TCP and UDP-based performance evaluation of proactive and reactive routing protocols using mobility models in MANETS

User datagram protocol (UDP) and transmission control protocol (TCP) are two popular transport layer protocols in infrastructure networks. The behaviour of these transport layer protocol with different mobility models and routing protocols is still not very clear. In this article, we have compared the performance of user datagram protocol (UDP) and transmission control protocol (TCP) in mobile ad hoc network (MANET) for optimised link state routing (OLSR), and temporarily ordered routing algorithm (TORA) routing protocols with different mobility models like random waypoint, reference point group, and Manhattan mobility models. We have done simulations in NS2 to analyse results using the performance metrics, such as throughput, packet delivery ratio, and end-to-end delay by for different types of data traffic and mobility models. The MANET performance is analysed under the effect of simulation time, number of nodes, and speed of mobile nodes. Our work indicates that TCP performs well for throughput in some mobility model and different routing protocols than UDP. The results presented in this paper clearly indicate that the different protocols behave differently under different parameters.
