Intelligent Greedy Perimeter Stateless Routing Scheme for Unmanned Aerial Vehicles

The dynamic behavior, rapid mobility, abrupt changes in network topology, and numerous other flying constraints in unmanned aerial vehicle(UAV) networks make the design of a routing protocol a challenging task. The data routing for communication between UAVs faces numerous challenges, such as low link quality, data loss, and routing path failure. This work proposes greedy perimeter stateless routing(GPSR) based design and implementation of a new adaptive communication routing protocol technique for UAVs, allowing multiple UAVs to communicate more effectively with each other in a group. Close imitation of the real environment is accomplished by considering UAVs’ three-dimensional(3 D) mobility in the simulations. The performance of the proposed intelligent greedy perimeter stateless routing(IGPSR) scheme has been evaluated based on end-to-end(E2 E) delay, network throughput, and data loss ratio. The adapted scheme displayed on average 40% better results. The scenario has been implemented holistically on the network simulator software NS-3.
