Introduction

  • The ubiquitous computing in the home area is distributed at various scales throughout our daily lives. Moreover, development of ubiquitous home services and their implementations have important commercial values as well. Therefore, various projects and researches have been carried out for the ubiquitous home network applications.
  • Following this trend, Hanback Electronics developed a new ubiquitous home network test-bed, named as Ubi-HomeNet, based on wireless smart sensors (HBE-ZigbeX).
  • HomeNet makes smart sensors can work as a collector perceived sensing information in home areas as well as a controller of consumer home devices. Some actuator type sensors are deployed near the consumer home devices and are connected with their electronic switch by using several relay module developed by us. This collaboration among smart sensors and home appliances has led to a new trend to take more active ubiquitous home networks beyond the traditional sensor networks. By using our testbed, user can easily learn and evaluate the ubiquitous home network areas. Its text book covers not only a theoretical education on NesC of TinyOS but also experiments related with controlling home appliances.
