SIR: a secure and intelligent routing protocol
for vehicular ad hocnetwork
Abstract— SIR: a secure and intelligent routing protocol for vehicular ad hocnetwork. Security in routing is an important issue in vehicular ad hoc network < Final Year Projects 2016 > to protect the valuable information. However, this intelligent transportation system (ITS) services provided by VANET are affected by the malicious vehicles. A secure and intelligent routing (SIR) protocol is proposed to transmit the data in a quickest path through the authenticated vehicles. Sending the data in a most connected path with less link connection problem enhances the system performance and selecting the authenticated vehicles in this quickest path protects the system from the malicious attacks. In this protocol, a weight W is calculated for every neighbouring junction Jneighbour by using the safety message transmission model, delay model, link connectivity model and vehicle position model. The Jneighbour with minimum W is selected as the junction through which the data are forwarded to the destination D. Simulation results show SIR performs better than secure path routing protocol, greedy traffic-aware routing, anchor-based street and traffic aware routing and geographic source routing protocols in terms of average end-to-end delay, network gap encounter and path length.
