Performance Limits of Time Synchronization in Wireless Sensor Networks
—We propose a new approach to evaluate the ultimate performance limit of time synchronization in wireless sensor networks based on the estimation theory. In particular the lower ...

Spread-based heuristic for sensor selection in sensor networks
In this paper we propose a method for selecting an appropriate subset of sensors with a view to minimize estimation error while tracking a target with sensors spread across in a 2...

Initializing Sensor Networks of Non-uniform Density in the Weak Sensor Model
Abstract. Assumptions about node density in the Sensor Networks literature are frequently too strong or too weak. Neither absolutely arbitrary nor uniform deployment seem feasible ...
