In order to enable the object, technical solutions and advantages of the present invention become apparent, root is described in detail below with reference to accompanying drawings
According to example embodiments of the present invention.Obviously, described embodiment is only a part of the embodiments of the present invention, rather than this hair
Bright whole embodiments, it should be appreciated that the present invention is not limited by example embodiment described herein.Based on described in the present invention
The embodiment of the present invention, those skilled in the art's obtained all other embodiment in the case where not making the creative labor
It should all fall under the scope of the present invention.
IEEE 802.15.4 standard describes physical layer and the media access control association of low rate wireless personal area network
View is ZigBee, WirelessHART, MiWi, the basis of Thread specification.
IEEE 802.15.4 network, which refers to, to be used same wireless channel in a POS and is marked by IEEE 802.15.4
The set also known as LR-WPAN network for one group of equipment that standard is in communication with each other.In this network, communicated according to possessed by equipment
Ability can be divided into full-function device (Full Function Device, FFD) and reduced function device (Reduced
Function Device,RFD).It can be communicated between FFD equipment and between FFD equipment and RFD equipment.RFD equipment it
Between be unable to direct communication, can only be communicated with FFD equipment, or data are forwarded by a FFD equipment outward.This and RFD phase
Associated FFD equipment is known as the coordinator (coordinator) of the RFD.RFD equipment is mainly used for simply controlling application, such as
The switch of lamp, passive infrared sensor etc., the data volume of transmission is less, occupies to transfer resource and the communication resource few.
It is LR-WPAN network by the FFD equipment for PAN network coordinator (PAN coordinator) in IEEE 802.15.4 network
In master controller, i.e. the central node of network.Central node PAN coordinator is other than directly participating in applying, also
Complete the tasks such as member identities' management, link-state information management and packets forwarding.
Since radio communication channel is characterized in dynamic change, minor alteration, the object of node location or antenna direction
The variation of the ambient enviroments such as mobile is likely to cause the acute variation of communications link signals intensity and quality, thus wirelessly communicates
Coverage area be not determining.This resulted in the quantity of LR-WPAN equipment in network and between them relationship dynamic
Variation.
IEEE 802.15.4 network can be organized into Star Network according to the needs of application, can also be organized into point-to-point
Network.Fig. 1 is the schematic diagram of Star Network structure according to an embodiment of the present invention, as shown in Figure 1, owning in hub-and-spoke configuration
