IntroductionIntroduction Technological topics:
Miniaturization of computational devices: advances in communication technologies; wide range of applications in several fields.
Scenarios where communication is more localized: without the need of the Internet infrastructure.

Paper ObjectivePaper Objective An approach for supporting P2P collaborative
communication based on learning profile. share and exchange learning objects; it is considered the learning profile and topics of interest of the
students involved in the process; a relationship between the learning profiles and the learning
objects is drawn upon the linkage of student’s learning preferences and fields of the fields.
Two application was developed: Mobile: Android platform using Bluetooth technology to
evaluate the proposal. Cloud: to retrieve learning objects, their respective metadata
and the student’s learner profile from an Amazon cloud to the device.

Learning ProfileLearning Profile The learning style involves the strategies that a student tends to
apply frequently to a given teaching situation. The Felder-Silverman Learning Style Model is describe by
dimensions of Learning and Teaching Styles, creating a relationship to learning styles and teaching strategies that could be adopted to support the student learning style.
The Felder-Silverman model was selected to this work, because it's close relationship to learning styles and teaching strategies, resulting in an adherence between these aspects.

Learning ObjectLearning Object It can be defined as an entity to be applied in a teaching-
learning process. e-learning: the aim is to create contents in digital formats.
Metadata usually is adopted to organize learning objects, improving their reuse.
The LOM (Learning Object Metadata) standard of the Institute of Electrical and Electronics Engineers – IEEE is the metadata specification used in the area of learning objects. It has a structure that describes learning objects through
descriptor categories.

Collaborative CommunicationCollaborative Communication Two types:
Local level: considers a collaborative communication when the most
of the features to support collaboration occurs at local level;
functions such as routing, name service, finding context and message forwarding are performed without the use of a global network infrastructure.
Global infrastructure: uses a global infrastructure (Internet, for
example) adopting the services provided by such infrastructure.

The ApproachThe Approach
Requirements: The student learning profile is:
a part of student model and splits the student learning profile into three categories, based on Felder and Silverman dimensions: Perception, Participation e Presentation Format
The learning objects available on the collaborative communication must be cataloged using LOM standard.

The ModulesThe Modules
Context Manager is responsible for providing the communication and the interaction between both P2P elements of the application: client and server. In the server side it deals with the matching and
retrieval procedures whilst in the client side it presents the learning objects retrieved from the server.
Object Sharing Manager manages the object sharing between applications and devices, wrap and unwrap objects; and save and request objects.
A prototype of e-learning P2P was implemented in an Android platform. Bluetooth API was used for implementing the functions of
communication as forwarding messages, service names and routing.
First step: download the LO, their respective metadata and the student’s
learner model, stored in a local repository; Web Collaborative Learning – WCL (cloud application): hosted in an Amazon cloud and uses the SQLite database 3.6.20.
