Description
Technical field
The utility model is about wireless communication technology field, especially with regard to a kind of self-organizing object for intensively accessing
Networked terminals equipment.
Background technique
Mass communication equipment can reticulate structure automatically by antenna sets in network, and each node in network has certainly
Dynamic routing function, each node can only be communicated with adjacent node, be the intelligent network of a kind of self-organizing, Self management, no
Need backbone network that can construct flexible network.Mobile Ad hoc network is a kind of self-organizing without any central entity
Network, under the support of prior designed various agreements, by cooperating between node；In movement, nothing complicated and changeable
Voluntarily networking in thread environment makes up the definite transmission distance of wireless device, by means of a plurality of retransmission technique to expand network
Coverage area, for user provide it is various service, transmission various businesses cordless communication networks.It needs not rely on existing fixation
Communication network infrastructure, it will be able to the communication network system that tissue expansion uses rapidly, and each node can move in network
State, optionally, frequently enter and leave network.Have than the wireless access of traditional point-to-multipoint mode many incomparable
The advantages of.
Super-intensive networking (Ultra Dense Network, UDN) will meet 5G and the following mobile data flow demand
Technical way.Super-intensive networking can get higher by the wireless network infrastructure deployment of more " densification "
Channeling efficiency, to realize that the power system capacity of hundred times of magnitudes is promoted in local hot spot areas.With the increase of site density,
Switching is excessively frequent by the co-channel interference by multiple intensive adjacent areas, and when moving by user, and user experience sharply declines.Pre5G
UDN solution, the interference that can change multiple base stations is useful signal, and set of service is constantly updated with cell is mobile, always
So that user is in the state of center of housing estate, realizes cell virtual, reach the user experience of consistency.Interference management and inhibit,
Cell virtual technology and the adjustment of small district dynamic etc. are the important research directions of Pre-UDN stage super-intensive networking.
The use of traditional mobile communication terminal depends on wireless access network, is not having solid foundation facility (such as base station
Or router) support under conditions of not can be carried out communication.Ad hoc network supports dynamic configuration and dynamic flow control, all-network agreement
Also be all it is distributed, the tissue of system and control are not rely on certain important nodes, so they allow node
Failure leaves network or network is added.That is each mobile node can be according to their own needs in whole network
It is arbitrarily mobile, and regardless of the communication connection how safeguarded with other entities.Therefore have News Search, positioning and restore to connect
The ability of connecing is the basic demand to equipment, and many communication terminals for being currently used for fixed network are all not used to mobile ad-hoc network
In.
Bluetooth technology, which does not need network fixation means, yet can also complete the communication of equipment room, but the application of Bluetooth technology
Have many limitations: one, transmission range is short, and interior short-distance wireless communication is suitble to use；Two, it is carried out between bluetooth specification equipment
When communication must one be main equipment one for from equipment, a bluetooth main side equipment at most can simultaneously with 7 from end equipment into
Row communication, i.e., be at most only capable of handling 8 equipment simultaneously, constrain its application in catenet；It three, is that Bluetooth technology cannot
Realize multi-hop transmission transmission, equipment needs manpower to configure and safeguard network connection.Therefore self-organizing network is transmitted in wireless forwarding
It is better than Bluetooth technology with the performance of transmission range etc..
The existing equipment for having ad hoc networking function, such as sensor, car-mounted terminal, only single radio channel
Plate can only could support multi-hop transmission using TDD mode, can not holding equipment work at the same time several different from group
In knitmesh network, can not holding equipment simultaneously receive and send messages with multiple and different communication nodes.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
