In Wireless Sensor Networks (WSNs), address-based routing approaches often lead to severe problems due to node mobility, energy-saving sleep-cycles, and often missing or unreliabl...
Introducing mobile data sinks into wireless sensor networks (WSNs) improves the energy efficiency and the network lifetime, and is demanded for many application scenarios, such a...
: Power Conservation is one of the most important challenges in wireless sensor networks. In this paper, we present two minimum-energy routing algorithms. Our main goal is to reduc...
This paper presents a data routing protocol for a non-mobile, locationaware wireless sensor network that is primarily designed for continuous monitoring application (e.g. environm...
—We study the problem of in-network processing and queries of trajectories of moving targets in a sensor network. The main idea is to exploit the spatial coherence of target traj...
