Abstract | A mobile ad-hoc network (MANET) is a collection of self configuring mobile devices, connected through wireless physical medium without having any fixed infrastructure. MANET technology is highly important in the emergency communication scenarios like post disaster rescue operations, military operations instant communications such as meetings and conferences. In the field of packet-switched communication networks, the term quality of service (QoS) refers to a guaranteed network data performance level. Real time applications like VoIP (Voice over IP), IP Television are QoS sensitive and need to guarantee a certain level of performance. AODV is a purely on demand MANET routing protocol. It creates high latency for connection set up and has no provision for QoS guarantees. In this thesis, the route discovery process of AODV has been modified to reduce the connection set up latency and it has been named as NQoS AODV. QoS provisioning based on delay and bandwidth requirements has been incorporated in NQoS AODV to ensure guaranteed performance level to the QoS sensitive applications. Four performance parameters: End-to-end average delay, packet delivery ratio, throughput and control overhead have been considered to compare the performance of the two protocols. From the simulation results, we found that the proposed NQoS AODV performance almost same as traditional AODV under low traffic, but it outperforms AODV in all respect for high traffic load |
