—Multicasting is emerging as an enabling technology for multimedia transmissions over wireless networks to support several groups of users with flexible quality of service (QoS) requirements. Although multicast has huge potential to push the limits of next generation communication systems; it is however one of the most challenging issues currently being(More)
Generic generalized minimum variance-based (GMV) controllers have been adopted as efficient control mechanisms especially in presence of measurement noise. However, such controllers exhibit degraded performance with change in process dynamics. To overcome this problem, a novel congestion controller based on active queue management (AQM) strategy for(More)
—Knowledge on the dynamics of standard epidemic models and their variants over complex networks has been well-established primarily in the stationary regime, with relatively little light shed on their transient behavior. In this paper, we analyze the transient characteristics of the classical susceptible-infected (SI) process with a recovery policy modeled(More)
—Opportunistic spectrum access (OSA) is a promising reform paradigm envisioned to address the issue of spectrum scarcity in cognitive radio networks (CRNs). While current models consider various aspects of the OSA scheme, the impact of retrial phenomenon in multi-channel CRNs has not yet been analyzed. In this work, we present a continuous-time Markov chain(More)
—Fluctuations in electricity tariffs induced by the sporadic nature of demand loads on power grids has initiated immense efforts to find optimal scheduling solutions for charging and discharging plug-in electric vehicles (PEVs) subject to different objective sets. In this paper, we consider vehicle-to-grid (V2G) scheduling at a geographically large scale in(More)
We investigate the stationary characteristics of an M/G/1 retrial queue where the server, subject to active failures, primarily attends incoming calls and directs outgoing calls only when idle. On finding the server unavailable (busy or failed), inbound calls join the orbit and reattempt for service at exponentially-distributed time intervals. The system(More)
Optical Burst Switching (OBS) has been widely admitted as a viable candidate for the evolving all-optical network control framework of nowadays Internet core to meet the explosive demand of bandwidth constraints in mul-timedia and real-time applications. A number of analytical models have been proposed to characterize the behavior of OBS networks. These(More)
