Multicast route method of mobile self-organizing network system

Abstract

The present invention discloses a multicast route method of a mobile self-organizing network system. The method of the present invention is put forward against the prior art that the present multicast route method can not satisfy the self-organizing network with rapidly moving nodes, and the method comprises the steps as follows: a node regularly sends a HELLO message to perform detection and update of a neighbor node; a source node performs a route orientation prediction by using geological position of the node; the source node obtains positional information of a multicast group object node,then adds object node ID and the positional information into a data head object node domain, and sends a DATA message; and other nodes determine how to forward the data according to the head information. The present invention puts forward a data transmission guiding mechanism based on positional information prediction, and applies a delay tolerance technology to the network, therefore in an environment where the nodes move rapidly and topology changes quickly, the method of the present invention can raise use efficiency and data delivery rate of network data transmission with the preconditionthat the requirement of low time delay for the network is satisfied.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a routing method for a mobile self-organizing network system. Background technique [0002] For traditional wireless ad hoc networks, nodes are usually in a static or low-speed motion state. In this case, the network topology changes slowly, and the requirements for route selection, node communication bandwidth and transmission delay are low. However, in a mobile self-organizing mobile network system such as UAV, the UAV network nodes will move and fly at high speed, and the mobile self-organizing network composed of UAV groups is located in harsh environments such as battlefields, and the entire network operates normally and stably. The situation is worse. In this case, indicators such as network data transmission energy consumption are no longer the main aspects that constrain the design of the entire network routing algorithm. In the UAV mobile self...
