Ethernet passive optical networks (EPONs) have emerged as the one of the most promising candidates for next-generation access networks. These new architectures couple low-cost optics with advanced edge electronics to offer vastly improved scalability over competing digital subscriber line and cable modem offerings. This paper proposes several novel(More)
An efficient resource allocation is a fundamental requirement in high performance computing (HPC) systems. Many projects are dedicated to large-scale distributed computing systems that have designed and developed resource allocation mechanisms with a variety of architectures and services. In our study, through analysis, a comprehensive survey for describing(More)
Quality-of-service (QoS) support in Ethernet passive optical networks (EPON) is a crucial concern. However, most studies have only focused on optical line terminal (OLT) capacity allocation amongst multiple optical network units (ONU), and the further issue of intra-ONU allocation remains open. In this work a novel decentralized intra-ONU solution is(More)
Two major constraints demand more consideration for energy efficiency in cluster computing: (a) operational costs, and (b) system reliability. Increasing energy efficiency in cluster systems will reduce energy consumption, excess heat, lower operational costs, and improve system reliability. Based on the energy-power relationship, and the fact that energy(More)
0163-6804/99/$10.00 © 1999 IEEE ecently, the interest in broadband satellite networks has grown rapidly. Advances in transmission technology have led to the availability of low-cost earth terminals with interfaces to standard terrestrial networks. The relative ease of deployment and superior remote access capabilities of satellite networks are envisioned to(More)
With the increase of wireless bandwidth, wireless video applications become more and more popular. A high speed core network is needed for large-scale applications to collect video from wireless terminals in a distributed way. It is necessary to guarantee video transmission in wireless networks because video data should be firstly transmitted via wireless(More)
One of the most important objectives of a wireless network is to facilitate a prediction of users mobility regardless of their point of attachment to the network. In indoor environments the effective users motion prediction system and wireless localization technology play an important role in all aspects of peoples daily lives. In this paper we propose an(More)
