The paper addresses object localization via a distributed sensor network. A centralized estimation approach is undertaken along with a selective node activation strategy to ensure...
Abstract. Sensor relocation protocols can be employed as fault tolerance approach to offset the coverage loss caused by node failures. We introduce a novel localized structure, in...
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...
Underwater Sensor Networks (UWSN) are widely used in many applications, such as oceanic resource exploration, pollution monitoring, tsunami warnings and mine reconnaissance. In UW...
Top-k queries are a popular type of query in Wireless Sensor Networks. Typical solutions rely on coordinated root-tonodes and nodes-to-root messages and on maintaining filters at...
