Design method of joint routing protocol for UAV communication network

Abstract

The invention provides a method for designing a joint routing protocol of an unmanned aerial vehicle communication network, and belongs to the technical field of designing the routing protocol of the unmanned aerial vehicle communication network. The method comprises the following steps: firstly constructing a lightweight unmanned aerial vehicle forward queue model that is low in maintenance cost and is easy to achieve; then based on the model, separately extracting an instant queue power concept and an instant transmission power concept, and designing a joint routing decision in a sum form; designing a new data packet header, adding unmanned aerial vehicle information to the data packet header, opening the monitoring mode of the unmanned aerial vehicle, and passively discovering a neighbor unmanned aerial vehicle; and finally selecting a proper unmanned aerial vehicle to serve as the next hop according to the maximum routing decision variable, and transmitting data packets to the next hop unmanned aerial vehicle. The joint routing protocol of the unmanned aerial vehicle communication network has a smaller node queue maintenance cost and a lower neighbor unmanned aerial vehicle discovery cost, and efficient communication access services can be provided for short time bursty traffic on the ground.
