Abstract: Mobile Ad-hoc network is a self configuring wireless network. It does not have any fixed infrastructure. Mobile node can leave and join the network. Therefore network topology changes any time. In Manet hosts can work as a router and forwards data from initiator to receiver. Since wireless channel is shared and topology is dynamic, providing quality of service (QoS) is a challenging task. QoS routing can find optimal routes that supports QoS requirement based on the received information during route discovery process. If QoS requirement cannot be supported, the admission control mechanism reject incoming request. Bandwidth estimation is a technique to determine available data rate on a route in the network. The term bandwidth means data rate not the physical bandwidth in hertz. QoS routing is required because most of the real time applications depend on the network’s condition. QoS in terms of bandwidth ensures transmission of real time data. In this paper a new bandwidth estimation method EAB (enhanced available bandwidth) is proposed. The performance of EAB-AODV is compared with AODV. The performance of EAB-AODV is better than AODV in terms of bandwidth.
