Meanwhile, the coding overhead is lower by reducing the coding ratio, which reflects the better robustness of our approach in dynamic environments.
Coding Ratio. It is defined as the percentage of the transmitted blocks produced by encoding Operation over all the transmitted blocks that are sent by peers.
However, it uses random push scheduling without considering the link transmission delay and the frequent reencoding operations make the coding ratio too high (in Figure 9).
Coding Ratio. The encoding operation of network coding not only consumes the computing resources but also increases the packet transmission delay.
