- Path Planning of Mobile Landmarks for Localization in Wireless Sensor Networks
- Many applications of wireless sensor networks require the sensor nodes to obtain their locations. The main idea in most localization methods has been that some nodes with known coordinates (e.g., GPS-equipped nodes) transmit beacons with their coordinates in order to help other nodes to localize themselves. A promising method that...

- High-Throughput Multicast Routing Metrics in Wireless Mesh Networks
- The stationary nature of nodes in a mesh network has shifted the main design goal of routing protocols from maintaining connectivity between source and destination nodes to finding high-throughput paths between them. Lately, numerous link-quality based routing metrics have been proposed for choosing high-throughput paths for unicast protocols. This paper...

- Automated Rule-Based Diagnosis Through a Distributed Monitor System
- In today's world where distributed systems form many of the critical infrastructures, dependability outages are becoming increasingly common. In many situations, it is necessary to not just detect a failure, but also to diagnose the failure, i.e., to identify the source of the failure. Diagnosis is challenging since high throughput...
