Fortification of QoS routing in MANETs using proactive protocol

An adhoc network is a collection of mobile nodes connected by a wireless link, where each node acts as a router. In order to facilitate the communication within the network, a routing protocol is needed. Due to bandwidth constraint and dynamic topology of the mobile adhoc networks supporting quality of service (QoS) is challenging task. The aim of this work is to present QoS enabled routing protocol in adhoc networks and compare it with normal routing protocol. The optimized link state routing (OLSR) protocol is an optimization of the classical link state protocol, which is used for implement the QoS. Such protocol is adopted for the reason that it reduces the size of control messages and minimizes the overhead from the flooding of control traffic. The performance of both routing and QoS routing protocols are evaluated using network simulator Ns-2.QoS enabled routing protocol shows a significant improvement in protocol performance metrics applied in our measurements, such as packet delivery ratio, packet loss and delay.
