Bluetooth scatternet technology was conceived to provide support for ad hoc multihop networking applications. Many theoretical works in the literature have been dedicated to optimize the formation and operation of Bluetooth scatternets. However, the performance of a real scatternet strongly relies on the implementation of the Bluetooth stack in the interfaces of the network nodes. By analyzing the...
Increasing the applicability of ubiquitous computing, minimizing energy consumption and hardware cost are mandatory in real world applications. In this paper we present our platform prototype for ubiquitous computing, which has been implemented based on commercial Bluetooth off-the-shelf components. It allows every object to be augmented with processing and communication capabilities in order to make...
To further increase the applicability of Bluetooth in real applications, reducing the energy consumption and hardware cost are important research topics. In this paper we examine the trade-off between power consumption and performance for our experimental prototype, which has been implemented based on commercial Bluetooth off-the-shelf components. Performance analysis shows that the use of the sniff...
Ubiquitous computing refers to making many computing devices available throughout the physical environment, while making them effectively invisible to the user. To further increase the applicability of ubiquitous computing, minimizing energy consumption and hardware cost are mandatory in real world applications. In this paper we present our platform prototype for ubiquitous computing, which has been...
This paper describes the development of a remote monitoring system for ECG signals. In order to achieve this goal in an economic way, we suggest the implementation of portable monitors based on consumer products such as PDA and digital acquisition cards. Several patient health monitoring scenarios where this platform may be applied are outlined, and a versatile system architecture design to fit them...
