An European research, ESNA project ('European sensor network architecture'), has made communication lines easier for people. The system is based on cheap wireless sensors in various business applications including energy-efficient environmental controls.

The ESNA project have developed a flexible framework for business-oriented wireless-sensor network applications. Besides, ESNA is part of the EUREKA ITEA (Information Technology for European Advancement) software cluster; EUREKA is the European platform for research and development (R&D).

With regard to the system, it is a standard architecture to facilitate smart device communications, from environmental controls at home and domestic appliances to sophisticated control equipment in manufacturing facilities. The devices can be fitted into almost any device because their size is so small. Another plus is that they can be fitted at lower cost. Moreover, the devices are multifunctional: nodes can be equipped with various sensor capabilities including humidity, temperature, radiation, movement, gases and light. If one node fails, the network automatically 'rearranges' itself to ensure it runs smoothly.

With the Internet finding a niche in both our homes and at work, control and interactivity is intensified through the so-called 'Internet of things', from factory production to modern agriculture. The Internet of things got a huge boost from the development of wireless networks facilitating the interconnection of all types of sensors using radio communications.
