Efficient Network Coding packet selection model for QoS-based applications

In this paper, we study Network Coding (NC) at switching level. We use a novel NC algorithm to select, among received packets, those to be coded and released into the network. The selection is based on address correlation and QoS is attained based on delay optimization. The main feature of our algorithm is that it enhances the coding decision and guarantees decodability of transmitted packets. We developed a testing model to evaluate the performance of our proposed algorithm. Significant throughput and QoS improvements can be observed when our algorithm is compared with traditional NC schemes.
