Embodiment Construction

[0066] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0067] The present invention proposes a new measurement system framework, and the application source of the concept "interventional measurement" involved in the present invention will be introduced below. The so-called "intervention" is relative to "non-intervention", and the existing network nodes are basically "non-intervention" measurement nodes.

[0068] The intrusive measurement node used in the self-organizing network of the present invention is a network node capable of routing and exchanging data for other nodes and having measurement capabilities. The intrusive measurement node can process and redirect the data of other nodes, It can respond to measurement requests initiated by other nodes, and assist in the collection of changing routing information or o...

Abstract

The invention relates to an interventional measurement node which is used for self-organized network and comprises an application level processing module, a UDP processing module and an IP processing module. The interventional measurement node is a network node which can route and exchange data for other nodes and has measurement capability. The measurement node can process and redirect the data of other nodes, can response to the measurement request initiated by other nodes and can help to collect the constantly changeable routes or other information in network to help people to understand the transient state and the normal state of network topology. When being the intermediate node of the network, the interventional measurement node can adopt three transmission modes for data message according to IP elective contents: direct forwarding, copy forwarding and process forwarding, thus causing the intermediate node to receive the message. The interventional measurement node uses the executive mechanism of the application level processing module to execute measurement tasks and acquire the support of the network/an operating system and collects network performance information of the intermediate node, then the network performance information is added to the message to be transmitted to a destination node, so the interventional measurement of the self-organized network is completed.

Description

technical field [0001] The invention relates to a network measurement method, specifically, to an intervening measurement node used in an ad hoc network and a measurement method thereof, belonging to the technical field of network interconnection communication. Background technique [0002] The self-organizing network originally only refers to the wireless self-organizing network (Ad hoc network). Organizational networks, including P2P file transfer networks with self-organizing characteristics. Moreover, battlefield network (battlefield network), vehicle network (VANET), sensor network (SensorNetwork), etc. all belong to wireless ad hoc networks. Wireless ad hoc networks have the following unique properties: [0003] Network independence: Compared with conventional communication networks, the biggest difference of self-organizing networks is that a communication network can be quickly built at any time and any place. Its establishment does not depend on the existing netw...
