Bandwidth Constrained Priority Based Routing Algorithm for Improving the Quality of Service in Mobile Ad hoc Networks

A Mobile Ad-hoc Network (MANET), a self - configuring dynamic network for mobile nodes. The network is connected by wireless medium without the fixed infrastructure to form an arbitrary topology. It is used to propose a Bandwidth Constrained Priority based Routing Algorithm (BC-PBRA) to improve the Quality of Service (QoS) in the mobile network. The Development of the QoS constraint for routing protocol in MANET is a challenging task. As nodes are free to move randomly across mobile network, the routing protocols for MANET are prone to the node mobility. The best path has been chosen and QoS requirements are attained by the proposed routing protocol. Based on the priority allocated to the path, routing protocol estimates the bandwidth. In a queue based approach, packets are reached to the destination. This proposed bandwidth constrained Priority routing protocol increases utilization of bandwidth and decreases the delay of entire network. This work is carried out to show the result in Network Simulator (NS-2).
