Multiple frequency medium access control protocols and applicationsMultiple frequency medium access control protocols and applications Διπλωματική Εργασία 2014-03-242012enIn Wireless Sensor Networks (WSN's), nodes are scattered at dicult-to- reach areas and any interaction with a node after its initial setup is usually dicult. As such, applications designed for this kind of networks must be low power and ad-hoc in nature, as the topology of such networks is usually unknown. In this thesis we propose a new cross-layer communication proto- col adhering to the concepts of low-power, low trac, ad-hoc WSN's. The designed protocol utilizes multiple frequencies to address the link, medium access control (MAC) and routing over an ad-hoc topology, while attempting to function despite the common innate problems of such networks such as partitioning or interference. http://creativecommons.org/licenses/by/4.0/Πολυτεχνείο Κρήτης::Τμήμα Ηλεκτρονικών Μηχανικών και Μηχανικών ΥπολογιστώνAgadakos_Nikolaos_Dip_2012.pdfChania [Greece]Library of TUC2014-03-24application/pdfN/Ahttp://www.library.tuc.gr/artemis/DT2013-0191/DT2013-0191.pdffree Agadakos Nikolaos Αγαδακος Νικολαος Bletsas Aggelos Μπλετσας Αγγελος Karystinos Georgios Καρυστινος Γεωργιος Deligiannakis Antonios Δεληγιαννακης Αντωνιος Technical University of Crete Πολυτεχνείο Κρήτης ΔΙΠ3019
