This article presents the design and implementation of a dynamic mobile sensor network platform consisting of stationary sensors, mobile sensors, mobile sensor gateways, and sink servers. The sensor network platform supports heterogeneous protocols in the network layer and performs ID-based communications to deliver sensor data from the sensors to the sinks, as well as to send control and monitoring...
The wireless ubiquitous network and various communication services are expected to be realized. The wireless ubiquitous network is defined as the converged network to integrate the mobile network with the fixed IP based network. First, the concept of wireless ubiquitous network architecture is shown which is based on IMS standardized by 3GPP. Next, Parlay is described as the solution of Open API approach...
There is a rapid growth and evolution in the area of telecommunications and network operators are expected to provide seamless integration of all communication applications on a single system. In these circumstances IMS has emerged out as a key player. IMS is basically a network architecture consisting of an IP-based core network connected to multiple access networks to provide a converged service...
Applications on network need not only enough quality of service (QoS) but also enough quality of security service (QoSS) because the security is essential for most of applications on network. The purpose of QoSS is to organize various security services together to achieve enough security for applications. As security requirements vary dramatically for different applications, differentiated security...
