Özet
Nowadays, determining the location of the users and devices in indoorbuildings is promising research topic. Accurate position determination of the usersfor indoor environments is used for numerous applications such as public safety,supermarkets, health care applications, travelling, social networks and tourism.However, global positioning systems created for outdoor localizations cannot beused for indoor positioning systems (IPS) because detecting the exact position of atarget is an issue for IPS. For indoor environments, there are several positioningalgorithms such as lateration, fingerprinting, dead reckoning etc. Lateration is lowcost and easy to deploy when compared to other existing algorithms. Therefore, inthis study, received signal strength based pure lateration that uses synthetic datagenerated from MATLAB is proposed. The performance of pure lateration isinvestigated in terms of several performance metrics such as effect of varyingnumber of the access points (AP), varying dimensions of the measurement area,varying Gaussian Noise power and varying number of test points in the field. Thesimulation of the pure lateration algorithm is conducted in MATLAB. The effect ofthe performance metrics are investigated and discussed in details. According to theresults, accuracy performance of lateration is increased when the number of APsincrease in the area, however this will bring some hardware costs. In addition, whenthe number of test points increases in the field, in other words the step size betweentwo test points decreases in the field the error performance of lateration is alsoenhanced however, this will also cause to computational costs. Finally, enlargingthe measurement area causes to decrease the accuracy performance of lateration asexpected. The main purpose of this study is to obtain the optimum conditions forlateration to provide a solution for real time applications. For future work, the realtime implementations of this study are performed and to improve the accuracyperformance, it is aimed to use a curve fitting idea to the measured values.
