A multi-agent system (MAS) for supporting the planning of transhipments of imported finished vehicles via a seaport is presented. The focus is on storage allocation, i.e. the allocation of parking areas for the temporary storage of vehicles, and on deployment scheduling, i.e. the allocation of drivers to the vehicles that have to be moved in the terminal area. These planning tasks, which in pra...

Solid State Drive (SSD) is believed to be the replacement for magnetic disk in computer systems. SSD is a complex storage device composed of flash chips, controller hardware, and proprietary software that together provide a block device interface via a standard interconnect. Comparing to its fast sequential read/write and random read operations, the random write on SSD is generally believed to ...

This chapter provides the reader with the ability to have a general appreciation of hardware and software, and data communication hardware and software in particular. It will raise an awareness of the need for networks to conform to international standards and for strategies to be developed to allow this transmission to be made. The importance and use of Local Area Networks (LANs) and Wide Area...

This paper presents a new mathematical framework of a Scalable Mobility Model (SMM) to characterise user movement behaviour, which can be applied to a wide number of network scenarios ranging from Local Area Networks (LAN) to Wide Area Networks (WAN). The core technique to describe the spatial and temporal behaviour of mobile users is the introduction of a novel concept referred to as Pole of G...

Radio resource (bandwidth) and power are limited in wireless personal networks. So these scarce resources are to be used efficiently from the system’s perspective while they should be allocated fairly or differently depending or users’ requirements or traffic characteristics from individual user’s perspective. We propose an integrated and efficient piconet and scatternet scheduling mechanism. I...

PANEL SUMMARY In recent years, data communication has overtaken voice as the main force behind the growth in wireless. With this has come a proliferation of standards ranging from wide area networks at one end of the spectrum to personal area networks on the other end. The opportunities offered by this truly ubiquitous connectivity are tremendous, and are leading to revolutionary chances in the...

IEEE 802.11e specifies the Enhanced Distributed Channel Access (EDCA) for distributed access with traffic differentiation to a Wireless Local Area Network (WLAN). Traffic differentiation led to introducing several traffic queues within each station, thus introducing virtual collision. In this paper, we present a pattern based Markov chain model of EDCA including the virtual collision phenomenon...

Cluster of standard servers are rapidly gaining popularity as an alternative for mainframe systems. Distributed and high performance applications running over these clusters require high performance communication subsystem. The proprietary network configurations developed for Systems Area Networks (SAN) so far have remedied this but have limited the scalability of the system because of high cos...

This paper presents a rather simple method to model cluster architectures using Stochastic Automata Networks (SAN) formalism. Although, the modeling power of SAN, the presented models are quite simple and do not fully describe the complexity of existing clusters. It is not the purpose of this paper to proposed ready-to-evaluate models to real clusters, but just introduce the formalism to the pa...
