Dynamic QoS Mechanism for supporting VoIP Service in Tactical Communication Environment

Quality of Service (QoS) in Wireless Network, VOIP Simulation Environment

A Quality of Service (QoS) is determines if a wireless technology can successfully deliver high value services such as voice and video. The PHY and MAC layers of 802.16 are described in detail with regarding their QoS. The relations and interactions of these QoS mechanisms are described to give an understanding them. The UGS service flow can handles the traffic generated by VOIP calls in the mo...

Effective QoS Aware Web Service Composition in Dynamic Environment

Nowadays, several web services composition approaches, each considering various aspects of the composition problem, are known. Consequently, a lot of attention shifts to the performance issues of web service composition. This paper presents an effective QoS aware composition approach. Our work focuses to its performance, which is studied also in dynamically changing environment, where new servi...

A QoS-aware composition method supporting cross-platform service invocation in cloud environment

With the increasing popularity of cloud computing technologies, more and more service composition processes are enacted and executed in could environment. Compared with the various and approximately infinite application requirements from end users, the web services held by a cloud platform is usually limited. Therefore, it is often a challenging effort to develop a service composition, in such ...

QoS prediction for Web service in Mobile Internet environment

QoS prediction plays an important role in Web service recommendation. Many existing Web service QoS prediction approaches are highly accurate and useful in Internet environments. However, the QoS data of Web service in mobile Internet is notably more volatile, which makes these approaches fail in making accurate QoS predictions of Web services. In this paper, by weakening the volatility of QoS ...
