simulation languages are created to simplify simulation development. But these languages are domain-specific and thus have to suffer from specialization. Nowadays, more and more simulations are developed by generic programming language. 3.4.1 MANETs / VANETs Simulation In this section, we sketch some famous MANETs/VANETs simulation. 3.4.1.1 Ns-2 Ns-2 [27] is a discrete event networks simulator written in a combination of C++ and OTcl, a Tcl script language with object-oriented extensions developed at MIT. Now, Ns-2 is the most widely used network simulator. It is originally designed to simulate wireless LAN protocols. With unremitting update, NS2 features a comprehensive model for simulating multi-hop wireless networks nowadays. It can support TDMA MAC protocol. 3.4.1.2 GloMoSim / QualNet GloMoSim [26] is a simulator designed for mobile wireless networks. It is written in parsec, a variant of C with parallel programming extensions. Further development of GloMoSim has been commercialized into the QualNet product (http://www.scalable-networks.com/) since year 2000. GloMoSim can support mobile wireless routing protocols, CSMA MAC protocols and UDP and TCP communication. GloMoSim is also adept at simulating of mobile IP networks. 24
3.4.1.3 TOSSIM / TOSSF TOSSIM [54] and TOSSF [55] are both simulators built on TinyOS. [11]. In particular, they are developed purposely to simulate the Berkeley MICA Mote hardware platform. They also can simulate any TinyOS applications. One flaw of TOSSIM is lack of a radio model. TOSSF tackles that limitation of TOSIM but it is not as accurate as TOSIM. They are very useful for debugging applications. 3.4.1.4 SWANS / JiST Different from above simulators, SWANS / JiST uses Java, a standard object-oriented language, to develop a new Java-based simulation framework. JiST is a discrete event simulation engine that features high throughput and automatic porting of application code to run in simulation time. SWANS is a scalable wireless network simulator built upon the JiST platform. SWANS is an application of JiST and create a simulation library. Apart from the simulators outlined above, there are also some famous and widely used MANETs/VANETs simulators. MATLAB, CSIM, OPNET and SHIFT[20]are the delegates among them. 3.4.2 Traffic Simulation Besides network simulations, a well-designed traffic simulation is also essential to successfully simulate VANETs applications. A few projects exist treating of traffic simulation. CORSIM [56] is one of the most widely used microscopic vehicle traffic simulations. As a microscopic 25
