In addition, we demonstrated the feasibility of effective to use wireless links when we consider the large battery-powered T-Sensor node with simulation analysis using number of pervasive devices in the environment.

This is especially true in the telematics field where WSN based Vehicle Detection Sub-system and management WSNs can be used to provide useful information such as road sub-system as shown in Fig. The WSN-based VDS is designed to detect the occupancy of a parking lot and report the result to the management sub-system.

T-Sensor node software block diagram BS. Each T-Sensor node has a magnetic sensor to detect ferrous materials in a vehicle. When a car approaches a parking lot, T-Sensor node detects the car and notifies the detected events to the T-Sink node. When the car is moving out from the parking lot, the event is detected by T-Sensor node and forwarded by T-Sink nodes.

The details of the routing protocol are explained at the end of this section. When the vehicle is moving out of the parking lot, the Figure 4. The T- state machine and a calibration algorithm.

An instant with a magneto-resistive sensor to detect ferrous materials in a detection flag is acquired by comparing the sample value to the vehicle.

However, through analysis and simulation, we self-healing when there occur routing problems. Then, the architecture is briefly described. Subse- quently, a case study is presented, describing how SYLPH has been used to define a wireless infrastructure into a tele-monitoring home care scenario. Finally, the results and conclusions are presented, including future lines of work.

Ambient Intelligence has an influence on the design of proto- cols, communications, systems integration and devices [13]. This kind of interaction is achieved by means of technology that is embedded, per- vasive, non-invasive and transparent for users, with the aim of facilitating their daily necessities [1].

Thus, it is necessary to provide efficient solutions that allow building Ambient Intelligence environments.

These environments require context- aware technologies to acquire data and intelligent systems to transform the data into knowledge.

One of the key aspects for the construction of Ambient Intelligence environments is obtaining context information through sensor networks. There are different tech- nologies for implementing wireless sensor networks, such as ZigBee, Bluetooth or Wi-Fi [12] [14]. However, their main problem is the difficulty for integrating devices from different technologies in a single network [3].

Another key aspect is the knowl- edge management, and this can be done by means of distributed systems and architec- tures, as for example SOA. Moreover, in those pro- posals it is not enough considered the necessity of minimize the overload of the ser- vices architecture on the devices. Further- more, as said above, SYLPH considers the possibility of connecting multiple WSNs based on different radio and link technologies [13], whilst other approaches do not.

One of the priorities of the Ambient Intelligence is health care. There are several health care developments for tele-monitoring based on WSNs [9]. However, these D.

Tapia et al. SYLPH has been designed in order to face some of these issues. As indicated in the next section, SYLPH is an architecture that enables the integration of WSNs focusing on providing a greater simplicity of deployment and optimizing the reutilization of the available resources in such networks. The main objective is to distribute resources over multiple WSNs by modeling the functionalities as independent services. A service oriented approach has been chosen because such architectures are asynchronous and non-dependent on context i.

It is important to mention that the main objective of this paper is not to make an extensive description of SYLPH11 but its use for Ambient Intelligence envi- ronments, such as the home care scenario described in the next section. SYLPH can be executed over multiple wireless devices independently of their microcontroller or the programming language they use.

SYLPH works in a distrib- uted way so that the most application code does not have to reside only on a central node. Thus, a node designed over a spe- cific technology can be connected to a node from a different technology. In this case, both WSNs are interconnected by means of a set of intermediate gateways connected simultaneously to several wireless interfaces.

SYLPH allows applications to work in a distributed way and independently of the lower layers related to the wireless sensor networks formation and the radio transmission amongst the nodes that conform them.

These layers are added over the application layer of each WSN stack. SSDL describes the service itself and its parameters to be invoked. The SSD is used as a directory of the services offered by the network nodes. In such figure can be seen the protocols that allow the peer-to-peer interaction between layers of the same level at the two wireless devices. Thus, it can forward messages amongst the different networks to which it belongs.

The interconnection of the different WSNs is transparent to the service invoking. Figure 3 is an example of this approach. When the ZigBee node D. The system makes use of several wireless sensor networks for obtaining context information in an auto- matic and ubiquitous way.

A network of ZigBee devices are installed all over the home of each dependent patient to be monitored. Amongst the deployed ZigBee sen- sors there is a remote control carried by the monitored person that also includes a button which can be pressed in case of remote assistance or urgent help. Moreover, there is a set of ZigBee sensors for controlling the environment light, smoke, tem- perature, etc.

Furthermore, there are several ZigBee actua- tors that physically respond to the changes in the environment e. Finally, biomedical sensors [13] will allow the system to acquire con- tinuously data with the vital signs of the patient. In this case, each patient carries three different sensors: an ECG Electrocardiogram monitor, an air pressure sensor acting as respiration monitor and a MEMS Micro-Electro-Mechanical Systems triaxial accelerometer for detecting falls.

There is also a computer connected to Internet and to a remote health care cen- tre. This computer also acts as a ZigBee master node through a physical wireless interface.

On the other hand, the computer is the master node of a Bluetooth piconet i. Furthermore, it acts as a SSD and the rest of the nodes can register their own services. In this case, a smoke sensor detects a smoke level higher than the specified threshold. Then, the sensor invokes a service offered by the node which carries the fire alarm, making it to ring.

At the same time, it also invokes a service offered by the master node, which sends an alarm through the Internet towards the remote health care centre. The caregivers can establish a communication over VoIP or by means of a webcam at home in order to check the incidence.Cp represents average current consumption for of magnetic variation of the distortion from the base-line in signal processing with the MCU.

Moreover, qualitative high-medium-low values, besides generating the loss of information, introduce subjectivity to metrics. A service oriented approach has been chosen because such architectures are asynchronous and non-dependent on context i. Ricci, A.
