Edge computing
• One-hub distance devices
– Avoiding latency overhead
• Edge is preferable… but
– Limited
• Hard to scale
– Microservices?

Mobile analytics
• Mobile context
– (Device, communication link, back-end)
• Back-end = other devices
– Opportunistic evaluation
• Sensing
• Processing
• Networking
• Storage
• Etc…

Take aways
• Context evaluation for opportunistic adaptation of applications improves performance and energy of devices.
• Edge infrastructure is preferable, but limited.
• Opportunistic fog computing depends on exploitation of devices ‘context.
