Asymmetric encryption based secure and efficient data gathering technique in VANET

Abstract

Data gathering is big challenging problem in Vehicular ad hoc Network (VANET). To overcome this problem, plenty of data gathering techniques have been proposed. None of the technique provides security in the process of gathering of data from vehicles to RSUs. The primary objective of this paper is to propose a secure as well as efficient data gathering technique that provides security and confidentiality to the gathering of data from vehicles to RSUs and vice versa. Performance of the data gathering technique proposed is evaluated by comparing the proposed technique with the existing data gathering techniques on the basis of message delivery ratio (MDR), average delay and computational overhead. Results of simulation assure that the data gathering technique proposed performs better in comparison to existing data gathering technique.
