The rapid growth in market demands for high-quality, state-of-the-art, and reliable communication services increases the amount of session-control signaling, which is mainly based on the Session Initiation Protocol (SIP). Many research activities dealing with the Quality of Service (QoS) have been focused on media-related service components, whereas signaling-related service components have received...
This work proposes the use of a weighted Finite State Machine to serve as a computational model for analyzing the performance of communication protocols. The new model's use is demonstrated by concentrating on web-based services, Internet level-5 protocols in particular, because when the latter are ported onto mobile handsets, fail to meet performance expectations. The same modeling technique can...
There has been a rapid growth of services based on session control. Session-based services comprise multimedia conferences, Internet telephone calls, instant messaging, and similar applications consisting of one or more media types such as audio and video. Deployment examples include session control services as part of the IP multimedia subsystem (IMS), in the third-generation mobile networks. High...
