VANET Analysis
Each participating vehicle is turned into a router or wireless node that can connect and become a part of the network in the range of 100 m to 300 m approximately. Network is dropped out in case vehicles fall out of the range. Any vehicles can join in the network, if it comes in the range to form a VANET. Each vehicle in VANET is considered as a mobile node which is proficient of communicating with its neighbours as well as with other vehicles within the network. The direct communication that takes place between onevehicle to another vehicle is called as Vehicle to Vehicle communication, whereas on the other hand, communication between a vehicle and an infrastructure, such as a Road Side Unit (RSU), is generally known as Vehicle-to-Infrastructure

One of the leading applications of VANET is in the critical medical emergency conditions where there is no infrastructure while it is critical to pass on the information for the security of human lives. However, along with these useful applications of VANET, emerge new challenges and problems. Non-existence of infrastructure in VANET lays added responsibilities on vehicles. Every vehicle becomes part of the network and also manages and control the communication on this network along with its own communication …show more content…
The OBU is mainly comprised of a resource command processor (RCP), and resources include a read/write memory employed to save and retrieve information, a user interface, a specific interface to connect with the other OBUs and a network device for short-range wireless communication on the basis of IEEE 802.11p wireless technology. The OBU connects to the RSU or to other OBUs via a wireless link and is held accountable for the communications among the other OBUs or with the RSUs. It can also accommodate a transmission service to the AU and transmits data in place of other OBUs on the network. The foremost purposes of the OBU in VANET are wireless radio access, ad-hoc and geographical routing, network jam control, secure information transmissionand information
