Enhancing the security of routing in vehicular ad hoc networks using meta heuristic optimization techniques

Abstract

The prodigious intelligent transport systems and the growth in newlineomnipresent internet connection led to numerous research and improvements newlinein vehicle Ad Hoc networks (VANET). VANET is able to transmit, receive, newlineand exchange information among cars, roadside units (RSUs), cellular towers newlineand enable security applications such as collision prevention, lane changes, newlinepublicity and emergency alerts. However, this dynamic network is restricted newlineby vehicle speed and frequently causes bandwidth breakages and waste. The newlinedistribution of routing and bandwidth should thus be seen as hard concerns. newlineThe performance of the network actually depends on how effectively packets newlineare transported between cars and the distribution of capacity. The main newlineobjective of the research is to improve safety of transportation vehicle based newlineon inter vehicular communication. Safety is one of the most significant concerns with VANETs as the transmitted information is dispersed in an open access environment and newlinetherefore poses a major challenge to VANET. Effective safety techniques in newlineVANETS are a demanding problem nowadays. If cars communicate in a newlinenetwork, messages received from other vehicles for validation and acceptance newlineshould be verified. With their unique information from the Electronic License newlinePlate, the networked cars may be identified and helped to identify themselves newlinein the network. The use of their original identities might provide the network newlinean opportunity for attackers. Novel techniques to ensure safety and trust newlinebetween nodes are therefore a challenging aspect. The major objective of this newlinestudy is to explore safety techniques for trustworthy communication within newlinethe Ad Hoc Vehicle Network. One of the most important problems is the packet delivery ratio for VANET routing. Arrangement in VANET depends on several attacks on newlinesecurity. The various attacks during the compromising period in the VANETs newlineare done by estimating the drop rate of the packet along with its output. newlineAddressing this problem, an Advanced Secured Routing Algorithm (ASRA) newlineis
