The recent developments in remote healthcare systems have witnessed significant interests from IT industry (Microsoft, Google, VMware etc) that provide ubiquitous and easily deployable healthcare systems. These systems provide a platform to share medical information, applications, and infrastructure in a ubiquitous and fully automated manner. Communication security and patients' data privacy ar...

Live migration enables a running virtual machine to move between two physical hosts with no perceptible interruption in service. This allows customers to avoid costly downtimes associated with hardware maintenance and upgrades, and facilitates automated load-balancing. Consequently, it has become a critical feature of enterprise class virtual infrastructure. In the past, live migration only mov...

With the turn of this century, many researchers started showing interest in Embedded Firewall (EF) implementations. These are not the usual firewalls that are used as checkpoints at network gateways. They are, rather, applied near those hosts that need protection. Hence by using them, individual or grouped network components can be protected from the inside as well as from external attacks. Thi...

This paper presents a duplication-less storage system over the engineering-oriented cloud computing platforms. Our deduplication storage system, which manages data and duplication over the cloud system, consists of two major components, a front-end deduplication application and a mass storage system as backend. Hadoop distributed file system (HDFS) is a common distribution file system on the cl...

In this paper we have addressed the delay problem for real time control system. Real time control systems response is critical for any abnormal condition. We have modeled a communication and control system for system delay by using dymonda software that describes both the system hardware and software conditions. We have programmed an echo server and client application on VMware player for a par...

In this paper, we introduce accountable virtual machines (AVMs). Like ordinary virtual machines, AVMs can execute binary software images in a virtualized copy of a computer system; in addition, they can record non-repudiable information that allows auditors to subsequently check whether the software behaved as intended. AVMs provide strong accountability, which is important, for instance, in di...

Managing resources at large scale while providing performance isolation and efficient use of underlying hardware is a key challenge for any cloud management software. Most virtual machine (VM) resource management systems like VMware DRS clusters, Microsoft PRO and Eucalyptus, do not currently scale to the number of hosts and VMs supported by cloud service providers. In addition to scale, other ...

Virtualization tools are becoming popular in the context of Grid Computing because they allow running multiple operating systems on a single host and provide a confined execution environment. Emulators and experimental tools like Microgrid and PlanetLab use multiple virtual nodes on every platedorm nodes. Thus, to build a large scale emulator for Grid/P2P experiments, developers have to select ...

How can one recognize coordination languages and technologies? As this report shows, the common approach that contrasts coordination with computation is intellectually unsound: depending on the selected understanding of the word “computation”, it either captures too many or too few programming languages. Instead, we argue for objective criteria that can be used to evaluate how well programming ...
