With peta-bytes of data that are continuously collected about various aspects of the Internet, how hard can it be to obtain an accurate picture of its traffic, its physical topology (i.e., router-level Internet), its logical overlays (e.g., the Web, online social networks), or its “dark” sides and associated activities (i.e. cyber crimes)?
Radio-frequency based wireless communications have revolutionized our society. Thanks to important wireless communication technologies such as Wi-Fi, LTE, and so on, people can enjoy high data rate and pervasive connections while surfing the Internet.
The operators of the Autonomous Systems (ASes) composing the Internet must deal with a constant traffic growth, while striving to reduce the overall cost-per-bit and keep an acceptable quality of service.
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.
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.
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.
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 rapid growth of wireless mobile devices has led to saturation and congestion of wireless channels – a well-known fact.
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.
