Many users face surveillance of their Internet communications and a significant fraction suffer from outright blocking certain destinations. Anonymous communication systems allow to conceal the destinations they communicate with, but do not hide fact that are using them. The mere use such may invite suspicion, or access them be blocked. We therefore propose Cirripede, system can used for unobservable with Cirripede is designed deployed by ISPs; it intercepts connections clients...
Software-defined networking (SDN) and network function virtualization (NFV) processed in multi-access edge computing (MEC) cloud systems have been proposed as critical paradigms for achieving the low latency requirements of tactile Internet. While virtual functions (VNFs) allow greater flexibility compared to hardware-based solutions, VNF abstraction also introduces additional packet processing delays. In this paper, we investigate practical feasibility NFV with respect Internet...
The first release of 5G technology is being rolled out worldwide. In parallel, 3GPP constantly adding new features to upcoming releases covering well-known use cases.

A key challenge in censorship-resistant web browsing is being able to direct legitimate users redirection proxies while preventing censors, posing as insiders, from discovering their addresses and blocking them. We propose a new framework for called CensorSpoofer that this by exploiting the asymmetric nature of traffic making use IP spoofing. de-couples upstream downstream channels, using low-bandwidth indirect channel delivering outbound requests (URLs) high-bandwidth downloading content....
Researchers have proposed many wireless MAC protocols such as [20], [8], [25], [24], [6], and [17] which exploit frequency-agile radios multiple available channels to increase network through-put. These usually only require each node one radio. By carefully coordinating the frequency hopping of different nodes, pairs can use simultaneously. In [17], Mo et al classified these into four generalized categories compared their performances through both analysis simulation. They found that...
Future communication systems, such as those enabling the Tactile Internet, will face disruptive changes compared to state-of-the-art which are 1) highly dynamic topology changes; 2) replacement of end-to-end paradigm by real mesh topologies; and 3) a massive number devices. To overcome these changes, future systems substitute specialized hardware with generic boxes softwarization paradigm. Furthermore, this approach allow for quick deployment new services, was known cloud service already. In...

Fulcrum Random Linear Network Coding (RLNC) combines outer coding in a large Galois Field, e.g., GF(28), with inner GF(2) to flexibly trade off the strong protection (low probability of linear dependent coefficients) GF(28) low computational complexity GF(2). However, existing RLNC approaches are generation based, leading packet delays due joint processing all packets encoder and decoder. In order avoid these delays, we introduce Sliding Window (FSW) coding. We two flavors FSW: Nonsystematic...
