Abstract: “We present a simple sequential data protocol (SSDP) - an implementation of a lightweight message encoding and exchange protocol for Arduino-based sensor devices. The protocol supports simple data types, strings and binary arrays with low overhead. It defines several types of messages used to discover device metadata, send and receive sensor reading values and runtime parameter values, as well as alarms. The SSDP Arduino library is simple and has a low memory footprint. In conjunction with mesh networking, SSDP can be used to quickly and efficiently build sensor networks based on inexpensive Arduino hardware.”
