Evolution towards the Future (Internet) networks necessitates inclusion of self-management capabilities in modern network infrastructures, for a satisfactory provision of related services and for preserving network performance. We have considered a specific targeted methodology, in the form of the generic cognitive cycle model, which includes three distinct processes (i.e. Monitoring, Decision ...

Nowadays, one of the problems of human life is popula- tion congestion and the lack of ability to meet their needs. One of the important infrastructures affected by this issue is the transportation infrastructure. Moreover, increasing transportation facilities through conventional methods, due to the need for macro investment and much time, cannot be nowadays considered as a proper and practi- ...

How do complex societal demands and time constraints posed by distributed temporary organizing affect organizational communication? Extending Bowker and Star’s (2002) work on infrastructures, we introduce two context-specific ‘invisible’, social infrastructures: organizational and relational. We empirically assess their role in an international, multi-site ERP-software implementation. We invest...

Critical Infrastructures include facilities, services and installations essential for the functioning of a society and economy. Such infrastructures are generally of a very large scale spanning cities, whole countries, or even crossing international borders. Examples of such Large-Scale Critical Infrastructures (LSCI) are electricity, water and gas supply, transportation, and health service [8]...

Future infrastructures for energy, traffic, and computing will be virtualized: they will consist of decentralized, self-organizing, dynamically adaptive, and open collections of physical resources such as virtual power plants or computing clouds. Challenges to software dependability, in particular software security will be enormous. We use the example of smart power meters to discuss advanced t...
