In this paper we present a location service for Beacon Vector Routing (BVR), a point-to-point routing scheme for wireless sensor networks. A location service is necessary for decoupling the static node identifiers and dynamic BVR coordinates. This allows a node to use unique identifiers when communicating with a destination node, instead of using coordinate information directly. Our scheme uses...

We have designed and implemented a Web service for location discovery (LODS) and a location-based printing service that uses LODS on a network with wireless LAN connectivity based on IEEE 802.11 that is typical to campuses and enterprises. The need for location management and location-based services is linked to the mobility of the users. While location discovery is already implemented in cellu...

Mobile computers and communication devices are establishing themselves as ubiquitous features of daily life. This development is linked to tremendous growth in the number and sophistication of mobile and mobile-aware software applications. Increasingly, such applications need access to information about their own and other objects' physical locations, a requirement known as location-awareness. ...

Mobility is key to personal freedom. With the increasing availability of mobile devices, many providers begin to offer location-based services. Although these services greatly enrich our mobility experiences, with them also comes the privacy concerns, as a location-based service provider now can continuously track the location of a user. This tracking may allow unauthorized access and cause ser...

So far, many types of location models have been developed to find optimal spatial patterns according to different spatial metrics such as cost, coverage and availability.  The initial focus of these models is on the location availability of service providers and demand estimates, and some of these models are within the framework of multi-objective programming models.  After the advent of scienc...

The ubiquity of cellphones has lead to the introduction of location-based services, which are services tailored to the current location of cellphone users. For example, a cellphone user can retrieve a list of interesting, nearby places, or parents are notified when a child (i.e., her cellphone) leaves a boundary area. Location is a sensitive piece of information, so location-based services rais...
