IntroductionVehicular Ad-hoc Networks (VANETs) are created by applying the principles of Mobile Ad-hoc Networks (the spontaneous creation of a wireless network of mobile devices) to the domain of vehicles. VANET is a technology that uses moving vehicles as nodes for creating mobile networks. VANET can create a wide range of networks by changing every vehicle into a wireless node and allowing cars to connect to each other that are 100-300 metres apart. VANETs were first mentioned and introduced in 2001 under "car-to-car ad-hoc mobile communication and networking" applications, where networks can be formed and information can be relayed among cars. It was shown that vehicle-to-vehicle and vehicle-to-roadside communications architectures will co-exist in VANETs to
