A snapshot of my scientific career

During her five years scientific career, Iva Bojic had different research interests, including self- organization, energy efficiency, and management in machine-to-machine systems. For her master thesis she proposed a distributed self-organized energy- efficient model of service provisioning process for mobile network users who share a common interest in a service content offered in the network. The model was based on an idea that such users could individually acquire disjunctive parts of service content from a remote server (via a wide area mobile network), and then subsequently exchange them among themselves in an ad hoc local network in a peer-to-peer fashion, thus allowing each user to reassemble the entire content for her/his own use. Within the M2M Communication Challenges project supported by the Ericsson Nikola Tesla, where Iva Bojic is a principal investigator, she dealt with management in machine-to-machine systems. She is familiar with the current efforts in the area of M2M identification and addressing standardization and worked on a new identification scheme that would allow M2M Devices to establish communication with M2M Server or other M2M Devices in all available scenarios defined in the current ETSI standards (i.e. with or without intermediary devices). Finally, for her PhD thesis she investigated a biologically inspired model of self- synchronization and proposed its modification in order to be applicable in machine-to-machine systems. She implemented the Mirollo and Strogatz model in a real-world environment using Libelium Waspmote sensors and concluded that time synchronization cannot be achieved. She thus extended their model with a mechanism for dynamic frequency adaptation and showed that time synchronization can be achieved with a precision of 69 ms.
