Internet of Things Notes

Here are some random notes by Tim Bird about the Internet of Things:

Issues

 * security
 * privacy
 * data storage scalability
 * bandwidth
 * power requirement - unwired sensors need small power requirements
 * cost - millions of units need low BOM (e.g, 10 cents)
 * system size (RAM should be internal to avoid separate DRAM price)
 * product lifespan (aka upgradability)

Stages of IOT deployment
(Based on Rose)

1) personification of dumb objects Objects become a proxy for a user (e.g. smartphone becomes your keys for wireless unlocking and garage-door opening)

2) Partially Autonomous Sensor Networks e.g. smart fridge knows expiration date, and sends alerts or auto-creates a grocery list

3) Autonomous Independent Devices e.g. smart fridge orders food autonomously

Existing IOT systems

 * Solar panels on Tim's house - reports and notifications on internet, read-only
 * has hub in home, with power-line networking from inverter to hub, then using home network from hub to internet
 * smart meters on Tim's house - reports on internet, read-only, not sure how data is transmitted to PG&E
