Abstract

The invention discloses an unmanned aerial vehicle ad hoc network DSR protocol optimization method based on a firefly algorithm, and t. The method comprises the steps: receiving an initialized routingrequest transmitted by a source node in a broadcast mode through a neighbor node, and calculating a corresponding fitness function value and a corresponding comprehensive fitness value according to the energy consumption, movement speed, transmission loss and congestion rate; acquiring an initial firefly position, initializing luminous intensity, and performing discretization movement based on amovement formula; mappingthe moved fireflies are mapped to the corresponding unmanned aerial vehicle nodes; correspondingly adjusting the position and the luminous intensity of the firefly are correspondingly adjusted; until the firefly reaches a specified node or the number of iterations reaches an iteration threshold.; Aaccording to the method, the unmanned aerial vehicle node with high fitnessis comprehensively selected as the next hop node of the transmission path, so that the stability of the transmission link is improved, the survival time of the path is prolonged, the service receivingrate is improved, the end-to-end time delay is reduced, the routing overhead is reduced, and the overall performance of the unmanned aerial vehicle ad hoc network is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle ad hoc network, in particular to a method for optimizing the DSR protocol of the unmanned aerial vehicle ad hoc network based on the firefly algorithm. Background technique [0002] UAV Ad Hoc Network (UAV Ad Hoc Network) is a wireless network based on flying drones, and the drone nodes in the network act as transceivers and routers. Due to the dynamic and unpredictable topology of the UAV Ad Hoc Network, how to find and establish a relatively reliable path to transmit services in the UAV Ad Hoc Network whose topology is unpredictable is an urgent problem to be solved for the UAV Ad Hoc Network . Ad hoc network routing protocols need to meet the requirements of communication service quality on UAV nodes with limited power and limited bandwidth, adapt to rapid changes in network topology, and at the same time reduce the routing overhead of maintaining the network as much as possibl...
