Cache consistency in Wireless Multimedia Sensor Networks

Dimokas, N.; Katsaros, D.; Manolopoulos, Y. (2010)

The production of cheap CMOS cameras, which are able to capture rich multimedia content, combined with the creation of low-power circuits, gave birth to what is called Wireless Multimedia Sensor Networks (WMSNs). WMSNs ...

Edge betweenness centrality: A novel algorithm for QoS-based topology control over wireless sensor networks

Cuzzocrea, A.; Papadimitriou, A.; Katsaros, D.; Manolopoulos, Y. (2012)

In this paper we propose a novel topology-control algorithm, called edge betweenness centrality (EBC). EBC is based on the concept of betweenness centrality, which has been first introduced in the context of social network ...

High performance, low complexity cooperative caching for wireless sensor networks

Dimokas, N.; Katsaros, D.; Tassiulas, L.; Manolopoulos, Y. (2011)

During the last decade, Wireless Sensor Networks have emerged and matured at such point that they currently support several applications such as environment control, intelligent buildings, target tracking in battlefields. ...

Node Isolation Probability for Serial Ultraviolet UV-C Multi-hop Networks

Vavoulas, A.; Sandalidis, H. G.; Varoutas, D. (2011)

Non-line-of-sight optical wireless transmission, operated in the unlicensed ultraviolet UV-C band, has been recently suggested as an alternative means of communication. However, due to limited coverage, relayed UV-C networks ...
