Creating Based Network Services And Contributions of Social Cloud Operation Support System (OSS) to Society

ABSTRACT Emerging virtualization technologies are making ubiquitous access to on-demand computing, network and storage resources to deliver various applications over public Internet. In this paper we present how the telecom operation support systems (OSS) that provide Enterprise-to-Enterprise (E2E) transactions, switching management, on-demand service management and scalability have evolved to provide next generation cloud management. Fujitsu’s [...]

Performance Evaluation of Efficient and Reliable Routing Protocols for Fixed-Power Sensor Networks

ABSTRACT A Fixed–power wireless sensor networks are cost effective and prevalent, and they are facing lots of problems like RF interference, node failure from environmental noise and energy constraints. A routing protocol for Fixed – power wireless sensor networks must overcome these problems. Because it have to achieve reliability, energy efficiency and scalability in message [...]

What Networking of Information Can Do for Cloud Computing

ABSTRACT Cloud computing is making it possible to separate the process of building an infrastructure for service provisioning from the business of providing end user services. Today, such infrastructures are normally provided in large data centers and the applications are executed remotely from the users. One reason for this is that cloud computing requires a [...]
