* "OpenWSN":https://openwsn.atlassian.net/wiki/ - repository for open-source implementations of protocol stacks based on Internet of Things standards, using a variety of hardware and software platforms.

h3. Examples

* "Broadcast example code":https://github.com/sw17ch/udp_broadcast_example - broadcast is probably better than multicast for IoT discovery.

h2. OS

* "ARM mbed":http://mbed.org/

* "Contiki":http://www.contiki-os.org/

* "Spark":http://spark.github.io/

* "RIOT":https://openwsn.atlassian.net/wiki/ - alternative to Arduino with CoAP included

h2. Networking

* "WiFi AP + client":http://imti.co/post/145442415333/raspberry-pi-3-wifi-station-ap describes how to setup a wifi dongle as both an AP and a client, routing between the two.  We don't need to route from the sensors to the internet, however.

h2. APIs

* "Mozilla IoT":https://iot.mozilla.org/ - Mozilla's IoT software based on WoT; provides a sample implementation that might be useful to follow for IronMan, at least in the UI.

* "Qeo Tinq":https://github.com/brunodebus/tinq-core

* "Twitter":https://dev.twitter.com/rest/public

** "RESTful API Design w/NodeJS and Restify":https://code.tutsplus.com/tutorials/restful-api-design-with-nodejs-restify--cms-22637

** "CURL":https://alvinabad.wordpress.com/2009/03/01/send-twitter-message-from-unix/ - may not work exactly like this with new API

** "tweet.sh":https://github.com/piroor/tweet.sh

* SMS

** "SMS via Email gateways per carrier":http://www.linuxjournal.com/content/system-status-sms-text-messages

h2. Home Automation

h2. Arduino

* "Deep Sleep Mode":http://www.esp8266.com/wiki/doku.php?id=esp8266_power_usage#sleeping_the_esp8266

** "Door Alarm w/ deep sleep mode":https://github.com/chaeplin/esp8266_and_arduino/blob/master/_48-door-alarm-deepsleep/_48-door-alarm-deepsleep.ino - This allows using both a software timeout and an alarm interrupt to wake from deep sleep.  Design is similar to this "PIR-based implementation":https://github.com/esp8266/Arduino/issues/1488 ("diagram only":https://cloud.githubusercontent.com/assets/25507805/25678678/de4659a0-304a-11e7-90d4-a5c19241e7f6.png)

h2. Security

* "Securing Embedded Linux":https://www.linux.com/news/securing-embedded-linux

* AES

** This is a symmetric encryption technique which means there is only one shared secret.  Public/Private keys are not used with AES.

** "Symmetric AES using IVs (initial vectors)":https://forum.arduino.cc/index.php?topic=88890.msg1726730#msg1726730

** Arduino Libraries for AES

*** "AES for embedded":https://github.com/spaniakos/AES/ (Arduino or Raspberry Pi)

*** "ArduinoLibs":https://github.com/rweather/arduinolibs contains a "crypto library":https://rweather.github.io/arduinolibs/index.html.

h2. Software updates

Three parts to a software update: bootloader, kernel and rootfs/apps.

# This adds u-boot as 3rd stage bootloader to Pi. First stage (in hardware) doesn't change and 2nd stage (binary blobs) only change with new SD cards.

# u-boot is used to swap between kernels and partitions, test sanity of new images.

# kernel fallback capability is required

# rootfs/apps fallback capability is required

* "Building Murphy-compatible embedded Linux systems":https://www.kernel.org/doc/ols/2005/ols2005v1-pages-21-36.pdf

* "Implementing update system for embedded Linux":https://stackoverflow.com/questions/6937592/implementing-an-update-upgrade-system-for-embedded-linux-devices discussion on stackoverflow
