Abstract: Our work mainly focused on the performance and effects of different mobility models like Random Waypoint, Reference Point Group, and Manhattan mobility models in different aspects to improve and analyze the behavior of Optimized Link-State Routing (OLSR), Temporally-Ordered Routing Algorithm (TORA) and Zone Routing Protocol (ZRP) routing protocols. These three routing protocols can be classified into the following three general categories, based on the timing when the routes are discovered and updatedproactive (OLSR), reactive (TORA) and hybrid (ZRP). In literature various researchers have discussed the performance issues in AODV, DSDV and DSR routing protocols in Random Waypoint mobility model on Mobile Ad hoc Networks (MANETs) is not satisfactory due to link failure and late acknowledgement. To resolve the specified issue, we have come up with other alternatives like Reference Point Group, and Manhattan mobility model and also other routing protocols like OSLR, TORA and ZRP. A simulation was carried out in NS2 and Bonnmotion for above said protocols and mobility models in Constant Bit Rate (CBR) traffic to analyzed using various metrics like packet delivery fraction, end to end delay and normalized routing load. In our simulation it was shown that few mobility model performed better in different routing protocols. In our simulation results, we got a high Normalized Routing Load for Random Waypoint compared to Reference Point Group, and Manhattan mobility model in both DRP and OSLR protocols
