The deployment of wireless sensor network (WSN) forms a metric step to make the end of the desired system aim design. Deployment procedure can improve the information collected by giving more priority to the events which are more desired to be supervised; in addition, it can optimize the paths which link the network node among them as presented in this work. In this paper, we have improved the communication...
Wireless personal area networks (WPAN) are wireless sensor networks (WSN) designed for allowing a low-cost, low-power and short-range wireless communication. The IEEE 802.15.4 is the WPAN standard which satisfies these features and facilitates diverse self-configuring operation processes for adapting to different environments and applications. One of these processes is responsible for resolving the...
IEEE 802.15.4 is a wireless technology aimed at the transmission of information at low rates and short distances. Therefore, the expected traffic carried by these networks is one whose transmission rates are low, i.e. information captured by sensors. The extension of this technology to higher data rates is a challenge that gives us the opportunity to support additional services. This paper deals with...
In this work, we present UCare (Urban Care), a context-aware, flexible architecture that provides rich environment adaptation services to disabled users. We have considered bidirectional adaptability, that is, adapting the system interface to user capabilities and system capabilities to user needs. To accomplish this goal, UCare provides two operation modes: non-interactive, whose main property is...
