The focus of VANETs is to fulfil user's requirements on road side area which increases the safe and comfortable journey for users. It provides good communication like mobile ad-hoc network (MANET) when there is no intruders exist in the network. In VANET, communication depends on road safety such as emergency situation, vehicles tracking, messages monitoring and tracking of vehicles. But many attackers like black hole attack, wormhole attack and Sybil attack are more vulnerable to VANET. In order to provide efficient communication, we provide a malicious node identification routing mechanism which gives the valid route between two vehicles. To avoid several attacks, we introduce a protection mechanism that includes key management for preventing our network. Our proposed system provides efficient communication on VANET that focus on throughput, end-to-end delay, packet delivery ratio, detection rate and misdetection rate.

Privacy and security difficulties are primary concerns in VANET research as a result of the repeated vehicular movements, time-critical responses, and hybrid VANET architectures that differentiate these from other ad hoc networking types. Therefore, the design of secure mechanisms for authenticating and validating message transmissions between vehicles and eliminating adversarial elements from networks are of considerable importance in VANET research. This report offers a review of VANET features and security difficulties. The paper also summarizes certain chief threats to the authentication, confidentiality, and availability of secure services.

Hence, this obstructs the establishment of more consistent end-to-end communicating pathways and efficiently transferring data. Therefore, the VANETs display many network concerns and show differing security challenges for obtaining a secure communication, ubiquitous connectivity, and reputed management systems that can affect the cooperation and the negotiation between the various mobile networks. This survey report studies some techniques reported by the researchers for the detection of the Sybil attack in the VANET systems. Keywords: intrusion detection system, mobile ad hoc network, Sybil attack, vehicular ad hoc network

So it has same characteristics like wireless medium, dynamic topology, collision interference. Objective of VANET is to create and provide communications among group of vehicles without any central base station. An attack like Black hole in VANET is a main issue that degrades performance of whole network. Many existing algorithms tried to solve this issue but not completely. In order to solve above problems in VANET from black hole attack, we propose a new routing protocol named " Lifetime Improving Ad-hoc On-demand Distance Vector (LI-AODV) ". To reduce overload in routing process we introduce a scheduling algorithm named " Hybrid Round Robin with Highest Response Ratio Next (HRRHRRN) ". To prevent the network from Black hole attack we propose a new security algorithm called HMAC-SHA3-384 which is a combination of SHA3-384 and HMAC. This LI-AODV achieves better performance in lifetime of the network, reduces black hole attack, End-to-End delay, throughput, packet loss, Packet delivery ratio. Our experimental procedure provides efficient identification and removal of black hole attack in urban VANET.
