“…Reference [20] applies network coding to each Group Of Pictures (GOP) of the video stream. Unfortunately, due to congestions and node churning, a node may fail to get enough linear independent blocks to decode a GOP before the playback deadline.…”

“…Unfortunately, due to congestions and node churning, a node may fail to get enough linear independent blocks to decode a GOP before the playback deadline. For this reason, reference [20] proposes also a hybrid solution which combines network coding with Priority Encoding Transmission (PET) [21]: the sender divides a GOP into multiple layers and applies a different PET level of protection to each of them according to their importance. The only reception of the main layer is sufficient for the reproduction of the GOP at a minimum quality.…”

Peer-to-peer streaming is a well-known technology for the large-scale distribution of audio/video contents. Its widespread adoption derives from the possibility of having a good scalability without the need for the deployment of expensive infrastructures such as Content Delivery Networks (CDNs). We think real-time streaming of lessons could open new interesting opportunities in e-learning systems by encouraging interactivity between teachers and learners.Delay requirements are very strict in interactive e-learning scenarios, where playback lag between the event in the real world and the received audio/video should not exceed a few seconds. Only a very short delay would allow students to ask questions during the lesson. At the same time, playback continuity is a key aspect too, since holes in the stream reproduction could seriously compromise the understanding of lectures. In this paper we compared some solutions that try to overcome the limitations of traditional mesh-based P2P systems, which are usually affected by long and unpredictable delays. We finally tried to outline which of the analyzed solutions appears the most suitable one to meet e-learning requirements.

In this contribution, we propose a novel Network Coding based LTE Cooperative-communication (NCLC) system. More specifically, our novel NCLC system is devised by incorporating a beneficial network coding scheme into the TD-LTE system. The benefit obtained by employing the network coding scheme in our NCLC systems are highlighted and analysed by both insightful formulae and illustrative examples. Particularly, Monte Carlo simulation based results suggest that our NCLC system outperforms the conventional TD-LTE by at least 3dB at an FER of 10 −5 .
