• Paper summary: select three out of the
reading list (invalid after in-class presentation)
CS590 (Peng) 11
12. How to Summarize a Paper?
• From four aspects
– 3 strong points: 3 most important things stated by
the paper
• Could be combination of motivations, observations,
interesting designs, or clever implementations (1) from
the author’s perspective at the time; (2) your
perspective with the benefit of hindsight
– 1 or more weakness: what is the single most
glaring deficiency?
• Design flaws, poorly designed experiments, narrow-
scoped main idea, weak applicability, …
CS590 (Peng) 12
13. More on Paper Summary
• 1+ key assumption/observation that led to the
research
– What were the key observations?
– Where did the observation/assumption come from?
• Personal experience, or work environment, …
• 1+ core risk/obstacle
– What are they to prevent the research from
successful?
– Were the authors aware of them? Are these obstacles
eventually overcome?
• Optional: what if you were the author
CS590 (Peng) 13
14. Course Project (1/3)
• Several topics to be distributed
– from the list or come up with your own
• Project scope (on mobile networking)
– Apps: emerging issues for 5G apps (e.g., scalability,
delay, energy, security etc)
• Understand the requirements in support of new apps
• Disclose and quantify the (unanticipated) issues
• Explore solution ideas
• Design, implement and evaluate the new solution
• Example: massive IoT support (pain for massive connectivity,
emerging security risks, issues still unresolved by recent
proposals)
• Example: realtime support for VR/AR/autonomous driving
(latency is the key)
CS590 (Peng) 14
15. Course Project (2/3)
– Technology (wireless advances, architecture,
radio/core, SDN/NFV, protocol)
• Build a (simplified) 5G prototype or simulator
• Re-architecture: NFV for 5G (redefine and split
functions), mobile edging computing
• Redesign protocols: simplified signaling protocols
• Augment intelligence at end devices (data-driven) via
MobileInsight
– Enable runtime network analytics at devices
– Enable network analytics at scale (crowdsourcing)
– Take additional actions at devices when needed
– Type: measurement, simulation/emulation,
design, implementation,
