The future of the Internet is social

17 Aug

Fear and ignorance of the technology produces an technophobia that preventsecousin them from seeing the great strides that the internet and other technologies provide, a recent study published in the IMDEA site shows that the future of the Internet is social.

The work was done by IMDEA Networks Institute who announced the successful completion of its Content Distribution Research projects done by the European Advanced Institute of Social Information (eCOUSIN – enhanced Content Distribution with Social Information).

The findings of the project gather data from the purpose of the research, the agreement made between employees of the European Commission that it had as main objective to create an innovative network architecture that improve the efficiencies of online social networks, as well as provide a quality experience users.

The idea of ​​the project was to explore the growing popularity of social content online and their interdependencies, focusing on data collection and analysis, the scalability of the network infrastructure, connecting features related to the contents, and guided by social information through algorithms projects.

Nine partners from six countries and four universities participated in the project, including IMDEA based in Madrid, which contributed passive and light measurement tools, performance models, and predictors of mobile networks, as well as algorithms for resource allocation optimization.


The Internet of Things benefit the development

30 Jun

The potential economic value of the Internet IoTof Things (IoT) is being widely underestimated, and it could be worth more than $ 11 trillion a year, according to a new report by the McKinsey Global Institute, see in Washington Post.

The Trade Marks Registry gives six reasons why the IoT is being underestimated, which includes the sub-use of data generated by various sensing devices and other networked devices.

According to the institute’s analysts paint a big-picture economic outlook, seen exclusively in industrial sectors, while there is the primary concentration of opportunities in the market to Consume Commerce (business-to-consumer) of IoT and is missing a potentially much larger opportunity the business-to-business.

In addition, about 40% of the IoT’s economic value is fed by the interoperability device, which obviates the revenue opportunity in software and hardware for this.

McKinsey also argues the impact of the Internet of Things on world economies in development are underestimated and that these savings benefit of about 40 percent of economic gains compared with about 60 percent share of the developed world due to a mistaken view this is only for the advanced world.
McKinsey speculates some developing countries will be able to overcome the advances in developed countries because the installation of equipment or infrastructure with sensors and actuators will become a problem solved.
Finally, the Internet of Things will support new business models that are likely to correlate with how data is tracked and evaluated in real time, making the frontiers of technology and and no-tech companies can not be confused.


If becomes unsafe biometrics

Networking of things: 5G

10 Dec

internetOfThingsSo far the connections were being upgraded to improve the performance of telephone between people, but the IoT (Internet of Things) is coming up with 5G connections and this can cause an even greater transformation.
We point in our blog (see smart cities or smart cities) that a greater connection between people and things could facilitate the daily lives of people, but now the idea is to connect us to our everyday objects.
This scenario will be fully ready in no more than six years, and now scientists, governments and communications companies make plans for the use of 5G communication from 2020.
Most experts believe that this will multiply by 10 the connections between people and objects, says Sara Mazur to BBC News: “Before there was talk that by 2020 there would be 50 billion devices connected to the internet, it is now believed that this figure is cautious,” it is research director at Ericsson, one of the communications companies that are developing the 5G.
In 2013 Samsung announced Samsung announced in 2013 that was experiencing the 5G connection to 1 gigabit per second (Gbps), and this means downloading a movie in HD in just one second with this connection, the future has arrived.
