Centralized boundary discovery algorithms for anchor-free localization in wireless sensor networks

A study of localization techniques in the wireless sensor network are a subject of the many research team in the world. Most of the solutions propose the optimization in term of the accuracy of the coordinate´s assignment improvement. However, the other very important metric considering the energy cost of the localization process also exists, but nowadays there is a lack of this work regarding to the study of localization in the energy consumption terms. This paper deals with the investigation of the anchor-free localization technique AFL and introduces the results from the simulations, where the energy cost of the several initial localization processes was investigated. We have focused on the work, with the centralized boundary discovery CBD algorithm to study its portion on the entire energy consumption.
