Traffic and mobility models play an important role in evaluating the performance of these communication networks. Despite criticism and assumption from various researches on Transmission Control Protocols (TCP), weaknesses on Mobile Ad Hoc Network (MANET), and Vehicular Ad Hoc Network (VANET). A simulation was carried out to evaluate the performance of Constant Bit Rate, Variable Bit Rate and Transmission Control Protocol on MANET and VANET using DSR routing protocol. CBR, VBR, and TCP have different manufacturer operation mechanisms and these differences lead to significant performance of CBR and VBR over TCP with better throughput and less average maximal end-to-end delay. DSR was able to respond to link failure at low mobility which led to TCP’s performance in packets delivery. INTRODUCTION Mobile Ad Hoc and vehicular ad hoc networks plays a vital role within the field of network com- munication. The recent developments in wire- less technologies have made Vehicle-to-Vehicle communication (V2V) and Roadside Unit (RSU) achievable in mobile ad hoc networks. This has given birth and brought a new concept of Mobile Ad Hoc Wireless Network known as the vehicular ad hoc network. Vehicular Ad hoc Networks are self-organizing communities of wheeled mobile units consisting of large number of vehicles and a small number of fixed infrastructure nodes Lawal Bello University of Greenwich, UK Panos Bakalis University of Greenwich, UK
