Support of the present invention concurrently accesses in the 6LoWPAN home gateway of service, and CPU module 1 adopts the cpu chip of the ARM framework that Samsung Electronics of Korea S produces, and concrete model is S3C2440.Memory module 3 includes SDRAM data storage and FLASH program storage.Human-computer interaction module 2 adopts 3.5 cun of LCD displays, display content mainly to include the database purchase inquiry interactive interface of the status display interface in visual gateway network configuration interface, gateway data repeating process, home wiring control interface and sensing data.6LoWPAN communication module 5a adopts the CC2530 module of low-power consumption 8051 microcontroller core.Bluetooth module adopts the GC-02 bluetooth module that Nanjing Guo Chun Electric Appliance Equipment Co., Ltd produces.Wi-Fi module adopts the WM-G-MR-09 module of USI company design.Ethernet communication module 5d adopts DM9000AEP network service chip.
As in figure 2 it is shown, support of the present invention concurrently access the 6LoWPAN home gateway of service realize method, comprise the following steps:
Receive the packet inputted from heterogeneous networks communication interface, and each packet is carried out business classification.
According to the data packet traffic urgency level at home network and real-time, each type of service carried out service priority M judgement, according to home system actual data transfer needs, set the value priority N to packet by the value of dynamic random variable C (t) and be estimated determining.
Packet priority Ft (P) is determined according to service priority M and value priority N, the computing formula of packet priority Ft (P) is: Ft (P)=P × N+Q × M, wherein, the value significance level of packet is represented with P, Q represents type of service significance level, P > Q > 0, and P+Q=1.
Packet is stored in high, medium and low three priority queries according to the height of packet priority respectively, wait in line scheduling, packing according to self-defining application layer unified management agreement according to the corresponding command, the function that sends then calling corresponding sub-line journey carries out the forwarding of data.
Each packet is divided into three big classes of business by the present invention, respectively security alarm data, terminal control director data and sensing data, again big for each business class is divided into three groups, respectively urgency traffics, real time business and non-real-time service according to urgency level and real-time.It is highest by the value priority level initializing of security alarm data, is medium priority by the value priority level initializing of terminal control director data, is low priority by the value priority level initializing of sensing data, and gives concrete numerical value.The service priority of urgency traffic is set as high priority, and the service priority of real time business is set as medium priority, and the service priority of non-real-time service is set as low priority, and gives concrete numerical value.
The enforcement of the method that realizes that support of the present invention concurrently accesses the 6LoWPAN home gateway of service specifically comprises the following steps that
Step one: after first 6LoWPAN home gateway has created main thread when system start-up, and carry out interface initialization, then start create and run bluetooth sub-line journey, 6LoWPAN sub-line journey, socket sub-line journey, after each sub-line journey receives data, will by application layer Unified Device management agreement UDCP, packet is divided into three major types, respectively security alarm data A1, terminal control director data A2And sensing data A3, and send signal to main thread.
Step 2: main thread has corresponding groove function to respond with it for these three sub-line journey, main thread reads the service priority M of the data of sub-line journey and data by groove function, and falls into a trap the value priority N of evidence of counting at groove function.
Wherein { 0,0.5,1}, as M=0, correspondence service priority is high priority to M ∈, is expressed as urgency traffic；As M=0.5, correspondence service priority is medium priority, is expressed as real time business；As M=1, correspondence service priority is low priority, is expressed as non-real-time service.
Wherein N ∈ { 0,0.5,1}, N=C (t) is in order to represent that the priority of certain data traffic types is selected by user in t, C represents user, C (t) value is more little, and the priority that N represents is more high, and the value of C (t) is determined according to the judgement of present case by processor.System default is by information A1It is highest for being worth priority level initializing, i.e. NA1=0, information A2Value priority level initializing is medium priority, i.e. NA2=0.5, information A3Data value priority level initializing is low priority, i.e. NA3=1, certainly, the acquiescence value of N can be modified according to the demand of user.
Step 3: calculated packet priority Ft (P) by the service priority M of data and value priority N.Represent the value significance level type of service significance level of packet respectively with P and Q, the value significance level of packet has countless multiple value more than the type of service of packet, therefore P > Q > 0, and P+Q=1, P and Q.Packet priority Ft (P) computing formula is: the value of Ft (P)=P × N+Q × M, Ft (P) is more little, represents that priority is more high.
Step 4: packet is stored in high, medium and low three priority queries according to the height of packet priority respectively, wait in line scheduling, packing according to self-defining application layer unified management agreement according to the corresponding command, the function that sends then calling corresponding sub-line journey carries out the forwarding of data.
Finally, it is noted that above are only presently preferred embodiments of the present invention, any those familiar with the art is in the technical scope that the invention discloses, the change that can readily occur in or replacement, all without departing from claims of the present invention limited range.
