Abstract
In this paper, we investigate the accuracy of the
received signal strentgh indicator (RSS) based
2D localization in indoor environments. A large
volume of measurements are obtained from our
MicaII testbed and the analysis results are
presented. The tests are carrried out in three
steps; First, RSS measurements are obtained for
various distances and a proper channel model is
determined. Second, distances to beacon nodes
are estimated for various antenna orientations
and the optimum anntenna position for the
experimental setup is determined. In the last step,
best antenna orientation is used to estimate the
position of the blindfolded node by Trilateration
method. Our results in two different scenairos have shown that we attain more than 90%
accuracy at the optimum antenna position.

Telsiz Duyarga Ağlarında Sinyal Gücü Belirteci ile 2-Boyutlu İç Ortam Konum Tahmini Üzerine Deneysel Bir Çalışma
Abstract
Bu çalışmada telsiz duyarga ağlarında sinyal gücü belirteci ile konum tahmini başarımı incelenmiş ve Crossbow MicaII duyargaları ile iç ortam deneylerinden elde edilen sonuçlar sunulmuştur. Öncelikle, çeşitli uzaklıklarda sinyal gücü değerleri toplanmış ve kanal modeli belirlenmiştir. İkinci aşamada anten yönünün mesafe kestirimi başarısına etkisini belirlemek amacıyla çeşitli pozisyonlarda sinyal gücü ölçümleri alınmış ve parıldak (beacon) duyargalara mesafe kestirimleri yapılmıştır. Son olarak, belirlenen en iyi anten pozisyonu için 2-boyutlu üçgenleme (trilateration) yöntemi ile kör (blindfolded) duyarga pozisyonu tahmin edilmiştir. İki farklı senaryo üzerinde yapılan ölçüm sonuçları 90% üzerinde başarım elde edildiğini göstermektedir.

The acceptance process of the articles sent to the journal consists of the following stages:
1. Each submitted article is sent to at least two referees at the first stage.
2. Referee appointments are made by the journal editors. There are approximately 200 referees in the referee pool of the journal and these referees are classified according to their areas of interest. Each referee is sent an article on the subject he is interested in. The selection of the arbitrator is done in a way that does not cause any conflict of interest.
3. In the articles sent to the referees, the names of the authors are closed.
4. Referees are explained how to evaluate an article and are asked to fill in the evaluation form shown below.
5. The articles in which two referees give positive opinion are subjected to similarity review by the editors. The similarity in the articles is expected to be less than 25%.
6. A paper that has passed all stages is reviewed by the editor in terms of language and presentation, and necessary corrections and improvements are made. If necessary, the authors are notified of the situation.
