Cuckoo - offloading

• Computation Offloading

• Select between Local or Cloud Execution of Workloads

• Communication Offloading

• Push Notification for Anything

vrije Universiteit

Computation Offloading Framework

• Runs on Android, integrates with Eclipse

• Multiple implementations of compute intensive parts

• Remote and local implementation bundled together

• Deals with network connectivity issues (Ibis SmartSockets)

eyeDentify: object recognition

• Compute intensive operation

• Local implementation is inaccurate

• Remote implementation runs in parallel and uses better accuracy parameters

• Results

• Up to 40 times less energy

• Up to 60 times faster

• better recognition quality

vrije Universiteit

Communication Intensive Apps

• Applications and widgets that

• communicate periodically

• RSS Readers, Weather, Traffic,Social Networks, Sports Scores,News, Stock Market, etc.

• built by 3rd party developers

• Do Pull-based Web Requests

• Information Monitoring Applications

vrije Universiteit

Communication offloading

• No Update Delays• No Energy Waste• No Server Modifications• Works for 3rd party devs
