In this paper, we propose a new location service for Ad hoc mobile networks. The network area is divided into non-overlapping zones. Using a hash function, a node identifier is mapped to a set of zones, in which the location information of the node are stored. We also propose a location information distribution scheme that achieves low rate of outdated location information. Using cross-layer de...

Considering the recent convergence of computing and telecommunications technologies with the tremendous success of the Internet, the World Wide Web, and Mobile Communications, the next step is expected to be the Mobile Web. The main promise of the Mobile Web is to satisfy user needs for anywhere, anytime access to information and services, including Location Based Services (LBS). This paper pre...

The Service Location Protocol (SLP) is a proposed standard from IETF. It provides a flexible and scalable service discovery framework in IP network, and it can work with or without a directory service. This paper presents mSLP Mesh-enhanced Service Location Protocol. mSLP proposes to use a fully meshed peering Directory Agent (DA) architecture. Peer DAs exchange service registration information...

Location based services are information and entertainment utility using specific controls for location and time available through mobile devices. One type of location-based service is near location-based service, in which local-range technologies such as Bluetooth, WLAN, and infrared technologies are used to match devices to nearby services. This application allows a person to access informatio...

In this paper, we propose a novel location technology-based shopping service system (LSSS); describe its design methodology and implementation detail. LSSS incorporates handheld terminals, resource management system and wireless location technology together to make a whole system. The service provided by the system can make customers in a shopping mall conveniently get product information, noti...

In the last decade, Grid Computing and Pervasive Computing paradigms have emerged and rapidly affirmed. These two worlds, however, can no longer be separated islands. As a matter of fact, traditional grids are moving towards Pervasive Grid environments and, as a result, they benefit from both grid and mobile technologies. In particular, a key feature of the Pervasive Computing paradigm, like th...

This position paper introduces the Globe object model for wide-area distributed systems and its location service. The location service provides transparency of location, migration, distribution, and replication of distributed objects. We present the architecture of the service and briefly discuss scalability.
