Creating Shared Secrets out of Thin Air

Christina Fragouli, Suhas Diggavi, Iris Safaka

Current security systems typically rely on the adversary's computational limitations (e.g., the fact that it cannot invert a hash function or perform large-integer factorization). Wireless networks offer the opportunity for a different, complementary kind ...

Topological Measure Locating the Effective Crossover between Segregation and Integration in a Modular Network

Ali Ajdari Rad

We introduce an easily computable topological measure which locates the effective crossover between segregation and integration in a modular network. Segregation corresponds to the degree of network modularity, while integration is expressed in terms of th ...

On the spatial partitioning of urban transportation networks

Nikolaos Geroliminis, Yuxuan Ji

It has been recently shown that a macroscopic fundamental diagram (MFD) linking space-mean network flow, density and speed exists in the urban transportation networks under some conditions. An MFD is further well defined if the network is homogeneous with ...

A Decentralized Online Social Network with Efficient User-Driven Replication

Karl Aberer, Rammohan Narendula, Athanasios Papaioannou

Unprecedented growth of online social networks (OSNs) increasingly makes privacy advocates and government agencies worrisome alike. In this paper, we propose My3, a privacy-friendly decentralized alternative for online social networking. The My3 system exp ...

Assessment of Total Transfer Capability for simultaneous transactions in decentralized multi-areas power systems

With the liberalization of the electricity market, the cross-boarder transactions have become more common but set up new problems due to the non-existence of a global interconnected network operator which would have a whole knowledge of such electrical sys ...

Subspace properties of network coding and their applications

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani

Systems that employ network coding for content distribution convey to the receivers linear combinations of the source packets. If we assume randomized network coding, during this process the network nodes collect random subspaces of the space spanned by th ...

Modeling and Measuring Performance of Data Dissemination in Opportunistic Networks

Nikodin Ristanovic

In this thesis we focus on understanding, measuring and describing the performance of Opportunistic Networks (ONs) and their applications. An “opportunistic network” is a term introduced to describe a sparse, wireless, ad hoc network with highly mobile nod ...

Non-coherent Network Coding: An Arbitrarily Varying Channel Approach

Mahdi Jafari Siavoshani

In this paper, we propose an “arbitrarily varying channel” (AVC) approach to study the capacity of non-coherent transmission in a network that employs randomized linear network coding. The network operation is modeled by a matrix channel over a ﬁnite ﬁeld ...

Performance of diffusion adaptation for collaborative optimization

Ali H. Sayed

We derive an adaptive diffusion mechanism to optimize global cost functions in a distributed manner over a network of nodes. The cost function is assumed to consist of the sum of individual components, and diffusion adaptation is used to enable the nodes t ...
