Opportunistic wireless Network Coding based on small-time scale Traffic Prediction

Focusing on the weakness of the traditional network coding, such as latency and high packet loss rate, this paper presents an approach ONTP (Opportunistic Network Coding based on Traffic Prediction), which is based on ARMA (Autoregressive-Moving Average) algorithm. The algorithm is trying to predict the next packet´s arriving time, and then use it to determine whether waiting for network coding opportunity. Results show that the algorithm improves the throughput, and effectively reduces network latency, achieves a balance between coding efficiency and user experience.
