An efficient Joint of Bandwidth Reservation and Routing Protocol for Mobile Ad hoc Networks

Abstract

In Mobile Ad Hoc Networks (MANET), during routing, problems may arise due to the end-to-end delay, mobility, intra-flow contention and frame collision. In this paper, we propose to design the bandwidth reservation and routing technique in MANET. In this technique, the available bandwidth is estimated based on the interference from both background traffic and traffic along the path. Then the bandwidth reservation is performed using the admission control technique. When the sink node wants to forward the data packet, it uses the bandwidth aware proactive routing protocol. It selects the forwarding paths to distribute the load based on the end-to-end available bandwidth. By simulation results, we show that the proposed technique enhances the packet delivery ratio and reduces the delay.
