Embodiment two:
As shown in Figure 2, the present embodiment provides a kind of WIFI communication means, and described method comprises:
Step S210: according to default routing algorithm from WIFI routing table, selects one by the direct-connected transmission link formed of source device, one or more intermediate equipment and target device successively WIFI; Described source device is WIFI communication equipment initiating equipment, and described target device is WIFI communication answering equipment.
Step S220 adopts described transmission link, carries out WIFI communication.The routing table of described WIFI routing table for being formed in the routing table described in embodiment one or described embodiment two.
In the present embodiment WIFI communication means, according to the transmission path that WIFI routing table is selected, by the direct-connected splicing link of the direct-connected WIFI formed of source device, at least one intermediate equipment and target device successively WIFI, carry out WIFI communication by described transmission path, have employed intermediate equipment and carry out relay forwarding.Adopt WIFI communication means described in the present embodiment, the long distance WIFI that can realize between source device with target device communicates, reduce simultaneously source device and target device can not WIFI direct-connected time, the probability of the failure that WIFI communicates.
Concrete as when between equipment a and equipment c because reasons such as apart from each other or connection failures, can not WIFI be set up direct-connected.By inquiry WIFI routing table, it is direct-connected that discovering device b both establishes WIFI with equipment a, establishes WIFI again direct-connected with equipment c simultaneously, then can select by equipment a to equipment b, again by equipment b to equipment c two sections of WIFI direct connected links, the transmission link be in turn connected into, carries out WIFI communication.
As shown in Figure 3, as the further improvement of the present embodiment, before carrying out described step S210, also step S200 is comprised.Described step S200 is direct-connected for determining can not to set up WIFI between described source device and described target device.Can set up between described source device and target device WIFI direct-connected time, then can communicate by WIFI is direct-connected, the resource shared by communicating with as far as possible few minimizing WIFI.
Carry out that WIFI between described source device and target device is direct-connected to be comprised:
Whether the direct-connected number of WIFI that source device is set up reaches the connection upper limit;
If not, the WIFI directly set up between described source device and target device is direct-connected;
If so, then cancel policy selection cancel the WIFI direct connected link of a described source device according to connecting, and to set up WIFI direct-connected with described target device.
Strategy is cancelled in described connection, can be the minimum WIFI direct connected link of WIFI direct connected link that in the fixed time, communication frequency is minimum or route messages.
As the suboptimization again of this enforcement, as shown in Figure 4, method described in the present embodiment, additionally provides and specifically how to realize determining to set up the direct-connected step of WIFI between source device and target device, specifically comprise:
Step S201: judge between described source device and described target device, whether built vertical WIFI is direct-connected; If not, then step S202 is entered; If so, then having established between source device and target device that WIFI is direct-connected can direct communication.Determination methods can be the WIFI routing table by searching source device, specifically can be: the MAC Address of target device is mated with the MAC Address in the WIFI routing table in source device, if the match is successful, and source device is 1 to the jumping figure that turns of target device, then set up WIFI between source device and target device direct-connected; Wherein, the jumping figure correspondence hop count of WIFI direct connected link is turned.
Step S202: judge whether described target device is that described source device can search non-connection device;
If not, then step S203 is entered;
If so, then WIFI can not be set up between described source device and described target device direct-connected.The MAC Address of the MAC Address of target device with the equipment that can search can be mated by concrete realization, the equipment that the match is successful then for searching.
Step S203: the WIFI set up between described source device and described target device is direct-connected; If set up unsuccessfully, then WIFI can not be set up between described source device and described target device direct-connected.
The method for building up that concrete WIFI is direct-connected, can adopt any one method of the prior art.
The determination whether can setting up WIFI direct connected link between source device and target device simply can be realized by said method.
In addition, many transmission paths may be provided in described WIFI routing table, need according to route selection algorithm, select the transmission path that meets demand.
Route selection algorithm has multiple, provides two kinds of route selection algorithms in the present embodiment.
The first: the routing algorithm that intermediate equipment is minimum, namely select the minimum transmission path of intermediate equipment number of process.This route selection algorithm selects the Route Selection of the minimal communication resource that takies.
The second: intermediate equipment number is less than the routing algorithm of threshold value, described threshold value is the numerical value prestored.Adopt this routing algorithm, a transmission paths can be selected more fast, to reduce the time delay of WIFI communication.
In concrete implementation procedure, determine that the method for the WIFI direct connected link hop count of transmission path process has multiple, a kind of transmission path intermediate equipment number of tag-detection is provided in the present embodiment.What WIFI direct connected link hop count equaled intermediate equipment number adds 1.Tag-detection is that source device sends an explore frame, is assigned with certain number of tags, and when after arrival equipment, then number of tags subtracts 1 automatically, when number of tags reduces to 0, then stops forwarding explore frame, and described detecting label is entrained by described explore frame.
When adopting the routing algorithm that described in the first, intermediate equipment is minimum, after reaching target device in more each transmission paths, the remainder of detecting label; Remainder is larger, then the intermediate equipment of transmission path process is fewer, and transmission path is shorter.Selecting the maximum transmission path of label volume residual is transmission path.
When the routing algorithm adopting the intermediate equipment number described in the second to be less than threshold value, source device sends tag-detection frame, and the intermediate equipment number that a transmission paths reaches target device if find that there is is less than threshold value, then this path can be selected as transmission path.Adopt in this way, without the need to more each transmission paths the intermediate equipment number of process, also without the need to waiting for that each transmission paths completes detection, thus be conducive to the quick selection of transmission path, and the face of selection is relatively wider, when wherein a transmission paths breaks down, other transmission path can be selected to carry out WIFI communication, and always according to route selection algorithm, can not determine that same cannot carry out the transmission path of normal WIFI communication.
