Connecting Things to the Web Using Programmable Low-Power WiFi Modules

The authors present first experiences of using programmable low-power WiFi modules for connecting things directly to the Web. Instead of relying on dedicated low-power radio technology and specialized protocols, they leverage the ubiquity of IEEE 802.11 access points and the interoperability of the HTTP protocol. Using a loosely coupled approach, they enable seamless association of sensors, actuators, and everyday objects with each other and with the Web. Their experimental results show that low-power WiFi modules can achieve long battery lifetime despite the fact that they are using HTTP over TCP/IP for communication.
