Sensorium - An Active Monitoring System for Neighborhood Relations in Wireless Sensor Networks
Communication neighborhood in wireless sensor networks changes often as links break or appear. Therefore, monitoring link quality and (logical) network topology is necessary. As no...

Hierarchical routing over dynamic wireless networks
Dynamic networks are those where the topology changes over time and therefore efficient routes need to be maintained by frequent updates. Such updates could be costly in terms of ...

Greedy Hop Distance Routing Using Tree Recovery on Wireless Ad Hoc and Sensor Networks
—Connectivity-based routing protocols use the hop count vector to a group of anchors for packet forwarding. Due to the discrete nature of hop count based coordinates, without an ...

Distributed Direction-Based Localization in Wireless Sensor Networks
Location awareness is an attractive research issue in the wireless sensor network (WSN). However, precise location information may be unavailable due to the constraint in energy, ...

Analyzing Connectivity-Based Multi-Hop Ad-hoc Positioning
We investigate the theoretical limits of positioning algorithms. In particular, we study scenarios where the nodes do not receive anchors directly (multi-hop) and where no physica...
