Internet-das-Bionano-Coisas: Conectando-se às Nanomáquinas

The Internet-of-things attracts the attention of many researchers in computer networks with the challenge of providing connectivity to a huge quantity of devices. This reality can be further complicated once again with the recent proposed Internet-of-bionano-things. Nanomachines, natural or synthetic, will be able to communicate to each other and to the Internet through the means of communication systems that are being developed at the nano-scale with the goal of cooperatively executing complex tasks. This technology requires a complete revision of the TCP/IP architecture to accommodate the requirements and demands of the nanonetworks. This chapter aims at introducing this research field to the computer network community, presenting the different types of communicating networks, an initial reformulation of the TCP/IP architecture, research challenges and the applications for the nanonetworks. This technology enables a revolution in the society and affects directly areas, such as medicine, agriculture, pollution and even industry

A first study on video transmission over a nanowireless network

International audienceVideo streaming is a growing application on the Internet, and its growing pace is not slowing down. There have been a tremendous amount of work on video streaming over the Internet but nobody has ever studied in detail video streaming over a nano-wireless network. We think that video streaming could be a potential application for nano-wireless networks and we know that video streaming is a challenging application for networks. First, video streaming is a real-time transmission meaning that it is sensitive to delay and jitter. Second, it is often better not to retransmit losses to avoid video freezing. That is why nano-wireless layers will probably have to be tuned for video streaming.This article studies, through simulation, different scenarios of video transmission over a nanowireless network. We conclude that research needs better tools and models for such studies
