Abstract :
Apply chaos in the digital fountain codes, which is in the transport and application layer of communication network. An encoding and decoding algorithm of LT codes based on Kent chaotic map is proposed. In the encoding process, we use the randomness and ergodic properties of chaotic sequence to determine degree value and neighbors of each encoding packet. The performance of LT codes based on chaos is compared with that of LT codes implemented with standard pseudorandom number generator in C programming language. It is found that LT codes based on chaos have better performance.
