A mobile ad hoc network (MANET) is a self-constructing network of wireless devices connected by wireless links without any infrastructure. Every device that is involved in a MANET simulation is free to move independently in any direction of its choice. MANET nodes mounted on moving vehicles, wearable devices & as personal medical devices are showing significant applications in the field of ubiquitous healthcare. Performance of MANETs largely depends upon the routing mechanism & nature of mobility. The aim of this paper is to analyze the performance of various Manet routing protocols. Two reactive protocols (AODV, DSR), a proactive protocol (OLSR), a hybrid protocol (ZRP) have been evaluated by considering the Random walk mobility model. Simulations are carried out using OPNET simulator to evaluate the performance on the basis of throughput, Media access delay, and network load and retransmission attempts. Our experimental results show that ZRP protocol has optimized results as compared to other protocols.
