The unequal protection of Network Coding with multi-generation mixing

Abstract

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 [10]. 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.
