ABSTRACT Context-awareness is viewed as one of the most important aspects in the emerging pervasive computing paradigm. Mobile context-aware
applications are required to sense and react to changing environment conditions. Such applications, usually, need to recognize,
classify and predict context in order to act efficiently, beforehand, for the benefit of the user. In this paper, we propose
a mobility prediction model, which deals with context representation and location prediction of moving users. Machine Learning
(ML) techniques are used for trajectory classification. Spatial and temporal on-line clustering is adopted. We rely on Adaptive
Resonance Theory (ART) for location prediction. Location prediction is treated as a context classification problem. We introduce
a novel classifier that applies a Hausdorff-like distance over the extracted trajectories handling location prediction. Since
our approach is time-sensitive, the Hausdorff distance is considered more advantageous than a simple Euclidean norm. A learning
method is presented and evaluated. We compare ART with Offline kMeans and Online kMeans algorithms. Our findings are very promising for the use of the proposed model in mobile context aware applications.

    ABSTRACT: With the rapid growth of socio-technical ecosystems, smart interactions and services are permeating every walk of life. As smart interactions must managed automatically and interactively in response to evolving user’s matters of concern, the smart Internet requires creative approaches where services and interactions are implemented with awareness of, and dynamic adaptation to, users, computational environments, changing policies and unknown requirements. Consequently, modeling and managing dynamic context is critical for implementing smart services and smart interactions effectively. Thus, smart interactions need infrastructure to acquire, compose, and distribute context information to multiple execution endpoints. Moreover, context management must be controlled and governed to optimize system properties. This chapter surveys context modeling and management approaches intended for the optimization of smart interactions and services, discusses the main challenges and requirements of context-awareness in the smart Internet, and provides a feature-based framework useful for the evaluation and implementation of context modeling and management mechanisms.

    ABSTRACT: Predicting users' next location allows to anticipate their future context, thus providing additional time to be ready for that context and react consequently. This work is focused on a set of LZ-based algorithms (LZ, LeZi Update and Active LeZi) capable of learning mobility patterns and estimating the next location with low resource needs, which makes it possible to execute them on mobile devices. The original algorithms have been divided into two phases, thus being possible to mix them and check which combination is the best one to obtain better prediction accuracy or lower resource consumption. To make such comparisons, a set of GSM-based mobility traces of 95 different users is considered. Finally, a prototype for mobile devices that integrates the predictors in a public transportation recommender system is described in order to show an example of how to take advantage of location prediction in an ubiquitous computing environment.
