Research Area:  Vehicular Ad Hoc Networks
In Vehicular ad-hoc networks (VANETs), routing and security are the mainchallenges. In our previous work, we have presented cluster-based secure communication with the certificate revocation scheme for securable communication between the vehicles.Cluster formation is done using the trust degree of each vehicle and this trust degree is calculated based on the direct and indirect trust degree of each vehicle. Information of eachvehicle is gathered by the corresponding cluster head (CH) in a cluster. This information is maintained by the Certificate Revocation List (CRL) in the Certificate Authority (CA). CA isolates a vehicle as an attacked node if it has less trust degree than the threshold trust value and it invalidates the certificate of attacked or revoked nodes. Before transmission, each vehicle in a cluster validates its certificate with the support of CA. After the validation, the other challenge of VANET i.e., efficient route is to be established so that Energy efficient enhanced OLSR routing protocol using Particle Swarm Optimization (PSO) algorithm is presented in this paper. After the establishment of the efficient route, the vehicle deploys the symmetric cryptography approach for securable transmission. Simulation results show that the performance of our proposed approach outperforms the performance of existing work in terms of energy efficiency.
