Energy-on-Demand home networking is a newly proposed paradigm, by which electric power is supplied to appliances and devices, in response to explicit requests. Energy-onDemand is especially effective when multiple power sources can be used in a house. In order to utilize the power from multiple sources, it is needed to get the best matching between power sources and powered devices. We focus on...

We design and implement an optical slot switching network for bulk content transfer. To realize the slot switching network, we employ the generalized multiprotocol label switching (GMPLS) extension protocol to reserve and release slots dynamically according to the application. We use optical switches as relay points in the slot switching network, and we employ a 10 ns highspeed Pb,La Zr,Ti O3 (...

the main purpose of this article is to determine the nature and effects of reservation of title clauses in iranian law. to bring out the exact comprehension of its nature in iranian law, the study of the matter in other legal systems is required. although it is not always easy to pass upon the question of validity of these clauses in iranian law, by highlighting the security interest in such co...

In order to limit hando blocking probability, in cellular systems admission control can be applied to new call requests and resources reserved for future hando attempts. Such resource reservation strategies have been widely studied in the literature. The denial of new call attempts, however, impacts system throughput creating a trade-o with hando performance. The contribution of this paper is a...

Multimedia applications have timing requirements that cannot generally be satisfied using time-sharing scheduling algorithms and system structures. To effectively support these types of programs, operating systems must support processor capacity reservation. A capacity reservation and enforcement mechanism isolates programs from the timing and execution characteristics of other programs in the ...

In multimedia wireless networks, when a mobile host (MH) moves to a neighbor cell, it requests the base station (BS) to reserve the bandwidth for seamless handoff. The reservation scheme based on the fixed 2-tier cell structure was proposed to prevent the reservation requests from the MHs close to the BSs. In this reservation scheme, the BS requests the reservation only when the MH is outside o...

This paper studies media access protocols which support collision-free broadcast/multi-cast communication for optically connected star-coupled systems with Wavelength Division Multiple Access channels. An early hybrid access protocol, consisting of reservation and of receiver channels pre-allocation, allows reservation for exactly one WDM channel per node during the reservation phase. We extend...

Distributed lightpath establishment in WDM optical networks involves, apart from routing, two important steps, namely wavelength selection and wavelength reservation. In uni-wavelength reservation protocols, often multiple connection requests unknowingly compete for the same wavelength, even when other free wavelengths are available, resulting in a collision. Attempting multiple wavelengths for...

We present the design, implementation, and experimental results of our soft real time (SRT) system for multimedia applications in a general purpose UNIX environment. The SRT system supports several service classes for the real time processes based on their processor usage time pattern: periodic constant processing time(PCPT) class, aperiodic constant processing time(ACPT) class, variable proces...

We analyse and illustrate two approaches that we have developed for providing reservations to ows. The rst approach uses the explicit reservation model: a traac proole is negotiated between users and the network. ATM and RSVP are two examples for this approach. In this paper we describe our experience in the ACT project EXPERT (AC094) with the explicit reservation model in the context of ATM. W...
