The main goal of this article is to map and review real time video streaming collaborative softwares, in order to analyze platforms that are also able to edit films. Real time high resolution film transmission (4k, 8k or above) results in the excess of data generated and, consequently, in a high value for investment in editing, storage and content...

In the recent years, the research community proposed several protocols and applications for opportunistic networking. A common assumption is that all nodes have pro social behavior and are willing to cooperate with the network. However, in opportunistic networking applications, this assumption can lead to degradations in the network performance. Pe...

In the recent years, the research community has proposed several protocols and applications for opportunistic networking. These protocols require that all users are willing to cooperate with the network. However, users could have selfish behavior, which can lead to degradations in the network performance. In this work, we propose an incentive mecha...

In Opportunistic Networks, instead of assuming an end-to-end path as in the traditional Internet model, messages are exchanged opportunistically when an encounter happens between two nodes. In the last years, several forwarding algorithms to efficiently decide when to forward messages were proposed. Those protocols are commonly suitable to a specif...

Project
The PORVIR-5G project is a project in cooperation between UFMG, UFES, UFRGS, UNISINOS and UNICAMP, which will investigate the future of the Internet in view of the new demands of 5G networks. The project will develop and demonstrate a communication network with its programmable fronthaul and backhaul, integrating wireless networks with optical network solutions, packet switched networks and cloud computing. The key technologies of the PORVIR-5G project are: (i) slicing of optical, wireless and packet networks, controlled by (ii) deep programmability interfaces, through which devices are configured by network functions to provide the necessary performance for future Internet applications, which allows for (iii) end-to-end and multi-layer orchestration, considering the quality of experience of applications running on the network. The project will validate and demonstrate the programmability and virtualization proposals in three demos, each supporting the key performance demands of 5G networks: (i) an Internet of Things demonstration focusing on massive communication between devices (massive machine-type communication); (ii) a demonstration of smart cities that demand reliable low-latency flows; and (iii) a demonstration of high-speed video transmission that demonstrates next generation broadband networks.
