Abstract
The invention discloses a method for providing networking for a wireless node out of a service area. The method comprises the following steps: (1) a child node out of the service area searches neighboring nodes, and inquires whether a networked father node exists or not by broadcasting; (2) the child node transmits a networking request to the father node, and sets an address of the father node as a self gateway address after permission is received, thereby realizing networking through a route way. By the invention, a wirelessly covered blind area can be reduced without increasing a base station or a network server so as to effectively improve the utilization rate of a network, and the method is a high cost-performance method for providing networking for the wireless node out of the service area.
Description
Technical field
The present invention relates to a kind of method by the radio node in the wireless network being arranged to father node, child node and the radio node that the method that father node is arranged to the child node gateway is embodied as out of reach being provided networking.Specifically, can be arranged to father node to those with the radio node that radio network gateways such as base station, server directly link to each other exactly; Can not directly directly link to each other or out of reach but radio node that can link to each other with near the radio node that has networked is arranged to child node with base station, server, child node is arranged to father node the gateway of oneself, mode by this route is come connectivity serving network, thereby is the radio node adding network of out of reach.
Background technology
Various wireless technologys all have the covering power of oneself, do not wait from several meters to tens kilometers, and the last limitation of this distance has been doomed coverage hole can occur in some place.Traditional mode is the quantity that as far as possible increases base station, gateway, though can utilize the overlapping of network's coverage area to reduce the blind area like this, high cost but becomes its stumbling-block preventing the development.
If the network node of each networking is reconfigured, making it becomes " the subnet pass " that other treat network access node, can reduce the blind area as much as possible under the situation that does not increase base station, gateway like this, has improved network utilization effectively.
Concrete method is: those unlimited nodes that networked are arranged to father node, those out of reach still can search the radio node of father node and be arranged to child node, child node is the gateway of the address setting of father node one-tenth oneself, and so node just can utilize father node to be connected to network.
Summary of the invention
The objective of the invention is to, a kind of method by the radio node in the wireless network being arranged to father node, child node and the radio node that the method that father node is arranged to the child node gateway is embodied as out of reach being provided networking is provided.
The present invention is by the following technical solutions:
(1), near the node the search of the child node of out of reach, whether have the father node that has networked by the broadcast mode inquiry;
(2), child node is to the father node request of send networking, and obtains allowing the back child node that the address setting of father node is become own gateway address, the mode by route realizes networking.
Further, in the step (1), whether near the node the search of the child node of out of reach exists the father node that has networked by the broadcast mode inquiry; Receive and preserve the father node address behind the response message and according to the strong and weak priority of disposing order of signal.
Further, in the step (2), child node comes to send the request of networking to father node according to the order of priority, obtains allowing the back child node that the address setting of father node is become own gateway address, and the mode by route realizes networking.
Further, in the step (2), treat that network access node at first can send the request of networking to the highest node of priority, if be rejected then send request till being allowed to network to the node of inferior priority again, become child node this moment to be networked, and the node that has networked is a father node.
Further, after obtaining allowing networking to respond, child node can be arranged to the gateway address of oneself address of father node in the step (2), and the data of uplink and downlink all can be gone out by the father node routing forwarding.
By the present invention, can under the situation that does not increase the base station and the webserver, reduce the blind area of wireless coverage, improved the utilance of network effectively, be the method that a kind of high performance-price ratio of networking is provided for the radio node of out of reach.

Embodiment
The present invention mainly is by the node in the wireless network is arranged to father node, child node, simultaneously child node is arranged to oneself gateway to father node, and the mode by the route method that adds network realizes that the radio node of those out of reach provides the method for networking at last.Specifically, radio node to be networked is the signal of search base station, gateway at first, if search is less than own out of reach promptly is described, this node is near other radio nodes of search then, just send handshake if search, comprised inquiry the other side information that whether networked in this handshake, the node that has networked receives that can return an answer signal after the handshake feeds back inquiry information, and this answer signal has comprised the address information of self.Treat at first can preserve those address informations of network access node after network access node is received feedback information, come priority of disposing order according to the power of received signal then, treat that network access node at first can send the request of networking to the highest node of priority, if be rejected then send request till being allowed to network to the node of inferior priority again, become child node this moment to be networked, and the node that has networked is a father node.After obtaining allowing networking to respond, child node can be arranged to the gateway address of oneself address of father node, and the data of uplink and downlink all can be gone out by the father node routing forwarding.Just finished the course of work of the child node of out of reach by near father node networking to this.
The present invention realizes that by the father node route method that the blind area node networks may further comprise the steps:
Step 1: near the node the search of the child node of out of reach, whether there is the father node that has networked by the broadcast mode inquiry, receive and preserve the father node address behind the response message and according to the strong and weak priority of disposing order of signal.
Step 2: child node comes to send the request of networking to father node according to the order of priority, obtains allowing the back child node that the address setting of father node is become own gateway address, and the mode by route realizes networking.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
Fig. 1 is the application scenarios figure that networking is provided for the radio node of out of reach, and Fig. 2 then is the flow chart of concrete work.Concrete job step was divided into for two steps, specifically described as follows:
The first step, whether near the node the search of the child node of out of reach exists the father node that has networked by the broadcast mode inquiry, receives to preserve the father node address behind the response message and according to the strong and weak priority of disposing order of signal.
In second step, child node comes to send the request of networking to father node according to the order of priority, obtains allowing the back child node that the address setting of father node is become own gateway address, and the mode by route realizes networking.
From realization mechanism and flow process, use the better simply method that child node, father node are set come radio node for out of reach provide the service of networking be a kind of do not increase cost, approach efficiently, cover not enough problem good solution be provided for effectively overcoming.
