| Adapting User Interfaces (UI) while in mobility remains challenging as
contexts of use identification and changes can obviously not be finely
envisioned at design time. However, user's tasks, habits and preferences may be
context dependent. As a result, there is a need for managing context-aware
adaptation at runtime. This paper describes EMMA (Embedded Manager for Mobile
Adaptation), a running system that gathers data in mobility, learns key
contexts of use, and provides the end-user with relevant adaptation. The
process is based on a bayesian user model embedded on a Smartphone running
under Windows Mobile operating system. It is placed under the end-user's
control through a dedicated UI, called meta-UI. Besides this end-user's partner
role, EMMA can serve as a designer's partner tool for identifying the key
contexts of use in the wild. Keywords: Bayesian network, Smartphone, adaptation, clustering, context of use,

| To follow up our works on a service-oriented architecture dedicated to
context perception for the smart home [7], we present in this paper how to move
complex reasoning on top of the ontology. We focus on a multi-sensors data
fusion architecture using the Transferable Belief Model. High level symbolic
data are deduced using fusion from redundant, complementary and heterogeneous
sensors data. Symbolic data describe complex contexts and enable to provide
more contextualised services. To show the contribution of using the
Transferable Belief Model in context awareness systems we detail an experiment
about human posture characterisation using heterogeneous and uncertain sensors
data. Keywords: context, data fusion, dealing with uncertainty, sensors, smart home | |||
| Extraction de connaissances dans les réseaux ad hoc inter-véhicules | | BIBAK | Full-Text | 17-20 | |
| Bruno Defude; Thierry Delot; Jose-Luis Zechinelli Martini; Nicolas Cenerario; Sergio Ilarri | |||
| Our work focus on data management in Vehicular Ad Hoc Networks (VANETs).
Many pieces of information may be exchanged in such networks, for instance to
warn drivers when a potentially dangerous event arises (accident, emergency
braking, obstacle in the road, etc.) or to try to assist them (available
parking spaces, traffic congestions, real-time traffic conditions, etc.).
Existing systems only use the data exchanged to warn the driver. Then, the data
is considered obsolete and is deleted.
In this paper, we rather propose to aggregate the data once it becomes obsolete. Our objective is to produce additional knowledge to be used by drivers when no relevant data has been communicated by neighbouring vehicles. For example, it becomes so possible to dynamically detect potentially dangerous road segments or to determine the areas where the probability to find an available parking space is high when none has been received.

| SIMBA: méthodologie et plateforme de prototypage moyenne fidélité pour les systèmes interactifs mixtes | | BIBAK | Full-Text | 21-28 | |
| Wafaa Abou Moussa; Emmanuel Dubois; Christophe Bortolaso; Pascal Salembier; Jean-Pierre Jessel; Cédric Bach | |||
| In this paper, we present SIMBA, a prototyping approach dedicated to Mixed
Interactive Systems (MIS). This approach supports the use of an existing
co-design process of MIS. SIMBA combines a «medium fidelity»
prototyping platform based on simulation, and a model-driven development
process. Simulation-based prototyping allows for a fast and inexpensive
generation of mixed interactive prototypes. A model-driven development process
enables such prototypes to be tightly coupled with design choices established
in earlier design phases. It also supports an incremental evolution into the
final, not simulated, MIS. The prototyping approach that we present is based on
the identification of the roles of the different actors involved in a MIS
development process and the collaboration between them. An augmented museum
application is used throughout this paper to illustrate the proposed
prototyping approach. Keywords: développement incrémental, prototypage par simulation,

| Multi-ressources K-Médians: un algorithme de placement de services web sur les réseaux sans fils municipaux | | BIBAK | Full-Text | 29-36 | |
| Julien Gossa; Nipaul Long | |||
| Nowadays, numerous municipalities are laying free wireless Internet access
infrastructures on. These infrastructures are a natural target for the
deployment of Web services, such as mapping or multimedia content providing.
Regarding the number of clients, ensuring their performances represents one
particularly important challenge. Unfortunately, this challenge is hard because
of Web services peculiarities: difficult to migrate and replicate,
heterogeneous, and highly interdependent. Our proposal is an algorithm designed
to build deployment plans for sets of Web services, according to their
interdependency while ensuring performances and load balancing. We have shown
the efficiency of this algorithm, called MRKM for Multi-Resources K-Median, on
the Grid 5000 experimental platform. Keywords: deployment plan, k-medians, placement, web services | |||
| Composing interactive systems by planning | | BIBAK | Full-Text | 37-40 | |
| Yoann Gabillon; Gaëlle Calvary; Humbert Fiorino | |||
| User Interfaces (UIs) are mostly produced along a mental forward engineering
process consisting in step by step transforming abstract descriptions into more
concrete ones. Transformations make trade-offs between the context of use
(<user, platform, environment>) and the usability properties that have
been elicited as key. In ubiquitous computing, neither the context of use nor
the user's objectives can be set at design time: they may opportunistically
emerge with the arrival/departure of interaction resources and/or user's needs.
As a result, there is a need for dynamically composing interactive systems. We
explore multiagents planning for tackling the combinatory issue when sharing
interaction resources among interactive systems and UI elements. The gateway
between HCI and planning is performed using Model Driven Engineering (MDE).
Experience shows that MDE is powerful for chaining domains together as well as
for better understanding and improving domains languages. Keywords: IDM, IHM, composition dynamique, contexte d'usage, planification | |||

| Une approche robuste pour la prolongation de la durée de vie des réseaux ad hoc multimédias | | BIBA | Full-Text | 49-56 | |
| J. M. Bahi; M. Eskandar; A. Mostefaoui | |||
| In wireless ad hoc networks, nodes are energy constrained. As they communicate far off destinations using intermediate relays, it may not be in interest of a node to expend its energy in relaying and consequently reducing its own lifetime. On the other hand, if all nodes decide not to always accept relay requests, the network throughput will drop dramatically i.e., the lifetime of the whole network is reduced. Obviously, from a single node point of view, these two extreme attitudes are opposite to its interest. We addressed this issue by proposing a novel distributed approach that guarantees tasks affectation to nodes with regard to their energy constraints. The key idea behind is to guarantee to all nodes that they share tasks in function of their energy provisions. In this paper, we tackle the problem of nodes mobility and its impact on the behavior of our proposed approach. We evaluated the performance of our approach under several scenarios and showed that it still improves the network lifetime. | |||
| Construire des applications fiables à base de services mobiles | | BIBAK | Full-Text | 57-64 | |

| Along with the emergence of ubiquitous computing there is a need for
building reliable and secure applications that provide access to information in
a continuous way. In such a context, access to resources and applications must
be done in a flexible way through services that come up as a new paradigm for
programming and organizing operations. In this paper we present an approach for
building reliable mobile applications based on services oriented paradigm and
the use of a contract based coordination model. Thanks to contracts, it is
possible to associate a personalized behavior to a flow describing the logic of
a mobile services based application. Contracts ensure transactional properties
at execution time in the presence of exceptions and make applications aware of
their execution context (QoS). Keywords: application à base de services, comportement transactionnel,
coordination de services, propriétés non fonctionnelles | |||
| Un système d'apprentissage pervasif intégrant des activités de travail et de formation | | BIBAK | Full-Text | 65-72 | |
| Cuong Pham-Nguyen; Serge Garlatti | |||
| In the p-LearNet project, we are interested in TEL systems integrating
context-aware corporate learning and working activities for e-retail (shops and
hypermarkets). The main issues of the p-LearNet project are: work-integrated
learning and customer learning support whatever the place, the time, the
organisational and technological contexts of the individual or collective
learning and working processes. We propose an adaptive and context-aware model
of scenario for a pervasive learning system. This model enables us to choose
how to achieve activities according to the current situation. The scenario
model is based on a hierarchical task model having the task/method paradigm --
methods define how to achieve a task, a task represents an activity. The
context-aware adaptation process selects the relevant methods according to the
current situation. Keywords: adaptation, apprentissage pervasif, contextuel, modèle de
tâches hiérarchiques, paradigme tâche/méthode,

| We present in this paper the interest of ubiquitous computing for the so
called contextualized forums. These forums allow communities of practice
exchanging and sharing experiences or situations already lived by using
learning documents to classify these exchanges. These forums contain a lot of
information which contribute to improve classical training. We study here
ubiquitous computing possibilities to use this type of forums in order to
improve professional training to business process by helping the user to put
into practice his/her acquisition. The developed application is being tested
and works principally on smartphones. Keywords: assistance, contextualized forum, personalization, ubiquitous computing | |||

| Gérôme Canals; Pascal Molli; Julien Maire; Stéphane Laurière; Esther Pacitti; Mounir Tlili | |||
| This paper describes the demonstration of the XWiki Concerto system. XWiki
Concerto is a a P2P wiki that supports mobile users. Each XWiki server is the
network is extended with a replication manager that propagates local changes to
remote servers and merges concurrent changes. The demonstration is based on a
scenario in which different servers are used to concurrently edit a wiki page.
One of the servers is then disconnected from the network but continue to be
used to edit the page. The different copies are then reconciliated when the
server is reconnected. Keywords: P2P wiki, merge, mobile users, optimistic replication | |||

| The Network Mobility Basic Support (NEMO BS) protocol is the IETF standard
to support mobility of entire IPv6 networks. Every network movements are fully
transparent to the nodes located inside the mobile network without interruption
on their ongoing communications. In addition to the mobility support, a mobile
router may be equipped with several wireless network interfaces in order to
connect heterogeneous access technologies. These networks can be available at
the same time, and consequently the mobile network may benefit from these
multiple paths to connect the Internet. All access networks have different
characteristics in terms of bandwidth, latency, cost, etc. It is therefore
important to install flow policies on an embedded mobile network in order to
distribute, adapt or filter communications according to preferences of the
operator and the availability of the technologies. In this demonstration, we
propose to show how to apply flow policies on an embedded mobile network inside
a vehicule. Keywords: IPv6, flow management, mobile IPv6, network mobility basic support (NEMO BS) | |||
| Annotation contextuelle automatique avec PhotoMap | | BIBAK | Full-Text | 89-90 | |
| Windson Viana; Marlène Villanova-Oliver; Jérôme Gensel; Hervé Martin | |||
| We present a mobile and context-aware system, called PhotoMap that provides
semi-automatic annotation about the spatial, temporal and social contexts of a
photo. (i.e., where, when, who and what was nearby). The PhotoMap application
captures the photo shot context when a user takes a picture with her camera
phone. The mobile client gets the geographic position of the device, date and
time information, bluetooth addresses of the nearby devices. PhotoMap explores
these gathered metadata to infer high level contextual information such as,
nearby user's friends, weather conditions, device address, and nearby important
objects. PhotoMap uses these metadata for organizing, sharing and retrieving
the photo files. Keywords: FOAF, context, ontology, pervasive systems | |||
