Wireless technologies

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

•As PC became more common, it became obvious one would need to share data and peripherals between them efficiently.Floppy discs could not be the solution. Hence the idea of a network.•The necessities to have one database that many users can access simultaneously made networking very relevant.•Great demand to share devices ( e.g. printer sharing in companies).
