DOSP: Data Dissemination with Optimized and Secured Path for Ad-hoc Vehicular Communication Networks

Timely delivery of critical information and data may reduce the chances of road accidents using vehicular adhoc networks. The vehicular ad-hoc network uses the multihop data dissemination technique due to the limited transmission capabilities of the vehicles. The dynamic topology of the network due to the presence of highly mobile vehicles experiences frequent path disconnections in the communication network. Due to these challenges, the timely delivery of messages to the intended recipient is still a challenging issue. The core attention of this work is to report the timely message delivery problem in the vehicular communication network. In this work, we proposed a secure and optimized data routing technique using cross-layer optimization for the heterogeneous ad-hoc network. Firstly we calculate the trust value of nodes based on the entity-centric trust model. Further, we estimate the link durability and probability of collision in the network of vehicles. Our prime aim is to increase the link reliability and duration to deliver the message on time. We also minimize the probability of data collision and improve the delivery ratio of the network. The proposed optimized data dissemination model has been tested with several network parameters. The experimental results show significant improvements in terms of minimized delay, packet loss ratio.
