| dc.description.abstract | This thesis deals with the processing of the RSSI parameter representing the received signal strength of IEEE 802.15.4 standard in the 2.4 GHz ISM band. Signal samples are processed with approximation methods. On a basis of a signal strength of received frames a distance between two sensor nodes using the log-normal shadowing radio propagation model (LNSM) is estimated. The work also deals with the experimental implementation of the algorithm for dynamic calibration of coefficients necessary to calculate the estiamted distance. There is made the design, processing and verification of this system in practice. | cs |
| dc.description.abstract | Práca sa zaoberá spracovaním parametru RSSI reprezentujúceho veľkosť prijímanej výkonovej úrovne rádiového signálu štandardu IEEE 802.15.4 v ISM pásme 2,4GHz. Vzorky signálu sú spracované pomocou aproximačných metód. Na základe RSSI sa ďalej odhaduje vzdialenosť pomocou logaritmického útlmového modelu prostredia (LNSM). Práca sa zaoberá experimentálnym algoritmom pre implementovanie dynamickej kalibrácie jednotlivých koefcientov nutných pre výpočet samotnej vzdialenosti. Je prevedený návrh, spracovanie a overenie tohoto systému v praxi. | sk |
