Abstract
Mobile Ad hoc Network is a network of independent nodes, which are mobile, connected through the wireless medium and highly dynamic by nature, and exemplified by the absence of physical infrastructure. The diversity and variations in wireless mobile devices are generating the revolutionary changes in the way users are using the services and resources for their purposes, at the same time it also poses many challenges to the researchers. In this paper, authors contribute toward the design of a new adaptive Quality of Service (QoS) paradigm for MANET. An honest attempt is made to develop an approach to decrease the overall delay, i.e. End-to-End delay and increase the efficiency of Protocol and also tried to make it more reliable by increasing the Packet Delivery Ratio (PDR) by applying Dijkstra Algorithm (for finding shortest and optimal route) and reducing queuing delay for increasing throughput by using a new hybrid algorithm. The modified AODV, which is named as Improved AODV (IAODV), enhance the “Packet Delivery Ratio” and reduce the “Queuing Delay”.

Summary
In modern times wireless networks have made great evolution towards mobile and wireless communication. MANET is basically a connectionless network with no centralized control, no fixed or a static infrastructure and high mobility [2]. It is a network with mobile routers which are linked through wireless links, the combination of which can form a capricious arrangement of nodes or a topology. Because of the insufficiency of any constant resources, i.e. fixed infrastructure, it is difficult to use already active routing protocol for MANET services, and it creates a number of confronting in ensuring the protection of the messages due to the clashes between the requirements of network security and the demands of mobile networks[3], refer to Fig 1. MANET does not require any fixed or permanent infrastructure to be deployed, for example, base stations, etc It is an alternative networking technology for connecting mobile devices expediently and impulsively [6]. In future time the technology gets popular and it will be the part of our day to day lives [9]
