We consider the recently proposed XQL language, which is designed to query XML documents by content and structure. We show that an already existing model, namely \Proximal Nodes&q...
Sensor networks are often used to perform monitoring tasks, such as animal and vehicle tracking, or the surveillance of enemy forces in military applications. In this paper we int...
Graphs are fundamental data structures and have been employed for centuries to model real-world systems and phenomena. Random walk with restart (RWR) provides a good proximity sco...
Structured peer-to-peer systems--also known as key-based routing protocols--offer a base for a broad range of applications. In the past, different topology adaptation mechanisms fo...
Abstract— This paper proposes a simple yet efficient localization algorithm for GPS-free sensor nodes in wireless sensor networks (WSN). Our approach is hybrid in the sense that...
