Embodiment

[0055] Embodiment: The whole process can be divided into network establishment and maintenance, service transmission, network establishment and maintenance mainly include the addition and deletion of neighbors, and the establishment and maintenance of routes. At this time, the AP is mainly working. This process is to form a suitable The wireless network for transmitting signals is prepared for business transmission. Service transmission is the process of voice or data service initiation, and the service is initiated by HT.

[0056] The specific implementation process of the protocol design of the present invention is described in detail below:

[0057] 1. Network layer

[0058] The main function of the network layer is to use the packet transmission method to transmit the information from the source to the destination according to the specified route. It is the most important layer in the ADHOC network. A large number of functions with AD HOC characteristics must be realized ...

Abstract

The invention aims to provide a wireless multi-hop ad hoc network communication method, which comprises the steps of network establishment and maintenance, and service transmission. The network establishment and maintenance comprises the following steps of: finding of neighbors; adding and deletion mechanisms of the neighbors; and establishment and maintenance of a route, in which the interaction of neighbor information among network nodes ensures that each network node finally possesses a topology table of whole network connection relationship, then a main operation node of the network nodes is used to calculate the route of the whole network according to the topology table and notifies other network nodes in the network of routing information in an information interaction mode at the same time, and the topology table and a routing list respectively saved by each network node are kept consistent to finish the establish of the network when the network is finally steady. The service transmission comprises the following steps of: search of an access point, link application, link establishment, service transmission and link demolition. A self-developed wireless multi-hop ad hoc relay network of the invention can finish the communication in tunnels or on occasions with similar characteristics.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a self-organizing network communication method based on wireless grouping protocol, multi-hop, centerless, and capable of independent networking. Background technique [0002] With the advancement of science and technology, people's requirements for information exchange are getting higher and higher, but the cellular mobile communication system must have the support of functional facilities such as base stations and mobile switching centers, and wireless local area networks generally work with access points (Access Point) and wired backbone network mode. But for some special application occasions, the centered mobile communication technology is not competent. For example, the rapid deployment and advancement of troops on the battlefield, the rescue of large-scale disasters such as earthquakes and floods, field expeditions, remote mine operations, and large-scale meetings or...
