Network-enabling embedded devices require a different design approach than building traditional enterprise data networks. Devices in industrial and home control applications simply cannot bear the cost of a 10/100 Ethernet connection and full TCP/IP stack when you consider that thousands of devices might be involved. Lighter protocols, such as LonTalk used in LonWorks networks, provide a less complex mechanism for transferring data while supporting key network functions such as remote management. However, for simple nodes such as sensors or lights which may transfer only bytes of data once every 15 minutes, even a light protocol is too heavy.
