Advance reservations (ARs) were introduced for application-level dynamic scheduling of resources in a Grid infrastructure. Advance reservations of resources for a specific time in future not only ensure that all resources would be simultaneously available at the execution time of the application but also ensure that the QoS constraints of the Grid applications would be met. Previous research sh...

Dynamic aggregate bandwidth over-reservation is a scalable approach for Quality of Service (QoS) control mechanisms, since surplus of reservation allows for admitting several flows without signaling the network. Our recent work, the Advanced Class-based resource Over-Reservation (ACOR), shows interesting results by significantly reducing QoS control signaling overhead with increased resource ut...

In mobile ad hoc networks (MANETs), inefficient resource allocation causes heavy losses to the service providers and results in inadequate user proficiency. For improving and automating the quality of service of MANETs, efficient resource allocation techniques are required. In this paper, we propose an agent based bandwidth reservation technique for MANET. The mobile agent from the source start...

In the paper, author analyzes subject matter of contract for provision services to maintain reserve heat capacity. The notes that capacity is almost only in field supply, definition which not legislation. At same time, this problem covered legal literature. To disclose under study, refers such categories as «power», «heat capacity», «reservation (booking)", «reserve capacity». paper presents pr...

We propose and analyze a class of admission control algorithms based on reward optimization for multimediaservers designed to provide on-demand services to clients in an environment where workload characteristics of clients can change dynamically. These admission control algorithms are developed based on two strategic choices, namely, \deterministic" or \best-eeort" regarding quality of service...

In a basic communication system, the data’s are modulated onto a single carrier frequency. The available bandwidth is then totally occupied by each symbol. This kind of system can lead to InterSymbol-Interference (ISI) in case of frequency selective fading. The basic idea of Orthogonal Frequency Division Multiplexing (OFDM) is to divide the available spectrum into several orthogonal sub channel...

Much work has been done on establishing resource reservations over the Internet 3, 2, 8], but almost all of this work has consisted of establishing a reservation that begins immediately and has indeenite duration. An important issue is how to request an advance reservation, a reservation made now for resources that are to be reserved in the future. In this paper, we propose an architecture for ...

The present paper deals with an optimal stopping problem with several possible search areas in which travel costs are assumed among the areas. In terms of the future availability of an offer once obtained and passed up, the following two cases are considered: (1) it becomes instant.ly and forever unavailable and (2) it remains forever available, called a no recall model and a recall model. resp...
