A Collaborative Routing Protocol for the Internet of Drone Things in the VANET Environment

Vehicular Ad-Hoc Network (VANET) is a highly emerging technology in the intelligent transmission system. Its special features such as high speed, random topology, and recurrent change in topology lead to ineffective communication in VANETs. To overcome such drawbacks drones are introduced in VANETs and to achieve effective communication routing needs to get improved. So that it is possible to protect the VANETs from delay, overhead, and link failures. In this paper, a Multipath Routing Protocol for Collaborative Internet of Drone Things (MRP-CIoDTs) is proposed to improve communication stability during data transmission between the source and the destination. The major segments of the proposed protocol are Zone based AOMDV (Z-AOMDV) routing protocol, Zone based spatial coverage, and mobility models. Through the Z-AOMDV protocol, the best intermediate hops are chosen for data transmission between the source and the destination. In case link failure happens immediately through drones the data gets transmitted. Through zone based spatial coverage model the selection path is validated and finalized. Finally, communication is initiated using the determined mobility models. Through this process, the delay and overhead can be reduced. The proposed MRP-CIoDTs is implemented using OMNET++ and the parameters that are considered for the performance analysis are computational overhead, throughput, packet delivery ratio, and computational delay as well as it is compared with the earlier approaches such as NRCLM and DPUAV. From the outcome, it is understood that the proposed MRP-CIoDTs achieved low computational delay and overhead as well as achieved high packet delivery ratio and throughput when compared with the earlier methods.
