This article investigates and evaluates a handover exchange scheme between two secondary users (SUs) moving in different directions across the region of neighboring cell cognitive radio network. More specifically, this investigation compares performance SUs cellular network with without channel scheme. The shows reduced failure, blocking, forced access probabilities respectively, for buffer as ...

Antibody microarrays are a developing tool for global proteomic profiling. A protocol was established that permits robust analyses of protein extracts from mammalian tissues and cells rather than body fluids. The factors optimized were buffer composition for surface blocking, blocking duration, protein handling and processing, labeling parameters like type of dye, molar ratio of label versus pr...

This paper proposes a novel service differentiation mechanism utilizing optical buffers in transparent optical networks. We first introduce fiber delay line (FDL)-based optical buffers and propose a hybrid shared optical buffered node. Based on the proposed buffer, diverse service requirements can be satisfied by assigning different priorities on accessing the buffer. Since the blocking perform...

Optical burst switching (OBS) is a promising technology for the next generation optical Internet. A buffer-less OBS network can be implemented using ordinary optical communication equipment without the need for either wavelength converters or optical memories. However, OBS networks suffer from a relatively high blocking probability, a primary metric of interest, because of contention. In this p...

In this paper2 we present a routing mechanism and buffer allocation mechanism for an ATM switching fabric. Since the fabric will be used to transfer multimedia traffic it should provide a guaranteed throughput and a bounded latency. We focus on the design of a suitable routing mechanism that is capable to fulfil these requirements and is free of deadlocks. We will describe two basic concepts th...

The use of buffer thresholds, blocking and adequate service strategies are well-known techniques for computer networks traffic congestion control. This motivates the study of series queues with blocking, feedback (service under Head of Line (HoL) priority discipline) and finite capacity buffers with thresholds. In this paper, the external traffic is modelled using the Poisson process and the se...

Storage or buffer capacities between successive machines in flowshop problems may be unlimited, limited or null. Two last cases can lead to blocking situations. In flowshop scheduling literature, many studies and research were realized about classical flowshop problem and also about some problems with only one blocking situation. This paper deals with makespan minimization in flowshop schedulin...

A high performance packet switching architecture called the Pipeback switch is proposed. This architecture ensures lossless packet delivery while maintaining linear buffer complexity. The Pipeback switch improves upon the popular Knockout switch proposed by Y. Yeh et al. Both switches use an N × N space division fabric with output queuing and both designs are motivated by the observation that t...

Based on our analysis of the behavior of standard UNIX communication software, we propose a new communication mechanism which reduces software overhead. This mechanism is optimized to be used in business applications, such as those of online transaction process ing and da tabase managemen t . These applications are currently designed to operate i n mul t ip le concurrent processes , thus requir...
