Extended Navigability of Small World Networks: Exact Results and New Insights

Paolo De Los Rios, Cécile Caretta Cartozo

Navigability of networks, that is, the ability to find any given destination vertex starting from any other vertex, is crucial to their usefulness. In 2000 Kleinberg showed that optimal navigability could be achieved in small world networks provided that a ...

Delay with network coding and feedback

Christina Fragouli, Lorenzo Keller

We consider the problem of minimizing delay when broadcasting over erasure channels with feedback. A sender wishes to communicate the same set of mu messages to several receivers over separate erasure channels. The sender can broadcast a single message or ...

Delay with network coding and feedback

Christina Fragouli, Lorenzo Keller

We consider the problem of minimizing delay when broadcasting over erasure channels with feedback. A sender wishes to communicate the same set of μ messages to several receivers over separate erasure channels. The sender can broad- cast a single message or ...

Transactors: Unifying Transactions and Actors

Rachid Guerraoui, Martin Odersky, Mohsen Lesani

Composability and deadlock-freedom are important properties that are stated for transactional memory (TM). Commonly, the Semantics of TM requires linearization of transactions. It turns out that linearization of transactions that have cyclic communication ...

Chasing the Weakest System Model for Implementing Omega and Consensus

Martin Hutle

Aguilera et al. and Malkhi et al. presented two system models, which are weaker than all previously proposed models where the eventual leader election oracle Omega can be implemented, and thus, consensus can also be solved. The former model assumes unicast ...

Optimal Multiband Joint Detection for Spectrum Sensing in Cognitive Radio Networks

Ali H. Sayed

Spectrum sensing is an essential functionality that enables cognitive radios to detect spectral holes and to opportunistically use under-utilized frequency bands without causing harmful interference to legacy (primary) networks. In this paper, a novel wide ...

Multiline Addressing by Network Flow

Friedrich Eisenbrand

We consider an optimization problem arising in the design of controllers for OLED displays. Our objective is to minimize amplitude of the electrical current through the diodes which has a direct impact on the lifetime of such a display. Modeling the proble ...

Latency-aware Leader Election

André Schiper, Martin Hutle, Nuno Filipe de Sousa Santos

Experimental studies have shown that electing a leader based on measurements of the underlying communication network can be beneficial. We use this approach to study the problem of electing a leader that is eventually not only correct (as aptured by the fa ...

Latency-aware leader election

André Schiper, Martin Hutle, Nuno Filipe de Sousa Santos

Experimental studies have shown that electing a leader based on measurements of the underlying communication network can be beneficial. We use this approach to study the prob- lem of electing a leader that is eventually not only correct (as captured by the ...

Optimal Algorithms for Page Migration in Dynamic Networks

We present an extension of a classical data management subproblem, the page migration. The problem is investigated in dynamic networks, where costs of communication between different nodes may change with time. We construct asymptotically optimal online al ...
