PL Procesy zachodzące w sieciach bezprzewodowych charakteryzują się dużą dynamiką zmian. Z tej perspektywy, przyjęcie tradycyjnego modelu ich opisu bazującego na redukcjonistycznym paradygmacie systemów prostych jest dużym uproszczeniem. Dlatego też, w pracy postaramy się przybliżyć sieci WLAN w ujęciu[...]
EN Processes occurring in wireless networks are characterized by dynamic changes. From this perspective, the adoption of the traditional model their description based on a reductionist paradigm of simple systems is a major simplification. Therefore, the WLAN networks in the context of complex systems w[...]
