Performance analysis of positioning in wireless sensor networks

Devices positioning plays an important role in Wireless sensor networks (WSNs) networks. The paper deals with performance evaluation of positioning in WSNs. The performance is compared with basic DV based positioning methods and proximity based location methods. They do not belong to the most accurate methods, but on the other hand they are low cost alternative to more expensive methods. The basic methods are improved by optimized algorithms proposed in our previous papers. The objective of the paper is to perform a performance analysis of these improved methods and try to find optimal method for investigated conditions. We analyze the influence of various conditions on the accuracy of localization methods. Streszczenie. Pozycjonowanie odgrywa wazną role w bezprzewodowych sieciach czujnikow. Artykul przedstawia metode DV (distance vecor) i porownuje ją z innymi (niekiedy prostszy mi i tanszymi) metodami. W metodzie podstawowej zastosowano ulepszony algorytm. Przeanalizowano wplyw roznych warunkow pracy na dokladnośc lokalizacji. (Analiza metod pozycjonowania w bezprzewodowych sieciach czujnikow).
