Description

A kind of novel radio network system

Affiliated technical field:

The utility model relates to field of wireless, is a kind of novel radio network system, specifically a kind of novel radio Mesh (based on wireless mesh network) system.

Background technology:

Along with development of modern computer technology, network technology is extensively applied to people's various fields in life.In traditional wireless lan (wlan); Each client all visits network through a Radio Link that links to each other with access point, and the user must at first visit a fixing access point (AP) if intercom mutually; This network configuration is called as single-hop networks; When in a single day the individual node fault took place single-hop networks, network connected interruption immediately, and network connection quality is poor.Use the conventional wireless network system, have several drawbacks: (1) reliability is low, when switch breaks down, and whole network paralysis; (2) the Internet outlet is single, only single outlet; (3) load is unbalanced, and all flow exports out from single; (4) networking cost is high, needs wiring, and each access point (AP) need be connected to center switch with netting twine, needs high power access point (AP); (5) radiation is big, and transmitting power is unfavorable for health all greater than 100MW.

The utility model content:

The purpose of the utility model provides a kind of novel radio network system, specifically a kind of novel radio Mesh (based on wireless mesh network) system.

The technical solution of the utility model is: a kind of novel radio network system; It is characterized in that: be made up of ADSL terminal, wireless backbone, WAP and Wireless Mesh terminal equipment, wherein the Wireless Mesh terminal equipment can be the subscriber equipment that notebook computer, palmtop PC, mobile phone, PDA etc. are equipped with wlan card antenna.

The beneficial effect of the utility model is: (1) is in the novel radio network system; Any wireless device node can be simultaneously as access point and router; Each node in the network can send and receive signal; Each node can carry out direct communication with one or more peer node, and is congested if nearest access point causes owing to flow is excessive, and data can be routed to a less adjacent node of communication flows automatically again and transmit so.The rest may be inferred, and packet can also continue to be routed to nearest with it next node and transmit according to the situation of network, till arriving the final destination.(2) the novel radio network system has been removed the wiring demand between the node, but still has redundancy scheme that distributed network provides and routing function again, has practiced thrift cost greatly.(3) in the novel radio network system, if add new equipment, it is just passable only need to connect with the mains simply, and it can carry out self-configuration automatically, and confirms best multi-hop transmission path.(4) in the novel radio network system, when interpolation or mobile device, network can be found change in topology automatically; And automatic adjustment communication route; To obtain the most effectively transmission path, the novel radio network system is by comprising that one group of WAP that is net distribution constitutes, and access point all adopts point-to-point mode interconnected through wireless relay links; When the individual node fault; Through automatic routing technology, from network topological diagram, delete malfunctioning node automatically, can join network automatically after the malfunctioning node fault recovery.(5) in the novel radio network system; Because each short transmission range of jumping is short, transmission data desired power is also less, and the novel radio network system uses lower-wattage that transfer of data is arrived contiguous node usually; Wireless signal between the node disturbs less; The channel quality and the channel transport efficiency of network improve greatly, thereby realize higher network capacity, such as in highdensity urban network environment; The novel radio network system can reduce the phase mutual interference of the neighboring user of using wireless network, improves the utilization ratio of channel greatly.

Description of drawings:

Fig. 1 is the utility model embodiment theory diagram.

Among the figure: 1, ADSL terminal, 2, wireless backbone, 3, WAP, 4, the Wireless Mesh terminal equipment.

Embodiment:

With reference to Figure of description 1; A kind of novel radio network system of this specific embodiment comprises ADSL terminal 1, wireless backbone 2, WAP 3, Wireless Mesh terminal equipment 4, and the Wireless Mesh terminal equipment is connected to WAP through wireless network; Some WAPs are formed wireless backbone through wireless network transmissions; Be assigned to the various network outlet to client according to the corresponding strategies wireless backbone, be connected, finally realize the access to netwoks of the network terminal with the ADSL terminal.

The principle of the utility model:

The wireless backbone of novel radio network system adopts optimized link state routing protocol, and the Link State in the whole network of dynamic calculation is confirmed optimum network routed path; Each access point forms Radio Link with his contiguous access point, access point can with the own contiguous direct communication of access point, each access point is the link information of the whole network of calculating separately; And send to other access points on the network to the link information of oneself, be convenient to other access paths and calculate the entrance link mass parameter; Access point can be selected the reasonable path of link-quality route data packets, adopts the multiple exit routing mode, and access point can be selected the best outlet access internet of path performance; When certain access point fault wherein, other access points recomputate link table, revise routing table; And reach the purpose of network failure self-healing; After the malfunctioning node fault recovery, network recomputates, and joins new node in the Radio Network System.

Claims

1. novel radio network system; It is characterized in that: form by ADSL terminal, wireless backbone, WAP and Wireless Mesh terminal equipment; Wherein the Wireless Mesh terminal equipment can be the subscriber equipment that notebook computer, palmtop PC, mobile phone, PDA etc. are equipped with wlan card antenna; The Wireless Mesh terminal equipment is connected to WAP through wireless network, and some WAPs are formed wireless backbone through wireless network transmissions, is assigned to the various network outlet to client according to the corresponding strategies wireless backbone; Be connected with the ADSL terminal, finally realize the access to netwoks of the network terminal.
