Implementação de técnicas de resolução de conflitos para sistemas ubíquos com suporte de comunicação de grupo

Abstract

The use of mobile devices is becoming increasingly popular. Embedded computing is becoming more powerful and, consequently, increasing their functions. The integration of these computers is a tendency for the future. Connecting these devices and building a transparent environment for the user is the mission of the ubiquitous computing. However, characteristics of these devices (such as heterogeneity, battery dependency, mobility, and connection instability) cause serious issues for an ubiquitous system. In this work, solutions using group communication to solve issues related to dynamism, mobility and connection instability are implemented. With the use of group communication it is possible to provide a better transparency against the issues caused by the use of mobile devices and, also, increase reliability through fault tolerance.
