The back-end intelligent system of Internet of Things (IoT) needs the powerful computing ability to support its service, and therefore, IoT is often constructed on the cloud platform. However, the resources for cloud computing are limited, and different types of services will have different demands for the resources. This paper proposed a service-oriented virtual machine (VM) placement strategy in...
In recent years, there are various cloud storage services have been proposed. The users can acquire the enormous cloud storage spaces through Internet even if the storage space of portable devices and handsets are limited. In this paper, we implement a distributed file system based on Apache Hadoop, and the original Hadoop distributed file system is replaced with the Tahoe least-authority file system...
In recent years, multimedia network services have moved from a single service to rich services which integrate multiservice capabilities integration. If all service requests require the user to send the request by himself, this will result to a huge control function load and complex service collaboration. In order to address service interaction and reuse the service capability, 3GPP proposes a Service...
The packet-switched NGN (Next Generation Network) architecture allows users to access multimedia services via the Internet anytime and anywhere. Through the core IP Multimedia Subsystem (IMS), NGN can provide multimedia services, such as voice, video, data and messages over heterogeneous networks. However, for high-quality services in practical environment, the performance and QoS (Quality of Service)...
Because of the demand of the various situation of fire and related disaster development, there exists an universal phenomenon in Chinese firefighting troops that the new rescue activity of extinguish fire needs to pass across regions.
