Security Enabled Junction-Based Multipath Source Routing Algorithm for VANETs

Junction Based Multipath Source Routing Algorithm(JMSR) is a geographic routing protocol, in the sense that it exploits the location of the nodes and also of the street junctions, known via digital street maps. JMSR is characterized as junction-based because it is a geographic or position-based routing protocol, where the junctions’ positions are of much higher importance than the positions of the nodes themselves. The disadvantage of JMSR is that it does not specify how routing happens in presence of a malicious node. An improvement of JMSR is proposed through this paper. In this paper a method is discussed to deal with malicious nodes in VANETs.
