To compete in sectors where the customer experience is increasingly digitized, companies are scrambling to expand their portfolio of innovations – from new products and enhanced processes to complementary services and new business models. In the process IT units are figuring out how to share responsibilities with, and coordinate the efforts of, internal stakeholder groups, such as marketing, operations and R&D, as well as the efforts of external parties, such as vendors, business partners, start-ups, and even individual contractors and hobbyists. This seminar will be an opportunity to learn about and discuss the most recent research insights from an MIT CISR research project on digital innovation.  

The talk will present concepts and basics of distributed computing which are important (at least from the presenter's point of view!), and should be known and mastered by researchers, and Master students. Those include: (a) a characterization of distributed computing (which is too much often confused with parallel computing); (b) the notion of a synchronous system and its associated notions of a local algorithm and message adversaries; (c) the notion of an asynchronous shared memory system and its associated notions of universality and progress conditions; and (d) the notion of an asynchronous message-passing system with its associated broadcast and agreement abstractions, its impossibility results, and approaches to circumvent them. Hence, the talk can be seen as a guided tour to key elements that constitute basics of distributed computing.

By 2025 ad fraud will be the second largest form of organized crime, resulting in losses of up to $1 trillion in damages to the society, creating an unprecedented burden to national economies and tax payers. In this talk you will gain deep insight in to various aspects of the problem; the three modes of ad fraud, money flows, botnet hunting, spam-site detection, adversary profiles and researcher safety. The talk is aimed at researchers, and includes many information that has never been disclosed to public.

While the IEEE 802.11 protocol has fostered ubiquitous connectivity for wireless users, it was not originally designed to efficiently handle voice or video traffic, which nowadays accounts for most of the Internet traffic.

Targeting an increasing number of potential application domains, wireless sensor networks (WSN) have been the subject of intense research, in an attempt to optimize their performance while guaranteeing reliability in highly demanding scenarios.

Multipath transport protocols like MPTCP transfer data across multiple routes in parallel and deliver it in order at the receiver. When the delay on one or more of the paths is variable, as is commonly the case, out of order arrivals are frequent and head of line blocking leads to high latency. This is exacerbated when packet loss, which is also common with wireless links, is tackled using ARQ.

Disculpa, pero esta entrada está disponible sólo en English.The rapid growth of wireless mobile devices has led to saturation and congestion of wireless channels – a well-known fact. In the recent years, this issue is further exacerbated by the ever- increasing demand for traffic intensed multimedia content applications, which include but are not limited to social media, news and video streaming applications.

Cellular service providers have been struggling with users’ demand since the emergence of mobile Internet. As a result, each generation of cellular network prevailed over its predecessors mainly in terms of connection speed.

The future of network communications is mobile as user's demand for ubiquitous connectivity increases. Wireless has become the primary access technology, leading to an explosion in traffic demand. This challenges network providers to manage and configure new requirements without incrementing costs in the same amount. In addition to the growth in the use of mobile devices, there is a need to operate simultaneously different access technologies.
