An important challenge confronted in distributed systems is the adoption of suitable and efficient algorithms for coordinator election. The main role of an elected coordinator is to manage the use of a shared resource in an optimal manner. Among all the algorithms reported in the literature, the Bully and Ring algorithms have gained more popularity. In this(More)
—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)
Optical burst switching (OBS) appears to be the best available solution to the ever-increasing demand for Internet bandwidth. As a multifaceted paradigm, it has opened up various motivating challenges in optical networking. Several analytical models regarding optical networking have been proposed in the literature. However, to the best of our knowledge,(More)
With the successful deployment of IEEE 802.11a/b/g wireless local area networks (WLANs) and the pent-up market demand for high speed wireless access, the IEEE 802.11n protocol has emerged as a promising standard with major enhancements. In order to scale to the high physical layer transmission rate of up to 600 Mbps, the current medium access control (MAC)(More)
With increase in time-critical applications over the Internet, the need for differentiating services has become a major endeavor in research communities. One promising paradigm proposed to support such traffic diversity in the next-generation Internet is Optical Burst Switching (OBS). In the literature, two simple but efficient approaches namely, threshold(More)
With increase in concern for reliability in the current and next generation of multiprocessors system-on-chip (MP-SoCs), multi-computers, cluster computers, and peer-to-peer communication networks, fault-tolerance has become an integral part of these systems. One of the fundamental issues regarding fault-tolerance is how to efficiently route a faulty(More)
Quality of service (QoS) differentiation within the optical infrastructure is under constant development due to the direct impact of the ever-rising demand for time-critical and multimedia applications in the Internet. In this paper, we propose an efficient prioritized hybrid model based on two eminent approaches namely, resource-reservation and extra(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)
