One of the most challenging tasks in a disaster scenario is the detection and localization of
victims with high accuracy and minimum delay, especially in out-of-coverage areas. In the …

In this paper, the reduction of RSSI (received signal strength indicator) variation for indoor
position estimation in wireless sensor networks (WSNs) is studied through simulation. We …

In this thesis, location determination algorithms for cellular mobile radio systems employing
orthogonal frequency division multiplexing (OFDM) are investigated. For location estimation …

The vivid success of the emerging wireless sensor technology (WSN) gave rise to the notion
of localization in the communications field. Indeed, the interest in localization grew further …

In this paper, we propose a geometric positioning method for hybrid wireless networks,
based on a set membership method. Three common types of radio observables are …

During large-scale disasters, emergency communication systems that are reliable,
responsive, and energy-efficient are crucial. This thesis focuses on designing reliable …
