The unequal protection of Network Coding with multi-generation mixing

In this paper, we study and analyze the unequal protection characteristic of Network Coding (NC) with Multi-generation Mixing (MGM). MGM supports unequal protection by providing different levels of reliable communication for different groups of sender packets. MGM is a generalized framework for practical network coding that enhances its performance by improving the reliability of delivering sender packets. By employing MGM, generations are created from sender packets. At the same time a mixing set consists of a fixed number of generations. In this paper we analyze the capability of MGM to support unequal protection of MGM mixing set generations.
