Distributed network architecture without fixed infrastructure support and position management method thereof

Abstract

The invention relates to a distributed network architecture without fixed infrastructure support and a position management method thereof. The distributed network architecture comprises a core networklayer, an access network layer and a sub-network layer, the position management method comprises the steps of position information reporting, adjacent subnet information pushing and anchor node pushing. Simulation experiments show that the signaling and data overhead of the scheme applied to the architecture is smaller than the signaling and data overhead of the existing mobile IP scheme appliedto the architecture. According to the invention, a service scene requiring network flexibility can be efficiently supported; the network has a rapid deployment capability and an anti-destroy capability; according to the location management method and system for the distributed network architecture, for the location management scheme of the distributed network architecture without fixed infrastructure support, the location management scheme of the architecture is verified through simulation, and compared with a traditional location management scheme, the data and signaling overhead is reduced.

Description

Technical field [0001] The invention relates to a wireless communication technology, in particular to a distributed network architecture without a fixed infrastructure and a location management method. Background technique [0002] With the development of wireless communication network technology, people have higher and higher requirements for the mobility of network devices. Most of the current mobile networks are built on the structure of fixed infrastructure. Fixed infrastructure can provide users with a high-security, high-quality communication network environment, but it also limits the flexibility of the communication network. In some special occasions, such as medical treatment, disaster relief, and military environments, communication networks with fixed infrastructure will no longer be applicable. [0003] At present, mobility management technology has attracted the attention of many international standardization organizations and research institutions. These organizatio...

Problems solved by technology

[0006] One of the purposes of the present invention is to provide a distributed network architecture without fixed infrastructure support to solve the problem of system paralysis caused by single-point failure of the centralized anchor point existing in the existing centralized network architecture based on the core network

[0007] The second purpose of the present invention is to provide a location management method based on no infrastructure support to solve the problem that the existing location management process only updates the user's location information for the current node and adjacent nodes, but cannot update the user location information for other nodes
