Problems solved by technology

The problem with this solution is that access to application streams is based on the principle of first-come-first-served, and does not take into account the different levels of user requirements for application streams, and filter the priority of application streams
However, the existing schemes use a fix

Embodiment Construction

[0031] The main functional modules involved in the method of the present invention, the description of the service quality of the application flow, the control mode and negotiation algorithm of the QoS negotiation mechanism, and the transmission control of the application flow are analyzed in detail below, and finally the application scenario of the present invention is introduced.

[0032] 1. Main functional modules

[0033] As shown in Figure 1, the research content involved in the present invention is the gray part in Figure 1, and the functional modules include QoS mapping, QoS negotiation, QoS resources, routing table calculation, and transmission control. QoS mapping expresses user QoS as a description form that can be processed by a computer; the QoS negotiation module runs the QoS negotiation mechanism, and the QoS negotiation mechanism establishes negotiation rules based on the effective resources of the network and the different QoS requirements of the application flo...

Abstract

The present invention discloses a movable wireless route method of self organized network which can ensure the service quality. The present invention aims at the wireless movable QoS route agreement of the self organized network, which induces the applying Qos agree system into the strategic decision as the network bandwidth resource is limited with an unsteady link. The present invention comprises the following steps: (1) expressing the different QoS requirement of the customer such as each QoS index and arrange, the priority of the flow, the network resource require and the lose profit value of the customer to the expressed form which can be handled by the computer; (2) acquiring service quality parameter of the network resource and link through the QoS resource mould; (3) carrying out the agree system according to the QoS require and the valid resource of the network;(4) calculating and finding a special applying QoS route according to the QoS index of the QoS agree system; (5) transmitting an applying flow transmission reflect sheet of controlling mould to control the sending of the applying flow. The present invention can find the route according to the movable index, can maintain and agree the voice video and other applying flow QoS. The present invention can get a large customer profit; and the present invention can ensure the soft transmission quality of the applying flow of the network.

Description

technical field [0001] The invention relates to a routing method for a wireless mobile ad hoc network that dynamically guarantees service quality, and belongs to the technical field of quality of service routing (QoS Routing) in a wireless mobile ad hoc network (also known as MANET, Mobile Ad hoc Network). Background technique [0002] Mobile wireless ad hoc network is a dynamic, multi-hop, wireless network composed of a group of mobile hosts. Mobile nodes in the network establish connections through wireless, multi-hop communication links. Unlike traditional wireless networks, mobile wireless ad hoc networks have no fixed network infrastructure or management support. When the mobile node joins or exits the network, the topology of the network changes dynamically; and the bandwidth of the wireless channel is limited and the wireless link is unstable. [0003] The applications of mobile wireless ad hoc networks include military affairs, emergency disaster relief and so on. ...
