    • Optimal jammer placement in wireless localization systems 

      Gezici, Sinan; Bayram, S.; Kurt, M. N.; Gholami, M. R. (Institute of Electrical and Electronics Engineers Inc., 2016)
      In this study, the optimal jammer placement problem is proposed and analyzed for wireless localization systems. In particular, the optimal location of a jammer node is obtained by maximizing the minimum of the Cramér-Rao ...
    • Optimal jamming of wireless localization systems 

      Gezici, Sinan; Gholami, M.R.; Bayram, S.; Jansson, M. (IEEE, 2015-06)
      In this study, optimal jamming of wireless localization systems is investigated. Two optimal power allocation schemes are proposed for jammer nodes in the presence of total and peak power constraints. In the first scheme, ...
    • Optimal power allocation for jammer nodes in wireless localization systems 

      Bayram, S.; Keskin, M. F.; Gezici, Sinan; Arıkan, Orhan (Institute of Electrical and Electronics Engineers Inc., 2017)
      In this paper, optimal power allocation strategies are investigated for jammer nodes in a wireless localization system. Building upon the concept of the restricted Bayesian approach, a generalized optimization strategy, ...
    • Power allocation strategies for channel switching and wireless localization 

      Sezer, Ahmet Dündar (Bilkent University, 2018-08)
      Optimal power allocation is an important approach for enhancing performance of both communication and localization systems. In this dissertation, optimal channel switching problems are investigated for average capacity ...
    • Power control games between anchor and jammer nodes in wireless localization networks 

      Sezer, Ahmet Dündar; Gezici, Sinan (Institute of Electrical and Electronics Engineers, 2018)
      In this paper, a game theoretic framework is proposed for wireless localization networks that operate in the presence of jammer nodes. In particular, power control games between anchor and jammer nodes are designed for a ...
    • Range estimation using simple infrared sensors without prior knowledge of surface parameters 

      Yüzbaşıoğlu, Çağrı; Barshan, Billur (IEEE, 2004)
      This paper describes a new method for range estimation using low-cost infrared sensors. The intensity data obtained with infrared sensors depends highly on the surface properties and the configuration of the sensors and ...
    • A study of localization metrics: evaluation of position errors in wireless sensor networks 

      Aksu, H.; Aksoy, D.; Korpeoglu, I. (Elsevier BV, 2011)
      For wireless sensor network applications that require location information for sensor nodes, locations of nodes can be estimated by a number of localization algorithms, which inevitably may introduce various types of errors ...
