This paper proposes an assessment model, based on a new taxonomy, which comprises an evaluation guideline with performance metrics and experimental setup to aid designers in evaluating solutions through fair comparisons. Simulation... more
Due to the increased capabilities of mobile devices and through wireless opportunistic contacts, users can experience new ways to share and retrieve content anywhere and anytime, even in the presence of link intermittency. Due to the... more
The Transmission Control Protocol - TCP has been widely researched in many different networking technologies such as wireless, optical, satellite, sensor, and wired since it is the most used protocol on the Internet. In Wireless mesh... more
The increasing demand of multimedia applications requires a new behavior of routing protocols for wireless mesh networks (WMNs). It is necessary to support the minimum requirements for quality of service (QoS), but WMNs also need to... more
This paper presents a proposal for dynamic control of Quality of Service (QoS) in optical networks based on optical burst switching (OBS) using a GMPLS control plane. In this proposal, monitoring agents are used to verify the QoS... more
ince users move around based on social relationships and interests, their imovement patterns represent how nodes are socially connected (i.e., nodes with strong social ties, nodes that meet occasionally by sharing the same working... more
The advances in the areas of microelectronics and telecommunications are helping to materialize the vision of a pervasive computing model through the incorporation of sensors and communication interfaces into objects of everyday life. In... more
Despite the evolution in deployed infrastructure and in the way that people access information, still there are those who are socially excluded and have no access to information due to their geographic location (e.g.,... more
