shared in reserved and shared region by the bandwidth sharing scheme for the real-time and non-real time flows respectively. The bandwidth allocation policy allocates additional bandwidth from the reserved region of available bandwidth, when the mobile host needs additional bandwidth for real-time flows. In case of excess bandwidth utilization of mobile hosts, the excess bandwidth is restored to the shared region of available bandwidth thus minimizing the reserved region.. By simulation results, we show that the proposed approach offers optimal bandwidth for MANET
