Improvement of QoS in IMS network using network coding

Network coding provides a powerful and effective mechanism, instead of sending packets directly on the channel, the end node is allowed to combine and encode one or more packages before sending them. This process improves the speed of the performance, the rate of the transmission. In this paper, we present a survey of variants of network coding; we present the advantage of network coding in network convergence to IP Multimedia Subsystem (IMS), the classification of network codes, with their advantage. We show by analyzing the strategy of Network Coding, and the performance of the implementation of network coding in terms of messaging and media streaming in the generation IP Multimedia Subsystem network (IMS). We conclude that network coding can improve throughput, minimize transmission delay and minimize energy consumption in the networks of future generations IMS. Following the Network Coding can offer exciting possibilities for efficient transmission and helps raise the growing challenges of different types of applications on the Internet and media convergence based on IP IMS network.
