— Distributed time synchronization is an important part of a sensor network where sensing and actuation must be coordinated across multiple nodes. Several time synchronization pr...
In wireless sensor networks energy is a valuable but not necessary scarce resource. While it is often assumed that nodes in sensor networks are powered by batteries, other energy s...
In this paper, we design and evaluate an energy efficient data retrieval architecture for continuous aggregate queries in wireless sensor networks. We show how the modification of...
Recently, mobile agents have been proposed for efficient data dissemination in sensor networks [1-6]. In the traditional client/server-based computing architecture, data at multip...
This paper demonstrates an energy efficient query processing technique for wireless sensor networks which achieves energy efficiency through centralized caching and variable freque...
