Data broadcasting in ad-hoc networks of pervasive devices: Modeling and simulations
Wang, L.; Charalambous, Charalambos D.; Makrakis, D.; Vlajic, N. (2003)With the rapid growth of wireless networks and demand for services, wireless data broadcast has become a fundamental communication mechanism to enhance the services in ad hoc network of pervasive devices. This work focuses ...

Near optimal wireless data broadcasting based on an unsupervised neural network learning algorithm
Vlajic, N.; Makrakis, D.; Charalambous, Charalambos D. (2001)Wireless Data Broadcasting (WDB) is proven to be an efficient information delivery mechanism of nearly unlimited scalability. However, successful performance of a WDB based system is not always guaranteed - it strongly ...

Performance aspects of data broadcast in wireless networks with user retrials
Vlajic, N.; Charalambous, Charalambos D.; Makrakis, D. (2004)The User retrial phenomenon and its significant impact on network performance in unicast wireless systems are known and relatively well studied in the literature. However, there have been no previous studies on the impact ...

TDM- vs. FDM- based data-item scheduling in wireless broadcast systems with user retrials
Vlajic, N.; Charalambous, Charalambos D.; Makrakis, D. (2003)In the previous research works on wireless data broadcast, time-division-multiplex (TDM) based data-item scheduling has been exclusively studied, while no mention or clear evidence against frequency-division-multiplex, ...

Wireless broadcast data scheduling in environment with re-attempt users: Optimization through intelligent feedback monitoring
Vlajic, N.; Charalambous, Charalambos D.; Makrakis, D. (2001)Most of the previous work on wireless broadcast data scheduling has been based on simplified assumptions regarding mobile user behaviour. In this paper, we show that the employment of a realistic mobile user behaviour model ...

Wireless data broadcast in systems of hierarchical cellular organization
Vlajic, N.; Charalambous, Charalambos D.; Makrakis, D. (2003)In recent years, both wireless data broadcast (WDB) and hierarchical cell structure (HCS) have attracted the attention of the scientific community, yet they have been treated as entirely separate research topics. This paper ...
