s-net®

Technology for Extremely Power-Efficient Wireless Sensor Networks

Wireless Sensor Networks

With the need for security, mobility and flexibility ever increasing, wireless sensor networks are used in virtually all areas of everyday life. Characterized by distributed data acquisition, decentralized application software and mesh communication, they enable innovative solutions. The Fraunhofer Institute for Integrated Circuits IIS has undertaken research and application development in this area for many years. Our work ranges from technology for simple point-to-point data transmission to small, centrally controlled networks to large-scale self-organizing communication networks. Where standard wireless solutions fail to meet requirements (e.g. in terms of data rate, power consumption, communication range, latency, network topology or miniaturization), we develop custom systems.

Fraunhofer IIS’s services in the area of wireless sensor networks range from the selection of suitable protocols to the development of custom solutions and applications. Thanks to our many years of experience with various frequency bands (402 MHz, 434 MHz, 868 / 915 MHz, 1.9 GHz, 2.4 GHz and 5.8 GHz), we are able to offer wireless solutions tailored to your specific requirements. Having partial solutions ready, Fraunhofer IIS also provides rapid prototyping services.

Wireless sensor nodes can be added to many technologies for industrial or domestic use in order to increase their convenience and efficiency.

Fraunhofer IIS’s s-net® technology is geared towards these three main application areas:
– Durable systems of distributed data acquisition
– Tracking of people and objects
– Systems that autonomously perform tasks

Over the past few years, a large number of measurement, monitoring and control applications involving wireless sensor networks have been implemented based on the s-net® technology. Offering adjustable protocol parameters and extremely low power consumption for long service life, s-net® provides an excellent basis for client-specific solutions. Another reason why sensor network solutions based on s-net® are so successful is its dynamic, self-organizing network topology, which translates into easy configuration, low maintenance needs and high robustness.
