Advances in wireless communication technology and the proliferation of mobile devices enable the capa-udbilities of communicating with each other even in areas with no pre-existing communication infrastructure.udTraffic and mobility models play an important role in evaluating the performance of these communicationudnetworks. Despite criticism and assumption from various researches on Transmission Control Protocolsud(TCP), weaknesses on Mobile Ad Hoc Network (MANET), and Vehicular Ad Hoc Network (VANET).udA simulation was carried out to evaluate the performance of Constant Bit Rate, Variable Bit Rate andudTransmission Control Protocol on MANET and VANET using DSR routing protocol. CBR, VBR, and TCPudhave different manufacturer operation mechanisms and these differences lead to significant performanceudof CBR and VBR over TCP with better throughput and less average maximal end-to-end delay. DSRudwas able to respond to link failure at low mobility which led to TCP’s performance in packets delivery.ud
