Abstract-VANET is a form of Mobile Ad-Hoc Network or MANET and its different from MANET due to high mobility of nodes and the large scale of networks. The proposed location based service discovery protocols(LocVSDPs) will efficiently find services located in an RI (Region of interest) specified by the driver request using an efficient location-based request propagation mechanism and this protocol is make used in RTA (Regional trusted authority) will results in providing scalable network and also assist in reduction of number of packet lost in a network by which it resulting in efficient packet delivery ratio, throughput and overall bandwidth usage. The RTA method will help in improving the security purpose on network which also provides improvement in the performance of the resources on the system and save the bandwidth allocation of the vehicular networks. Keywords: VANET, RTA, LocVSDPs, Scalability. 1. INTRODUCTION 1.1. VANET VANET (Vehicular Ad hoc Network) technology is used to move cars as joint in network to make a transportable network. VANET turns every participating car into a wireless router or node, if cars fall out of the signal range and drop out of the network, other cars can join in so that a mobile Internet is created [1]. Some of the merits of Vehicular networks is to avoid congestion and finds better routes by processing real time. In road side, Departing vehicles will inform other vehicles about their departure on the highway and arriving cars can send warning messages to other cars traversing that intersection. Most of the deaths caused by crashing of cars are avoidable. Reduce (or avoid) traffic jam, Relieve driver effort, Decrease travel times Smooth traffic flow, Decrease Emissions of CO2, Noise etc [2].
light(EEBL),post crash notification(PCN), road hazard control notification(RHCN), cooperative collision warning(CCW),convenience applications includes congested road notification(CRN), parking availability notification (PAN), commercial application includes remote vehicle personalization / diagnosis (RVP/D) [4], Service announcement (SA), content map database download (CMDD).Cooperation among vehicular networks must be introduced into transportation networks to improve overall safety and network efficiency. Few challenges faced by VANET are Scalability: if number of vehicles on the road side increases, Reliable communication: vehicular network provide communication with the help of multi hop transformation of information by which it tremendously extend the network operators from fixed infrastructure to virtual infrastructure as a result of this reliable communication is a major challenge, Security and privacy: are major concerns in the development and acceptance of services. In our paper we mainly focus on two challenges namely (scalable and security) and besides donate solutions for convalescing those dispute in VANET. RTA (regional trusted authority) generates cryptographic key materials for the RSUs and the vehicles in its region,
VANET mainly aims to provide intelligent transportation systems [3].VANET provides safety application which includes slow/stop vehicle advisor(SVA),emergency electronic brake and delivers these keys to them over secure channels. It manages a list of the vehicles of which participations have been revoked, updates the list periodically, and advertises the list to the network to isolate the compromised vehicles. Our paper presents in section 2 an overview on VANET structure, section 3 we described major difference in our existing
