Signal Processing Challenges in Distributed Stream Processing Systems

Distributed stream processing represents a novel computing paradigm where data, sensed externally and possibly preprocessed, is pushed asynchronously to various connected computing devices with heterogeneous capabilities for processing. It enables novel ap ...

MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Matthias Grossglauser, Jun Luo, Jacques Panchard

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

Sensing reality and communicating bits: A dangerous liaison

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The successful design of sensor network architectures depends crucially on the structure of the sampling, observation, and communication processes. One of the most fundamental questions concerns the sufficiency of discrete approximations in time, space, an ...

Secure Data Communication in Mobile Ad Hoc Networks

Panagiotis Papadimitratos

We address the problem of secure and fault-tolerant communication in the presence of adversaries across a multihop wireless network with frequently changing topology. To effectively cope with arbitrary malicious disruption of data transmissions, we propose ...

The Global Sensor Networks middleware for efficient and flexible deployment and interconnection of sensor networks

Karl Aberer, Manfred Hauswirth, Ali Salehi

The lack of standardization and the continuous inflow of novel sensor network technologies have made their deployment the main factor of manpower consumption, considerably complicate the interconnection of heterogeneous sensor networks, and make portable a ...

Efficient Distributed Multiresolution Processing for Data Gathering in Sensor Networks

Razvan Cristescu, Jugoslava Acimovic

We consider large sensor networks where the cost of collecting data from the network nodes to the data gathering sink is critical.~We propose several algorithms that use limited local communication and distributed signal processing to make communication mo ...

Adaptive Distributed Algorithms for Power-Efficient Data Gathering in Sensor Networks

Razvan Cristescu, Jugoslava Acimovic

In this work, we consider the problem of designing adaptive distributed processing algorithms in large sensor networks that are efficient in terms of minimizing the total power spent for gathering the spatially correlated data from the sensor nodes to a si ...

On the optimal density for real-time data gathering of spatio-temporal processes in sensor networks

Martin Vetterli, Razvan Cristescu

We consider sensor networks that measure spatio-temporal correlated processes. An important task in such settings is the reconstruction at a certain node, called the sink, of the data at all points of the field. We consider scenarios where data is time cri ...

Scaling Laws for Correlated Data Gathering

Martin Vetterli, Razvan Cristescu

Consider a set of correlated sources located at the nodes of a network, and a sink to which the data from all the sources has to arrive. We address the minimization of a separable joint communication cost function given by the product [rate]
