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).
