Mobile Ad-Hoc Networks (MANET) are becoming an emanating technology among mobile devices. It is a structure less network of independent collection of wireless mobile nodes [Smart phones, Laptops, iPads, PDAs, Sensors etc.] connected by wireless links. Routing in Ad-hoc networks is challenging due to mobility of nodes and dynamically changing topology. The primary objective of the routing protocols is to establish an optimal and efficient route between the communicating nodes. Due to different network environments like varying number of nodes, speed, network load, it is difficult to figure out which routing protocol may perform well. This study investigates the performance and behavior of MANET routing protocols such as DSDV, AODV, NCPR and ZRP with a special focus on their comparison, functionality and issues. In this review, we analyzed about the protocols based on various quantitative parameters such as average throughput, packet delivery ratio, routing overhead and average end to end delay.

Energy and latency are the significant Quality of Service parameters of ad hoc networks. Lower latency and limited energy expenditure of nodes in the ad hoc network contributes to a prolonged lifetime of the network. Reactive protocols determine the route to the destination using a route discovery process which results in increased delay and increased energy expenditure. This paper proposes a new technique of route discovery, Dynamic Blocking Expanded Ring Search (DBERS) which minimizes time delay and energy required for route discovery process. DBERS reduces energy expenditure and time delay occurring in the existing route discovery techniques of reactive protocols. The performance of DBERS is simulated with various network topologies by considering a different number of hop lengths. The analytical results of DBERS are validated through conduction of extensive experiments by simulations that consider topologies with varying hop lengths. The analytical and simulated results of DBERS are evaluated and compared with widely used route discovery techniques such as BERS, BERS+. The comparison of results demonstrates that DBERS provides substantial improvement in time efficiency and also minimizes energy consumption.
