Abstract

The invention discloses a DSR protocol optimization method for unmanned aerial vehicle ad hoc network based on the firefly algorithm. The neighbor node receives the initialized routing request sent by the source node in the form of broadcast, and according to the energy consumption, moving speed, transmission loss and congestion calculate the corresponding fitness function value and comprehensive fitness value; obtain the initial firefly position and initialize the luminous intensity, and do discretized movement based on the movement formula; and map the moved firefly to the corresponding UAV node, And correspondingly adjust the position and luminous intensity of the firefly until the firefly reaches the designated node or the number of iterations reaches the iteration threshold, the method of the present invention comprehensively selects the UAV node with high adaptability as the next hop node of the transmission path, and improves the transmission chain. The stability of the path prolongs the survival time of the path, improves the service receiving rate, reduces the end-to-end delay, reduces the routing overhead, and improves the overall performance of the UAV Ad Hoc Network.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle ad hoc networks, in particular to a DSR protocol optimization method of unmanned aerial vehicle ad hoc networks based on firefly algorithm. Background technique [0002] UAV Ad Hoc Network is a wireless network with flying UAV as the carrier, and UAV nodes in the network act as transceivers and routers. Since the topology of the UAV ad hoc network is dynamic and unpredictable, how to find and establish a relatively reliable path to transmit services in the UAV ad hoc network with unpredictable topology is an urgent problem to be solved in the UAV ad hoc network. . The ad hoc network routing protocol needs to meet the requirements of communication service quality on UAV nodes with limited power and limited bandwidth, adapt to the rapid changes of network topology, and at the same time reduce the routing overhead of maintaining the network as much as possible. [0003] The Dynamic ...
