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 [...]
Security Challenge and Defense in VoIP Infrastructures
ABSTRACT Voice over Internet Protocol (VoIP) has become a popular alternative to traditional public-switched telephone network (PSTN) networks that provides advantages of low cost and flexible advanced “digital” features. The flexibility of the VoIP system and the convergence of voice and data networks brings with it additional security risks. These are in addition to the [...]
