Abstract:
1. A method for frame aggregation transmission of wireless network system, comprising: receiving an statistical packet error rate based on channel quality, transmission opportunities N, linearly independent probability that the receiver will receive k mixed packets, and an indicator value of not correctly received packets; calculating a network coding length k based on the statistical packet error rate, the transmission opportunities N and the indicator value; using Mixed Generation Coding (MGC) to generate k mixed native packets and N−k mixed coded packets from a plurality of retransmitted packets and a plurality of new packets, wherein the MGC is given as an equation of: where p 1 , p 2 , . . . , p k* and p 1 , p 2 . . . , p k* are corresponding native packets of the previous and current generations, the parameters c i,j , c i,j , and c i,j are a random coefficients, wherein the k* MGC is given as equation: where the r is additional packets, the Pr PER is given as equation: where the L m =h+l+32 bits, h is a number of bits allocated for a control overhead and l is a number of payload bits for the linear combination of all k native packets, wherein bit error at the receiver is assumed to follow a Bernoulli trial with probability Pr BER ; creating a frame aggregation of mixed coded packets for transmission through a MAC layer; and receiving the frame aggregation and decoding the mixed coded packets.
