Location Verification and Stability with Trust Management for Avoiding Malicious Vehicles in Geographic Routing for VANET

The largest ad-hoc network comprising Vehicular ad-hoc networks (VANET) is believed for providing utmost safety and comfort to the users including (passengers and drivers). However, deployment of such revolutionary technology on very large scale is a major challenge in designing security of the system with, its protocols and applications. Short contact times between different mobile nodes that generated due to lack of large number of vehicles or ideal radio environment obstructing the path of radio transmission and sheer the network size are considered to cause more challenges. Network management no longer depends on ubiquitous infrastructure access but it relies on infrastructure independent operation. These limitations of the network infrastructure make the design of security mechanisms very challenges. This paper proposes a location verification and stability with trust management based geographic routing protocol for highly dynamic and unsecured vehicular network, named as “Location Verification and Stability with Trust management for avoiding malicious vehicles in geographic routing for VANET”. This protocol defined the misbehaving vehicles can produce wrong information about their actual location. And also, the malicious vehicles can drop packets that they need for forwarding toward the destination. This work propose a location verification technique to address the attacks of falsifying location and find for trust based stable multi-hop path routing, aiming to defeat attack at the time of data forwarding. This process improves the reliability of routing packets significantly.
