In the present embodiment, first set of terminal or second set of terminal comprise at least one terminal.Coding router goes for wireless or wired multiple network, by network code to data, and the Internet resources that take in the time of can significantly reducing the data network transmission, elevator system throughput.
As improvement to above embodiment, coding router also can not contain transmission control module, data reception module sends to coding module with first data, second data, and coding module carries out network code to first data and second data, and sends to data transmission blocks.
The embodiment flow process of network coding communication method of the present invention as shown in Figure 4, in the present embodiment, based on system shown in Figure 2.Terminal 1 is in cell base station 1 coverage, and terminal 2 is in cell base station 2 coverages, and cell base station 1, cell base station 2, broadcast base station interconnect by coding router, broadcast base station coverage cell base station 1, cell base station 2; Gateway is used for being connected with other backbone networks.In the present embodiment, terminal 1 sends data a (first eight bits is 01010011) and gives terminal 2, and terminal 2 sends data b (first eight bits 11001010) and gives terminal 1; Digital coding threshold value 60.This method may further comprise the steps:
The data that step 401, receiving terminal send, and send to coding router;
Cell base station 1 receives 1 and sends data a, and data a is sent to coding router, and cell base station 2 receiving terminals 2 send data b, and data b is sent to coding router.
Whether step 402, judgment data transmission quantity are lower than the digital coding threshold value, if then according to the destination path transmission of request of data, finish current flow process; Otherwise, enter step 403;
The volume of transmitted data that coding router judgment data a, data b send.Volume of transmitted data needs binding data size, network resource utilization, network congestion, packet loss, data delay situation etc. to consider, and determines concrete account form according to the needs of real application systems.
In the practical application, when volume of transmitted data is lower than certain value, when promptly being lower than the digital coding threshold value, adopt the efficient of network code and broadcast transmission data, compare to the efficient that the terminal of being asked sends data by routing mode with direct, differ not too obvious, therefore also can directly adopt existing mode to send data; When volume of transmitted data is higher than the digital coding threshold value, adopt the mode of network code and broadcast transmission data, greatly improving data transmission efficiency.
Here, suppose that the volume of transmitted data in the present embodiment is 100, be higher than digital coding threshold value 60, then enter step 403.
Broadcast base station carries out the shared Internet resources of own service, adopts the bandwidth that takies of broadcast base station to characterize.Broadcast base station carries out the outer remaining bandwidth of own service, can be used for carrying out the broadcasting of network code data.Coding router need judge whether the broadcast base station remaining bandwidth can satisfy the required bandwidth of exchanges data, because broadcast base station covers terminal 1, terminal 2, so the remaining bandwidth to broadcast base station is judged, satisfies the required bandwidth of exchanges data, just can carry out network code.Here, the required bandwidth of exchanges data is 1M, and broadcast base station remaining bandwidth 2M satisfies the condition of exchanges data, then data a, data b is carried out network code.
The network code mode that adopts in the present embodiment is the step-by-step XOR, promptly data is compared by turn, carries out the XOR computing, and the value difference of data a, the corresponding position of data b is assignment " 1 " then, identical then compose " 0 " of place value.With data a and data b first eight bits is example: 01010011 and 11001010 carry out obtaining 10011001 behind the step-by-step xor operation, and subsequent bit is operated equally, and this does not give unnecessary details.(a b) sends to broadcast base station with network code data F.
Step 404, broadcast base station directly send to all terminals with the network code data;
In the present embodiment, broadcast base station and terminal adopt wireless connections.Broadcast base station can directly (a b) sends to terminal 1 and terminal 2 with network code data F.
Terminal 1 receive network code data F (a, b) after, (a b) carries out an xor operation again and decodes with data a, obtains desired data with network code data F.Terminal 2 is carried out similar operations.
In broadcast/group broadcast communication synthesis network, the extremely many or few situation of volume of transmitted data is actually rare, so in step 402, more under the situation, can adopt the mode of network code and broadcast transmission to transmit swap data.In the present embodiment, the network code digital coding mode in the step 403 can determine as required, also can directly comprise the information of decoding process or decoding parametric in the coded data of networking, when terminal receives the network code data, can decode accordingly.Present embodiment has effectively utilized the bandwidth of broadcast base station, has reduced the routing pressure of coding router.
As improvement to above method, Rule of judgment in step 402, the step 403 can save, and directly the data that receive is carried out network code by coding router, and sends to broadcast base station, by broadcast base station data broadcasting is sent each terminal, so just accelerated transfer of data.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the above-mentioned fact, the method is to finish by the relevant hardware of program command, this program comprises corresponding steps when carrying out.Described program can be stored in the computer read/write memory medium, and described storage medium can be ROM/RAM, magnetic disc, CD etc.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
