The infrastructure of mobile grid presents some challenges to allow the interaction between mobile devices and grid environments, such as (a) applications submission and monitoring facilities in an automated and coordinated manner, (b) disconnections during execution of applications, and (c) selection of suitable grid resources for their execution.

(UFSM) – 97105-900 – Santa Maria – RS – Brazil ABSTRACT Opportunistic Networks are able to exploit social behavior to create connectivity opportunities. This paradigm uses pair-wise contacts for routing messages between nodes. In this context we investigated if the " six degrees of separation " conjecture of small-world networks can be used as a basis to(More)
The identification of users in pervasive and ubiquitous environments can be performed using various devices and techniques, among which the use of wireless sensor networks (WSN), radio frequency identifiers (RFID), Smartphones, Bluetooth, among others. However, it is necessary to implement management techniques and control privacy of these heterogeneous(More)
Cities are involving towards intelligent dynamic infrastructures that serve citizens with new services to improve their quality of life and to fulfill the criteria of energy efficiency and sustainability. In this context, an important question is how to instrument citizens and cities to promote the sensing of data about different aspects. In this work, we(More)
Due to the nature of ubiquitous systems, nodes (e.g., Sensors) are frequently prone to failures. Such systems must, therefore, present self-healing capabilities in order to detect failures and make the necessary adjustments to prevent their impact on applications. In such a context, this work proposes a new and flexible unreliable failure detector, denoted(More)
