Abstract

Very prestigious work has been performed in the field of mobile ad hoc networks (MANETS) with respect to their routing protocols. Researchers have developed and designed so many protocols for these networks, but due to the dynamic change in topology, decentralization, power management, bandwidth and many other factors like these no specific routing protocol is exclusively recommended, up to today, which comply and fulfill all the needs and requirements of users for ad hoc networks in all situations of network variation statuses and traffic overhead. This paper contributes an effort towards anthology of one of the major segment of routing protocols i.e. unicast, their categories and the main type of unicast routing protocols such as DSDV from proactive plus DSR from reactive. The protocols and their performances are evaluated on the basis of some metrics commonly used in support of simulation environment for getting simulation results acquired by simulation of certain model with some parameters with the help of NS-2, OPNET and GloMoSim like simulators. The performance evaluations are declared on the basis of those simulations results, but all the results peter out when magnitudes of those attributes or load of network changes (increased or decreased) with respect to bandwidth, power management, end to end delay, data errors, packet dropping ratio or even with distance. Here in this paper we have scrupulously reviewed the work done on these protocols and majority of the simulated results are examined and finally suggest few common uniqueness and differences with respect to their properties which remain unchanged in all the situations and scenarios.
