Analysis of Various Trust based Security Algoithm for the Vehicular AD-HOC Network

Abstract

Due to the exponential growth in the automobile industry and road transport, there is need of intelligence transportation system (ITS). Vehicular ad-hoc is a part of intelligence transportation system (ITS), which provides security, traffic efficiency and ease to the user. In Vehicular network various nodes exchange the messages and data for the communication. For transmitting the data from source to destination node, we have to rely on intermediate nodes due to limited range of the vehicular nodes. To check the reliability of data delivery we have to find out that which node is trustable or which node is faulty. There are various algorithms presents by various authors to compute the trust of different-different nodes presents in the network. Trust based algorithms are easy to implement and requires very less calculation overhead.The authors have studied and analyzed various trust based security algorithms in terms of approach and tools used by different authors. The different attacks and the limitations of the various trust based security algorithms are briefly summarize in table-1. Further authors have compiled in table-2 the attacks with targeted services and possible solutions. The various simulation tools used to simulate the vehicular ad-hoc network are summarized in table-3. The paper is useful for the bingers who wish to carry out further analysis on trust based security algorithms for vehicular ad-hoc network (VANET).
