Abstract
Abstract: A VANET is a decentralized network as every node performs the functions of both host and router. The main benefit of VANET communication is the enhanced passenger safety by virtue of exchanging warning messages between vehicles. VANET differs from MANET as it provides higher mobility of nodes, larger scale networks, geographically constrained topology and frequent network fragmentation. This paper presents a detailed survey of trust management in VANETs. The paper consists of various ways for achieving trust in vehicular communications. Trust establishment is a major challenge in vehicular ad hoc networks as the outcome of the trust establishment process is a trusted relation between nodes. In critical applications like hazard warning a receiving node needs to ensure authenticity and trust-ability of received messages before reacting to them. Different trust establishment techniques exists each of them satisfies various properties such as scalability, privacy, intrusion detection, access control. Trust establishment may be decentralized, behavior-based, or certificate-based. Thus the aim of Trust management is to improve the security and reliability in VANET communications.
