conceptual simulation, CORSIM traces and represent individual action of each vehicle [13]. Bonn-Motion [57] can generate simple vehicle movement patterns that are used as trace files in network simulators. Vissim [58] provides an implementation to approximate urban vehicle movement using a microscopic simulation approach. It is developed by Java language. SUMO [59] is designed to provide a common platform for testing and comparing models of vehicle behaviour, traffic light optimization, routing etc. it is written by usage of the standard C++. SUMO exploits microscopic, space-continuous and time-discrete car-following model to implement vehicle movements. STRAW [60] is built upon JiST/SWANS network simulation. It provide a vehicular mobility model by usage of map data for real US cities and limit their mobility according to vehicular congestion and simplified traffic control mechanisms. 26
Chapter 4 DESIGN After covering much of the background research, we have already analyzed and compared various existing communication protocols and a variety of simulation works. From this chapter we start to develop a VANET environment simulation and then build a TBMAC protocol simulation on top of the implemented VANET scenario. This chapter aims to describe the design architecture as well as to provide the details of each architectural component. We also compare and contrast diverse simulation approaches and then pick up the appropriate approaches. Moreover, we shall exhibit the corresponding design issues behind the approach selection. 4.1 Introduction Performance evaluation is a crucial part of designing and validating new protocols in the computer and communication fields. In [35] the authors state that a realistic mobility model in an appropriate level of detail determines the accuracy of network simulation results. For that reason, in this project the most important challenge is to create a traffic simulation that accounts for individual vehicular motion and the circumstance of radio transmission cell so as to perform the TBMAC protocol in a simulated VANET environment. 27
