Network Coding

Network Coding Summary

• New form of coding breaking with the end2end paradigm

• Introduces the RECODING functionality

• Versatile code: works with different complexity levels

• Should be applied in• Multi hop networks

• Multi path networks

• Mesh Networks

• Easily deployable with SDN/NFV

5G COMPRESSED SENSING

Compressed Sensing

Several 5G applications are possible, we focus on meshed multi-

camera scenarios (e.g. augmented reality)

Objective: Combine CS and NC (analog and digital) in theory and

implementation to improve delay ↓, resilience ↑ and complexity ↓.

Agnostic combination CS/NC: Only individual gain per camera

(spatial correlation not exploited), reconstruction/decoding at the

sink resulting in high complexity

Proposed joint CS/NC design (analog and digital): Holistic in-

network processing based on compressed compute and forward

(CCF) with distributed partial decoding and clever protocol design

(active sensing).
