Secure and Reliable Routing Protocols for VANETs

VANETs stands for vehicular ad hoc networks which is a new technology and works for vehicles. The main aim of this technology is to provide security or safeness which is applicable to all those persons who are sitting in vehicles. VANETs are applicable for providing communications amid vehicles without any necessity of determinate infrastructure. VANETs are useful for providing information amid vehicles because it is not necessary that drivers are aware during the time of driving. It is very difficult to implement an expeditious routing protocol amid vehicles due to propellant features of vehicular environment. The nodes which are used in VANETs have rattling advanced mobility. To reach the final destination, there are plenty of challenges for routing the packets. It creates ambitious technical contents due to prevalent refinements of network topology which is necessary to tackle efficiently. One of the major critical contents is the routing infallibility. End to end of this paper, the main aim is that the researchers and developers could take hold the most disputes and endeavors of the routing protocols by taking the benefits of information. They can take hold in such a way for improving their lustiness and reliability in VANETs. This article has a brief summary of all the routing protocols which are used in VANETs. This paper will be also helpful in elaborating the demerits and demerits of the active routing protocols. It will give a detailed depiction about the different active routing techniques. A detailed depiction will be provided in connection with some merits and demerits and different constraints. In this paper, comparison of all the active routing protocols are also defined which is based on their speed, conveyance, PDR, quantifiability and feasibleness.
