Port is a basic parameter in TCP/IP data communication. However, a port by its number has no clear association to the types of applications. Identifying such an association, which is referred to as a port role...
“Pay only for what you use” principle underpins the charging policies of widely used cloud services that are on offer. Ideally for these services, consumers should be in a position to verify the charges billed...
Organizations face the ever growing challenge of providing security within their IT infrastructures. Static approaches to security, such as perimetral defense, have proven less than effective — and, therefore,...
Intra-domain virtual network embedding is a well-studied problem in the network virtualization literature. For most practical purposes, however, virtual networks (VNs) must be provisioned across heterogeneous ...
Cloud Computing is a flexible, cost-effective, and proven delivery platform for providing business or consumer IT services over the Internet. However, cloud Computing presents an added level of risk because es...
Super-peer overlay provides an efficient way to run applications by exploring the heterogeneity of nodes in a Peer-to-Peer overlay network. Identifying nodes with high capacity as super-peers plays an importan...
Network virtualization is a promising technique for building the Internet of the future since it enables the low cost introduction of new features into network elements. An open issue in such virtualization is...
The growing ubiquity of Internet and cloud computing is having significant impact on media-related industries. These industries are using the Internet and cloud as a medium to enable creation, search, manageme...
The wide variety of scientific user communities work with data since many years and thus have already a wide variety of data infrastructures in production today. The aim of this paper is thus not to create one...
Morlet continuous wavelet transform (MCWT) has been widely used to process non-stationary electro-encephalogram (EEG) data. Nowadays, the MCWT application for processing EEG data is time-sensitive and data-int...
Future Internet technologies and the deployment of mobile and nomadic services enable complex communications networks, that have a highly dynamic behavior. This naturally engenders route-discovery problems und...
Cycle sharing over the Internet has increased in popularity during the last decade, with increasingly powerful machines being made available to existing projects. In this paper, we present GiGi-MR, a framework...
The massive increase in data volume with the development of computation capability has outmoded compute-intensive clusters for the analysis of large-scale datasets due to the network bottleneck caused by the l...
Today there are many location technologies providing people or object location. However, location privacy must be ensured before providing widely disseminated location services. Privacy rules may depend not on...
In this paper, a distributed controller for a virtualized router is proposed. This controller enables the dynamic and automatic resource allocation between the different virtual routers (called slices) running...
Nowadays e-mail spam is not a novelty, but it is still an important rising problem with a big economic impact in society. Spammers manage to circumvent current spam filters and harm the communication system by...
In many situations, searching the web is synonymous to information seeking. Currently, web search engines are the most popular vehicle via which people get access to the web. Their popularity is partially due ...
Runtime reconfigurable component models provide several attractions with regard to the management of wireless sensor network (WSN) applications operating in dynamic environments and under evolving application ...
Within modern internet infrastructure including networks that are ubiquitous, there is often a need for delegatable communication between nodes without compromising the confidentiality of information. In pract...
With the growth, ready availability and affordability of wireless technologies, proactive context-aware recommendations are a potential solution to overcome the information overload and the common limitations ...
The use of Web services in enterprise applications is quickly increasing. In a Web services environment, providers supply a set of services for consumers. However, although Web services are being used in busin...
With the increasing use of autonomic computing technologies, a Java Enterprise Edition (JEE) application server is implemented with more and more adaptive computations for self-managing the Middleware as well ...
Data interoperability is one of the main problems of system interoperability. Indeed, it is estimated that the cost of data interoperability ranges in the billions of dollars every year. The traditional approa...
In this paper, we address the role of middleware in enabling robust and resilient cyber-physical systems (CPSs) of the future. In particular, we will focus on how adaptation services can be used to improve dep...
One main issue associated with the efficient and effective use of heterogeneous resources in a grid system is the scheduling. Scheduling in a grid system involves a number of challenging issues mainly due to t...
Key concepts of reliable distributed computing developed during the 1980s and 1990s (e.g., transactions, replication) influenced the standards based middleware such as CORBA and Java EE. This middleware has ev...
Cloud computing is by far the most cost-effective technology for hosting Internet-scale services and applications. The MapReduce model, in particular, is largely used nowadays in Cloud infrastructures to meet ...
Cloud computing offers a number of benefits, such as elasticity with the perception of unlimited resources, self-service, on-demand, automation, etc. However, these benefits create new requirements for managem...
Highly complex distributed systems (HCDSs) are characterized by a large number of mission-critical, heterogeneous inter-dependent subsystems executing concurrently with diverse—often conflicting—quality-of-ser...
In this paper, we explore the integration of evolutionary computation into the development and run-time support of dynamically-adaptable, high-assurance middleware. The open-ended nature of the evolutionary pr...
Coordinating the networks needed for modern scientific data collection and control presents a significant challenge: they are typically power- and resource-constrained, operating in noisy and hostile environme...
The exposure of business applications to the web has considerably increased the variability of its workload patterns and volumes as the number of users/customers often grows and shrinks at various rates and ti...
Contemporary middleware must facilitate the customization of a built-in services framework, such that non-functional requirements emerging from the engineering process are met. This must be achieved by facilit...
This paper considers mission assurance for critical cloud applications, a set of applications with growing importance to governments and military organizations. Specifically, we consider applications in which ...
What is a highly complex distributed system in the future era? What are the needs that may drive the development of such systems? And what is their life cycle? Is there any new challenge for Software Engineeri...
In modern distributed computing, applications are rarely built directly atop operating system facilities, e.g., sockets. Higher-level middleware abstractions and systems are often employed to simplify the program...
Social computing broadly refers to supporting social behaviours using computational systems. In the last decade, the advent of Web 2.0 and its social networking services, wikis, blogs, and social bookmarking h...
Many modern distributed systems are required to scale in terms of their support for processes, resources, and users. Moreover, a system is often also required to operate across the Internet and across differen...
Programming languages have long impacted the development of distributed systems. While much middleware and distributed systems code continues to be developed today using mainstream languages such as Java and C...
We analyzed how reliability will be improved by adopting inter-domain multi-path and multi-homing routing when the structure in the Internet changes. We identified the properties of the ideal network structure...
