Network Correlated Data Gathering with Explicit Communication: NP-Completeness and Algorithms

Martin Vetterli, Razvan Cristescu

We consider the problem of correlated data gathering by a network with a sink node and a tree based communication structure, where the goal is to minimize the total trans- mission cost of transporting the information collected by the nodes, to the sink nod ...

Power-Efficient Sensor Placement and Transmission Structure for Data Gathering under Distortion Constraints

Razvan Cristescu

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 data can be reconstructed at a sink within specified distortion bounds whi ...

Lossy Network Correlated Data Gathering with High-Resolution Coding

Razvan Cristescu

Sensor networks measuring correlated data are considered, where the task is to gather data from the network nodes to a sink. A specific scenario is addressed, where data at nodes are lossy coded with high-resolution, and the information measured by the nod ...
