Self-Organized Multi-Hop Bridge Reservation Medium Access Control for Cyber Physical Autonomous Vehicles

The cyber-physical intelligent systems (CPIS) are integrated with internet-connected network devices for communication and content sharing. The CPIS is widely used in intelligent transportation and unmanned ariel vehicle. In an autonomous cyber-physical vehicle system to coordinate and connect with the other vehicle to enhance the perception is a challenging task. The ad-hoc network of nodes should be well connected with the control unit and other authorization entities for dropping less transmission. Mostly the ad-hoc vehicle suffers from connectivity issues whenever the handover from one network into another network. The current self-organized vehicle suffers in terms of hard and soft handover because of its dynamic nature. The proposed approach is named Multi-hop Bridge Reservation Medium Access Control (MBR-MAC) for optimal handover between the roadside unit. The approach MBR can handle hidden and exposed terminal problems. Mostly the failure handover happens when there is no channel to carry over the current connectivity. The proposed scheme utilizes the time and code division multiplexing for optimum bandwidth utilization. The experimental result shows the better results in terms of byte transmission rate and handover failure rate.
