Client/server information systems use caching techniques to reduce the volume of transmitted data as well as response time and, especially in the case of systems with mobile clien...
One way to prolong the lifetime of a wireless sensor network is to schedule the active times of sensor nodes, so that a node is active only when it is really needed. In the dynami...
Mobile ad-hoc networks (MANETs) are infrastructure-less networks where no central network management exists, composed of mobile nodes over wireless links. Network topology in MANE...
—We propose a new multi-hop routing protocol for wireless sensor networks, suited for monitoring and control applications. The aim of this research is to adapt flat and hierarch...
Location monitoring systems are used to detect human activities and provide monitoring services, e.g., aggregate queries. In this paper, we consider an aggregate location monitori...
