Video-aware relay selection in single-carrier and OFDM wireless systems
(2014)
In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. ...
A delay based optimization scheme for peak load reduction in the smart grid
(2012)
A measurement campaign based on commodity wireless sensors shows that the majority of thermostatic loads in a user premise are described by periodic pulse waves. The superposition of these loads results to high peak power ...
Wireless networks capacity characterization and how to approach it
(2007)
Wireless systems possess attributes fairly different than those that formed the design guidelines of the Internet. Hence, novel approaches are needed for architecting networks that seamlessly integrate wired and wireless ...
Novel metrics and experimentation insights for dynamic frequency selection in wireless LANs
(2011)
The rapidly increasing popularity of IEEE 802.11 WLANs has created unprecedented levels of congestion in the unlicensed frequency bands, especially in densely populated urban areas. Performance experienced by end-users in ...
A demonstration of a relaying selection scheme for maximizing a diamond network's throughput
(2012)
We demonstrate a queue-aware algorithm studied in a diamond network topology. This algorithm's decisions are obtained from an analytical optimization framework relying on our technical work [4] and we devise an implementation ...
Distributed resource allocation mechanism for SOA service level agreements
(2011)
Enterprise computing facilities, such as data centers or server farms typically employ service-oriented architectures (SOA) to support multiple, XML-based Web Services. They are typically architected in multiple computing ...
Broadcast erasure channel with feedback-capacity and algorithms
(2009)
We consider the two-user broadcast erasure channel where feedback in the form of ack messages is fed back to the transmitter. We provide an upper bound to the capacity region of this system. We then present two algorithms ...
