A mobile ad hoc network (MANET) is a network consisting of a set of wireless mobile nodes that communicate with each other without centralized control or established infrastructure. Every node in MANET moves arbitrarily making the multi-hop network topology to change randomly at unpredictable times. The MANETs technique is being used widely in variety of applications. The most challenging factor in MANET is routing. In this review paper, we study the comparision of protocols in MANET for efficiency evaluation of mobility models (Random Way Model) like Ad hoc on demand Distance Vector (AODV), Dynamic Source Routing (DSR) and proactive routing protocol Destination Sequenced Distance Vector (DSDV). We study the effect of high mobility on the efficiency evaluation of these routing protocols with respect to Average End-to-End Delay (AEL), Normalized Routing Load (NRL), Packet Delivery Fraction (PDF) and Throughput. This helps to analysize the Random Way Model (RWM) on qualitative and quantitative metrics criteria. The results show that AODV shows better performance than DSDV, DSR. This imposes different design constraints and requirement on routing protocols for MANET. We have analyzed the efficiency of protocols by varying network load, mobility and type of traffic (CBR and TCP). The metrics used for performance analysis are Packet Delivery Fraction, Average end-to-end Delay, Routing Overhead and Normalized Routing Load. It has been observed that AODV gives better performance in CBR traffic and real time delivery of packet. Where as DSR gives better results in TCP traffic and under restricted bandwidth condition.
