Distributed adaptive estimation of correlated node-specific signals in a fully connected sensor network
We introduce a distributed adaptive estimation algorithm operating in an ideal fully connected sensor network. The algorithm estimates node-specific signals at each node based on...

Increasing Sensor Network Lifetime by Identifying and Leveraging Nodes with Excess Energy In Heterogeneous Networks
We propose and evaluate wireless sensor routing algorithms designed to extend the lifetime of a heterogeneous wireless sensor network. The network is heterogeneous in the sensorsā...

Efficient Even Distribution of Power Consumption in Wireless Sensor Networks
One of the limitations of wireless sensor nodes is their inherent limited energy resource. Besides maximizing the lifetime of the sensor node, it is preferable to distribute the e...

Optimized query routing trees for wireless sensor networks
In order to process continuous queries over Wireless Sensor Networks (WSNs), sensors are typically organized in a Query Routing Tree (denoted as T) that provides each sensor with ...

On the Limitations of Random Sensor Placement for Distributed Signal Detection
— We consider the design of a sensor network for detecting an emitter who if present is known to be located in an interval but whose exact position is unknown. We seek to minimiz...
