A typical wireless sensor node has little protection against radio jamming. The situation becomes worse if energy-efficient jamming can be achieved b...

Location information is useful both for network organization and for sensor data integrity. In this article, we study the anchor-free 2D localization...

One of the useful approaches to exploit redundancy in a sensor network is to keep active only a small subset of sensors that are sufficient to cover...

Energy efficiency is a fundamental issue for outdoor sensor network systems. This article presents the design and implementation of multidimensional...

Environment monitoring in coal mines is an important application of wireless sensor networks (WSNs) that has commercial potential. We discuss the des...
