Mobile devices are increasingly being relied on for tasks that go beyond simple connectivity and demand more complex processing. In cases where such processing exceeds [...]

In this talk, I will present our recent work in the area ofknowledge bases. It covers 4 areas of research around ontologies andknowledge bases: The [...]

We investigate coupling from the past (CFTP) algorithmsfor closed queueing networks. The stationary distribution has a productform only in a very limited number of particular [...]

The major issue of indoor localization system is the trade-off between implementation cost and accuracy. A low-cost system which demands only few hardware devices could [...]

Motivated by improved models for content workload prediction, in this paper we consider the problem of dynamic content allocation for a hybrid content delivery system [...]

One vision for wireless networks has been the creation of wireless multihop networks that are formed and operate in a fully decentralized manner using cheap [...]

Recently there has been a significant interest in building big data systems that can handle not only "big data" but also "fast data" for analytics. [...]

The broadcast/cellular cooperation for a common delivery of Mobile TV is at the heart of the emerging mobile broadcast technologies, namely the mobile extension of [...]

Resource poverty is a fundamental constraint that severely limits the types of applications that can be run on mobile devices. This constraint is not just [...]

Increased user concern over security and privacy on the Internet has led towidespread adoption of HTTPS, the secure version of HTTP. HTTPS authenticatesthe communicating end [...]

Content caching is a fundamental building block of the Internet. Caches are widely deployed at network edges to improve performance for end-users, and to reduce [...]

We evaluate the performance perceived by end-users connected to a backhaul link that aggregates the traffic of multiple access areas. We model, at flowlevel, the [...]

: The Internet heavily relies on Content Distribution Networks and transparent caches to cope with the ever-increasing traffic demand of users. Content, however, is essentially [...]

The video part of Internet traffic is booming due to the ever increasing availability of video content from sitessuch as YouTube (video sharing), Netflix (movie [...]

 Abstract: In this talk we present new results on the stochastic bandit problems with a continuum set of arms and where the expected reward is [...]

In this work we analyze the estimation of the spatial reuse of a wirelessnetwork equiped witha Medium Access Control (MAC) mechanism based on 802.11's DistributedCoordination [...]

Simplicial complex representation gives a mathematical description ofthe topology of a wireless sensor network, i.e., its connectivity andcoverage. In these networks, sensors are randomly deployed [...]

Today, Internet users are mostly interested to consume content, information and services independently from the servers where these are located.Information Centric Networking (ICN) is a [...]

Web content coming from outside the ISP is today skyrocketing, causing significant additional infrastructure costs to network operators. The reduced marginal revenues left to ISPs, [...]

Cellular operators count on the potentials of offloading techniques to relieve their overloaded data channels. Beyond standard access point-based offloading strategies, a promising alternative is [...]

We propose a unified methodology to analyse the performance of caches (both isolated and interconnected), byextending and generalizing a decoupling technique originally knownas Che's approximation, [...]

We formulate optimization problems to study how data centers might modulate their power demands for cost-effective operation taking into account various complexities exhibited by real-world [...]

The adoption of Service Oriented Architecture (SOA) and semantic Web technologies in the Internet of Things (IoT) enables to enhance the interoperability of devices by [...]

Organic Computing has emerged almost 10 years ago as a challenging vision for future in-formation processing systems, based on the insight that already in the [...]

Applications hosted within the datacenter often rely on distributed services such as Zookeeper, Chubby, and Spanner for fault-tolerant storage, distributed coordination, and transaction support.  These [...]

Security and privacy are fundamental concerns in today's world. These concerns have become particularly prominent with Snowden's revelationsof the presence of the NSA in our [...]

The increasing mobile data demand and the proliferation of advanced handheld devices place the user-provided networks (UPNs) at a conspicuous position in next-generation network architectures. [...]

We assume a space-time Poisson process of call arrivals on the infinite plane, independently marked by data volumes and served by a cellular network modeled [...]

Quantitative evaluation plays a key role in the design of a broad range of systems, where functional and non-functional properties have to be carefully analysed [...]

Consider an irreducible continuous time Markov chain with a finite or a countably infinite number of states and admitting a unique stationary probability distribution. The [...]

This paper asks how can we better design urban environments, leveraging networked technologies to facilitate rich engagement by its inhabitants. It discussed the recent history [...]

There are known two "ALOHA-type" models, (a) with a finite number of queues and with messages ahead of each queue being potentially "active", and (b) [...]

Workshop 2014

Locator(Loc)/identifier(ID) Separation(LIS) was conceived to mitigate the explosion of the DFZ routing table. To be literally exact, every host would be given a Loc in [...]

The Tandem Jackson Networkis a system of n sites (queues)in series, where single particles (customers, jobs, packets, etc.) move, one by one anduni-directionally,from one site [...]
