A Partial Bandwidth Reservation Scheme for QoS Support in Ad Hoc Networks

With the fast development of information technology, the application environment and multimedia services in Ad Hoc networks, all of these are needed to support QoS, and bandwidth is the one of key points needed to be considered. In this paper, we propose a partial bandwidth reservation scheme adapted to reactive routing protocol. In each node, it can estimate available bandwidth in real time, and introduce access control scheme to meet services QoS metric. Simulations integrated with DSR protocol show that this partial bandwidth reservation scheme proposed has improved network capability, and provided QoS support for network services in a certain extent.
