AVS video decoder on multicore systems: Optimizations and tradeoffs
(2011)Newer video compression standards provide high video quality and greater compression efficiency, compared to their predecessors. Their increased complexity can be outbalanced by leveraging all the levels of available ... -
A converged network architecture for energy efficient mobile cloud computing
(2014)Mobile computation offloading has been identified as a key enabling technology to overcome the inherent processing power and storage constraints of mobile end devices. To satisfy the low-latency requirements of content-rich ... -
Dishonest reporting in queue-based cross-layer network optimization
(2012)Queue-based cross-layer optimization algorithms have recently been a subject of intensive research in wireless networks. Their purpose is to guarantee stable operation and to achieve some form of fairness among users, ... -
An efficient power constrained transmission scheme for hybrid OW/RF systems
(2014)This paper investigates link layer transmission schemes for hybrid optical wireless (OW)/radio frequency (RF) systems with constraints on both per-link and total power consumption at the transmitter. Assuming timeslot ... -
A fair scheduling policy for wireless channels with intermittent connectivity
(2008)We consider a system of parallel queues with the constraint that only one queue can be served at a time. Each queue can be served through a wireless channel with intermittent connectivity. We propose a policy which serves ... -
Network coding and service reneging for real-time communication in sensor networks
(2010)In a number of application domains, the volatility of the environment where Wireless Sensor Networks (WSNs) should operate engenders time constraints on the generation, processing, and communication of sensory data. In ... -
On optimal routing in overloaded parallel queues
(2013)We consider the problem of routing Bernoulli arrivals to parallel queues, where each queue provides service according to an independent Bernoulli process. We assume that the total arrival rate exceeds the sum of the service ... -
Optical wireless network convergence in support of energy-efficient mobile cloud services
(2015)Mobile computation offloading has been identified as a key-enabling technology to overcome the inherent processing power and storage constraints of mobile end devices. To satisfy the low-latency requirements of content-rich ... -
Optimal server assignment in a two-stage tandem queueing system
(2020)We study Markovian queueing systems consisting of two stations in tandem. There is a dedicated server in each station and an additional server that can be assigned to any station. Assuming that linear holding costs are ... -
Queue and channel state awareness for maximum throughput access control in CSMA/CA-based wireless LANs
(2009)This paper introduces two important enhancements to the IEEE 802.11 medium access control (MAC) protocols which are not considered in the current IEEE 802.11 MAC protocol: the channel state between the transmitter and the ... -
Queueing model and optimization of packet dropping in real-time wireless sensor networks
(2012)We consider the problem of modeling the transmission of real-time data from a single node of a wireless sensor network to the next hop or access point. Generated packets are placed in a single position buffer and are ... -
Stochastic optimization of electric vehicle charging stations
(2019)With range anxiety becoming the every day problem for Battery Electric Vehicles (BEVs) owners, even more research is being conducted in the field of BEV charging and Charging Stations (CSs) scheduling optimization. In this ... -
Virtual 802.11 wireless networks with guaranteed throughout sharing
(2016)In this work, we present how programmable data-plane technology (software routers) offers an easy-To-Apply mechanism to create virtual wireless networks and support buffering and scheduling decisions. Furthermore, we present ... -
Wireless and wired network convergence in support of Cloud and mobile Cloud services: The CONTENT approach
(2014)The project CONTENT proposes a next generation ubiquitous converged infrastructure to support Cloud and mobile Cloud computing services. The proposed infrastructure facilitates interconnection of fixed and mobile end users ...
