Embodiment

[0053] Effect of the present invention can carry out concrete simulation example illustration:

[0054] Using OPNET modeler 14.5 as the simulation tool, the specific simulation parameters are as follows:

[0055] 1) The UAV ad hoc network deployment area is 5000m = 5000m, and the number of nodes is 30, which are randomly distributed in the deployment area. The motion model of each node is Random Waypoint, and the moving speed range of nodes is 1-10m / s.

[0056] 2) The number of communication connections is 5 unidirectional data streams, and the Expoential Bit Rate is used to simulate the generated data packets, and 1024bit messages are generated at an interval of 0.2s.

[0057] 3) Node initial energy E 0 Set to 60J, sending a single message consumes 0.0085J, receiving a single message consumes 0.0063J, and the speed factor SF th The threshold is set to 0.9, the energy factor threshold EF th Set to 0.9, the scale factor threshold WF th Set it to 0.33, and the simulation tim...

Abstract

The invention discloses a method for implementing a DSR routing protocol based on an unmanned aerial vehicle ad hoc network. The steps are as follows: 1) expanding the state information of all nodes; 2) expanding source node routing request options, and adding a measurement factor flag on the basis of the original request options 3) After the source node initializes the extended routing request group in step 2), it initiates a routing request; 4) The intermediate node receives the routing request broadcast in step 3), and the intermediate node according to its own state and reads the measurement factor flag of the request option The bit value determines whether to receive the routing request, and the intermediate node calculates its own measurement factor and inserts the measurement factor flag bit of the request option to rebroadcast the request; 5) The destination node receives the routing request, and returns a routing response to the source node of the request. The method reduces the transmission delay, reduces the overhead of network control messages, and improves the stability of service data reception.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for implementing a DSR routing protocol based on an unmanned aerial vehicle ad hoc network. Background technique [0002] UAV ad hoc network is a wireless local area network that can be flexibly deployed without relying on fixed infrastructure. It has the characteristics of no center, multi-hop, self-organization, and dynamic topology. Due to the movement of UAV nodes, the topology of the ad hoc network will change drastically, which will have a serious impact on the stability of the network. The drastic change of the UAV topology is the main reason for the degradation of network performance. Designing a simple and efficient routing protocol to balance the node traffic in the network, reduce network overhead and improve the stability of the transmission link is of great significance to the UAV Ad Hoc Network communication. [0003] The traditional dynamic...
