    A fixed Bluetooth transmitter can offer mobile services to people in proximity. However, the Bluetooth device discovery process introduces a significant delay, which impacts usability. A number of solutions have been proposed for bypassing device discovery; in this paper we propose a new technique leveraging multimodal user interfaces. In our approach, someone coming into range of proximity-based ... View full abstract»

    Determining the location of mobile devices is a necessary system function for a growing number of location based services (LBS). The most popular method for location determination is GPS, however GPS has known accuracy and environmental limitations, many of which are exacerbated in dense urban areas. Wireless positioning systems (WPS) on the other hand, demonstrate location accuracy largely invert... View full abstract»

    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1363 KB) | HTML iconHTML

    Many location-based systems rely on fine-grained tracking of mobile objects that determine their own locations with sensing devices like GPS receivers. For these objects, energy is a very valuable and limited resource. A distance-based reporting protocol can be employed to reduce the energy they consume by sending position updates. However, the energy required for position sensing has not been con... View full abstract»

    Mobile terminals with built-in GPS receivers are becoming more and more available, thus the public deployment of location-based services (LBS) becomes feasible. Upcoming LBS are no longer only reactive but getting more and more proactive, enabling the users to subscribe for certain events and get notified when e.g. a friend approaches or a point of interest comes within proximity. However, power c... View full abstract»

    This paper discusses the design and implementation of an ultra low power embedded GPS receiver node for use in remote monitoring situations where battery life is of the utmost importance. The power consumed by a GPS radio is high when compared to other typical components of sensor networks. We offer several hardware and software solutions to prolong the battery life while preserving a required GPS... View full abstract»

    Mobile object tracking is the process of tracking objects which are moving constantly in their environment and thus change their location and context. We present in this paper a decentralized data management solution based on peer-to-peer (P2P) concepts and in particular a distributed hash table (DHT). Sensor network nodes run a DHT system, to which tracked objects or sensors insert their data abo... View full abstract»

    In this paper we propose two algorithms for efficient data-centric storage in wireless sensor networks without the support of any location information system. These algorithms are intended to be applied in environments with large number of sensors where the scalability of the network has great issue.

    Conventional entity authentication is not enough to build a secure pervasive computing environment. Being sure that you are talking to the expected entity does not guarantee it is going to do what you expect him to do, and only that. This paper introduces a concept of "trustworthy authentication" in pervasive computing which is defined as entity authentication accompanied by an assurance of trustw... View full abstract»

    Mobile sensors are useful in many environments because they can move to increase the sensing coverage. In this paper, we present a mobile sensor prototype in which the Mica2 sensor node is used to control the movement of the robot built with commercial off-the-shelf (COTS) components. We use a sensor relocation application to demonstrate the feasibility of our design. In the sensor relocation appl... View full abstract»
