Abstract-This paper presents an open source implementation for a data-link layer protocol specified in IEC 60870, protocol specification for telecontrol networks. It has been tested over LEON an embedded system with a Linux based operating system. Protocol engineering methods have been used in order to implement the protocol. The standard is in natural language so a formal language is needed to describe its behavior. A prototype has also been created to simulate the protocol behavior.The protocol has been tested on a real environment, using PCs and LEON as primary and secondary stations, and different physical layers, serial cable, radio frequency and GSM.

Solutions in the field of Ambient Assisted Living (AAL) do not generally use standards to implement a communication interface between sensors and actuators. This makes these applications isolated solutions because it is so difficult to integrate them into new or existing systems. The objective of this research was to design and implement a prototype with a standardized interface for sensors and actuators to facilitate the integration of different solutions in the field of AAL. Our work is based on the roadmap defined by AALIANCE, using motes with TinyOS telosb, 6LoWPAN, sensors, and the IEEE 21451 standard protocol. This prototype allows one to upgrade sensors to a smart status for easy integration with new applications and already existing ones. The prototype has been evaluated for autonomy and performance. As a use case, the prototype has been tested in a serious game previously designed for people with mobility problems, and its advantages and disadvantages have been analysed.

Abstract.Nowadays there is a research on ambient living and smart building applications to make people life more confortable. This kind of applications, in general, requires the position where a person is in a building to act according it and to any physical parameters that are measured from the person, to determine, for instance, if the air condition has to be switched on or off, the room temperature has to be put up or down or the music has to be changed from classical to pop, or vice versa. This paper presents an indoor position solution based on BitCloud Stack, a full-featured, second generation embedded software stack from Atmel.

Abstract. TAIS group has developed an indoor position system prototype based on a fingerprint positioning algorithm. The prototype uses IEEE 802.15.4 mote and BitCloud Stack, a full-featured ZigBee Compliant, second generation embedded software stack from Atmel. The design requirements of the prototype were only to determine the actual position in a room of a user in a building, so the prototype accuracy is room accuracy. TAIS group decided to compete in the second edition of EvAAL Competition. This paper presents all the step made to adapt the prototype to the EvAAL environment, the found drawbacks and the obtained results. One of the most important drawback was that the Smart House Living Lab of the Polytechnic University of Madrid has only two rooms, the required accuracy was meters (error less than or equal to 0,5 meters the higher score, higher than 4 meters no score) and the room accuracy was substituted by areas of interest so the behavior of our prototype was going to work was an incognita.

Abstract. Since the electric generating, distributing and marketing has been possible; the Electric Meter was introduced and developed along the years, but never like this time. The digital technology, the wireless communication, and the computer systems have dramatically changed the Electric meter generation from Traditional Meter to Automatic Meter and now to Smart Meter. Their differences lie in how to collect and process information, and the amount of information they can provide. Even so the traditional meter reading has been long used, and it is still one of the most common ways for meter reading. This method, however, has their disadvantages which are the result of human basis reading method that uses. If the reading problem is solved by adding a simple circuit, which makes it automatic it will be still useful method of reading. In this paper it is described a prototype for Automatic Meter Reading (AMR) system that uses a Traditional meter, ZigBee modules, and Mesh network. As result the system gives, full capability of automatic meter even some features of smart meter too. This experiment has an important result for developing country like Ethiopia, which almost 99% its meters are the Traditional meters.
