The increasing deployment of small cells aimed at off-loading data traffic from macrocells in heterogeneous networks has resulted in a drastic increase in energy consumption in cellular networks. Energy consumption can be optimized in a selforganized way by adapting the number of active cells in response to the current traffic demand. In this paper we concentrate on the complex problem of how t...

A recent advancement was achieved in the integration and miniaturization of a binocular head-worn projection display (HWPD) conceived for fully mobile users. The devised display, referred to as Mobile HWPD (M-HWPD), offers see-through capability through custom-designed, light-weight projection optics and an integrated commercial-off-the-shelf (COTS) retro-reflective screen to display full color...

The emergence of small portable computers and the advances in wireless networking have made mobile computing today a reality. Information systems and databases are among the applications that make mobile computing attractive. While the topic of querying data in wireless and mobile systems has received a lot of attention, techniques to eeciently update data in these systems while providing trans...

Intraoperative radiation therapy (IORT) has been customarily performed either in a shielded operating suite located in the operating room (OR) or in a shielded treatment room located within the Department of Radiation Oncology. In both cases, this cancer treatment modality uses stationary linear accelerators. With the development of new technology, mobile linear accelerators have recently becom...

For training National Guard units the US Army National Guard will eld combat vehicle training simulators called Mobile Trainers Each National Guard unit must train at a station which is not farther than a speci ed maximum travel distance from its armory We address the problem of nding the optimum locations for the home bases for the mobile trainers the locations of secondary training sites to w...

Pathfinding is an important underlying task for many autonomous agents. Abstracting the environment into a navigation graph (e.g., a grid map) enables a mobile unit to plan its path to goal using heuristic search. For example, an A* search finds an optimal path. With multiple units moving simultaneously inside a shared space, the goal is to navigate each unit to its target without colliding int...

The paper deals with a generic model of a mobile agent network that includes multi-agent system, and a set of processing nodes connected by a communication network. A mobile agent network is described as a queuing system where mobile agents represent information units that must be served. Network flows related to agent hosting and migration and serving capabilities of processing nodes are propo...

RAMSES (Remote Archeological Mobile Support Enhanced System) is an outdoor application of mobile computing to eld archaeology, whose prototype has already been eld tested in Summer 1998 at the site of Poliochni in Greece. The requirements for both hardware and software are illustrated; the system is composed by a xed station, acting as object repository, and a few mobile units which input archa...
