Introduction to the Special Issue on Software Technologies for Embedded & Ubiquitous Systems

Ubiquitous embedded systems are one of the technology drivers to improve our daily life, much more than we normally recognize. To engineer such systems we have to overcome many challenges. For example, such systems typically have to support low-power network connection with nearby computing devices in the context of high mobility, while at the same time incorporating the latest hardware developments in order to allow for cost-effective yet powerful systems. The following five articles in this special issue cover two important issues of software technologies for embedded and ubiquitous systems: safety critical systems and wireless networking technologies and applications
