We consider the problem of correlated data gathering in sensor networks with multiple sink
nodes. The problem has two objectives. First, we would like to find a rate allocation on the …

By deploying hundreds or thousands of microsensors and organizing a network of them, one
can monitor and obtain information of environments or objects for use by users, applications …

We consider the problem of correlated data gathering by a network with a sink node and a
tree communication structure, where the goal is to minimize the total transmission cost of …

In many energy-constrained wireless sensor networks, nodes cooperatively forward
correlated sensed data to data sinks. In order to reduce the communication cost (eg overall …

In this article, we design techniques that exploit data correlations in sensor data to minimize
communication costs (and hence, energy costs) incurred during data gathering in a sensor …

We consider the joint optimization of sensor placement and transmission structure for data
gathering, where a given number of nodes need to be placed in a field such that the sensed …

We propose in this paper a novel scheme for correlated data gathering in energy-and
bandwidth-limited wireless sensor networks based on Distributed Source Coding (DSC). We …

Consider a set of correlated sources located at the nodes of a network, and a set of sinks
that are the destinations for some of the sources. The minimization of cost functions which …

In this paper, we consider energy-efficient gathering of correlated data in sensor networks.
We focus on single-input coding strategies in order to aggregate correlated data. For foreign …

A network of sensors can be used to obtain state-based data from the area in which they are
deployed. To reduce costs, the data, sent via intermediate sensors to a sink, are often …
