Abstract

The invention discloses a DSR routing protocol implementation method based on an unmanned aerial vehicle ad hoc network. The method comprises the following steps: 1) state information of all nodes isexpanded; 2) a source node routing request option is extended, and a measurement factor flag bit is added on the basis of the original request option; 3) a routing request is initiated after the source node initializes the routing request packet expanded in the step 2); 4) an intermediate node receives the routing request broadcasted in the step 3), decides whether to receive the routing request or not according to the state of the intermediate node and the numerical value of the measurement factor flag bit of the read request option, calculates the measurement factor of the intermediate node,inserts the measurement factor flag bit of the request option and rebroadcasts the request; and 5) a destination node receives the routing request and replies a routing response to the requested source node. The method reduces the transmission delay, reduces the cost of the network control message, 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.
