Fragment to after other column coding, and label is denoted as the second ordered series of numbers { bn }.Purpose is that two neighboring information fragment is allowed to generate pass
The information fragment of loss still can be restored back to by system if being lost one of information fragment by calculating.Encapsulation
When, three coded slices are selected from { bn } at random, point of the position " 3k+1 " is in addition randomly selected from prime information fragment { an }
Piece is incidentally upper to be used as redundancy.The position of selection 3k+1 is just can be also to meet three coded slices above, in addition in quantity
Position is separated by not far, can substantially reduce the probability of failure.Two neighboring information fragment { an }, can pass through the calculus of differences of inclusive OR
Afterwards, another set information fragment { bn }, fragment data i.e. information fragment in figure are obtained.With reference to Fig. 4, such as it is lost
A group information fragment in { bn } still can be restored all information fragments { an } by other two direction.Number in figure
According to fragment i.e. information fragment.
The point-to-points transmission of the present invention, corresponds to multiple terminals by a control platform.Using Aloha mode, if successfully
Words, are no longer replied.Only reception failure when, can just reply.Both cost has been saved, communication contention aware will not be caused.It is not required to
Real time communication is wanted, using Store and forword communication mode.Due to increasing the information of early warning ID in data packet head, pass through ratio
To the ID in early warning ID and storage, selection is abandoned or is collected.It has any different with common being transmitted, is not to receive and terminate
It instructs and completes transmission, but whether the number by calculating the fragment in storage is completed to judge to transmit.The present invention does not fear
Discrete type packet loss, only special continuous two and more than two packet drops just will affect the recovery of packet.In this way, losing
Packet causes the probability of communication failure to be greatly reduced.
