The ever-growing computation and storage capability of mobile phones have given rise to
mobile-centric context recognition systems, which are able to sense and analyze the context …

We introduce a system for sensing complex social systems with data collected from 100
mobile phones over the course of 9 months. We demonstrate the ability to use standard …

Longitudinal behavioral data generally contains a significant amount of structure. In this
work, we identify the structure inherent in daily behavior with models that can accurately …

Tracking strategies for mobile users in wireless networks are studied. In order to save the
cost of using the wireless links mobile users should not update their location whenever they …

In the next generation high-speed wireless networks, it is important to provide quality-of-
service (QoS) guarantees as they are expected to support multimedia applications. This …

The complexity of the mobility tracking problem in a cellular environment has been
characterized under an informationtheoretic framework. Shannon's entropy measure is …

Mobile wireless networks pose interesting challenges for routing system design. To produce
feasible routes in a mobile wireless network, a routing system must be able to accommodate …

The complexity of the mobility tracking problem in a cellular environment has been
characterized under an information-theoretic framework. Shannon's entropy measure is …

We explore various network layer concepts that play a crucial role in the design of mobile
networking systems. We show that mobility is essentially an address translation problem and …

Methods of balancing call registration and paging are developed in this paper. Given that
the probability distribution on the user location as a function of time is either known or can be …
