Problems solved by technology

[0010] In the prior art, for frequent network topology changes, it is difficult for traditional fixed network routing protocols to reflect the network topology in a timely and accurate manner. Especially in a network with frequent link changes, a large amount of update information will inevitably occupy a considerable amount of bandwidth and increase protocol overhead

Embodiment 1

[0041] Embodiment 1: The process of establishing a route is the process of continuously providing the transmission direction to the destination for information.

[0042] as attached figure 1 Shown:

[0043] a) In the ad hoc network, the source node S transmits information to the destination node D.

[0044] b) There may be many links or paths between the source node S and the destination node D, such as path 1, path 2, and path 3.

[0045] c) The source node S does not need to find the shortest path to the destination node D, such as path 1.

[0046] d) The source node S can establish a path to the destination, so that information can be continuously transmitted to the destination.

[0047] e) The route may change continuously depending on the position of the node relative to the destination, but always towards a specific destination, eg destination node D.

[0048] f) In an ad hoc network, when the information to be transmitted to the destination node D is at a relatively...

Abstract

The invention discloses a wireless ad hoc network routing protocol propagation range dynamic control method, which comprises the following steps of: preferentially selecting and dividing a propagationrange according to the purpose of a propagation path in an ad hoc network, and dynamically adjusting a transmission range by controlling network flow and transmission rate information in the ad hoc network so as to adapt to network topology change in time and improve radio resource utilization efficiency. The system performance is stable, network wiring and operation control management are convenient and efficient, the service quality is guaranteed, the network time delay is reduced, the diversity and reliability of transmission paths are enhanced, and the network resource utilization rate isimproved.

Description

technical field [0001] The invention relates to IPC classification H04W40 / 02 communication routing or path selection technology or H04W28 / 00 wireless communication network traffic or resource management technology, especially a method for dynamically controlling the propagation range of wireless ad hoc network routing protocols. Background technique [0002] Ad hoc network is a network that combines mobile communication and computer network. The information exchange of the network adopts the packet switching mechanism in the computer network. The user terminal is a portable terminal that can be moved. Each user terminal in the ad hoc network has a router. And host two functions. As a host, the terminal needs to run various user-oriented applications, such as editors, browsers, etc.; as a router, the terminal needs to run the corresponding routing protocol, and complete the data packet forwarding and routing maintenance work according to the routing policy and routing table, ...
