Middleware for energy-harvesting wireless sensor networks

April 11, 2013 // By Jean-Pierre Joosting
With EnOcean Link, EnOcean has launched the first middleware for energy harvesting wireless technology. You can now integrate EnOcean technology easier and faster into a wide range of applications and systems, such as those in smart homes.

The software provides a universal interface for wireless communication and automatically interprets information from EnOcean telegrams. As a result, sensor data such as moisture or temperature is prepared so that different devices, servers and even cloud services can process it immediately.

EnOcean Link converts the payload of an EnOcean telegram directly into data values. In doing so, the middleware automatically takes into account all specifications of the EnOcean protocol stack and the EnOcean Equipment Profiles (EEPs) of the EnOcean Alliance as well as encryption mechanisms. This means EnOcean Link provides all wireless applications with a ready-made key to the energy harvesting wireless world. Since the software interprets all data, it also ensures the interoperability of equipment from different manufacturers.

The use of EnOcean Link saves OEMs valuable development resources, which significantly quickens the time-to-market for energy harvesting wireless applications. Instead of developing their own software for a particular application in order to interpret the communication protocol of the energy harvesting wireless technology, OEMs can use the finished middleware for this purpose immediately. The same applies to any application that integrates or further processes the energy harvesting wireless technology as well as to each EnOcean radio frequency.

Manufacturers can now focus all their attention on the application and their core activities. At the same time, EnOcean Link makes it easier to implement energy harvesting wireless networks, for smart home and M2M systems. EnOcean will update EnOcean Link continuously to users in the first yeara nd by contract thereafter.
In a smart home application, for example, a gateway can use EnOcean Link to immediately interpret the information from energy harvesting wireless sensors, including temperature, occupancy and light intensity, and forward this information to a central building control system. It does not matter if the system is networked with BACnet, KNX, Z-Wave, ZigBee, Bluetooth LE (low energy) or other automation protocols. For cloud services, working with GSM or WiFi, the data speed needed
