We extend the service abstraction in the Open Grid Services Architecture[12] for Quality of Service (QoS) properties. The realization of QoS often requires mechanisms such as advance or on-demand reservation of resources, varying in type and implementation, and independently controlled and monitored. Foster et al. propose the GARA [10] architecture. The(More)
Grid computing provides a global-scale distributed computing infrastructure for executing scientific and business applications. An important requirement is the need to make this infrastructure appear as a single logical coordinated resource – which in reality consists of a variety of resources aggregated across different administrative domains. The(More)
Keeping in mind the present network management research trends, it can be safely stated that in the near future enterprise networks and ISPs will need a network management entity to dynamically manage QoS networks. DiffServ is one of the emerging networks that introduces bandwidth broker as its logical resource, network and policy management module. Due to(More)

In this paper, we propose a novel approach for reducing the download time of large files over the Internet. Our approach, known as parallelized file transport protocol (P-FTP), proposes simultaneous downloads of disjoint file portions from multiple file servers. P-FTP server selects file servers for the requesting client on the basis of a variety of QoS(More)
Large range of tiny, embedded sensor devices capable of sensing, communicating and routing data are available now a days. Due to higher failure rate of sensor nodes or their mobility, the sink node might not exist in their transmission range. We proposed an approach which uses fuzzy logic to deal with diverse QoS requirements of sensor applications. In this(More)
On board IP networks are an effective mean to provide uninterrupted Internet access to public transport passengers. Such networks require optimal resource allocation due to the scarcity and high cost of network resources. The parallelized file transfer protocol (P-FTP) is a novel network resource aware parallel technique for improving file transfer(More)
The parallelized $le transfer protocol (P-FTPJ is a novel network resource aware parallel technique for improving file transfer performance on the Internet. Before starring the parallel file transfer sessions, it considers tJw available resources in the network (available bandwidih) and at the $le servers (memory and CPU utilization). n e client dynamically(More)
