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 ...

Optimal wavelength allocation and flow assignment for optical networks for profit maximization
Kabranov, O.; Makrakis, D.; Charalambous, Charalambos D.; Ionescu, D.; Von Bochmann, G. (Institute of Electrical and Electronics Engineers Inc., 2001)Automated switched optical networks (ASON) are based on control strategies that determine the optimal distribution of flows over different wavelengths, increase the profit, by allowing service providers to define and deploy ...

Optimal wavelength allocation and flow assignment in multiwavelength optical networks
Kabranov, O.; Makrakis, D.; Charalambous, Charalambos D.; Ionescu, D. (2001)Automatically Switched Optical Networks (ASON) require a control strategy that determines the optimal distribution of flows over different wavelengths. Such strategy will increase the profit, by allowing service providers ...

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 ...

Statistical analysis of multipath fading channels using shot-noise analysis: An introduction
Charalambous, Charalambos D.; Menemenlis, N.; Kabranov, O. H.; Makrakis, D. (2001)In this paper, we introduce, the use of the shot-noise analysis, brought forward by Rice, as a natural tool in computing the various statistical properties of the multipath fading channels, in wireless communications. By ...

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 ...
