Flexible real-time payment methods for mobile communications
The method o f hilling uscrs for niohilc tclcphony is hascd on systems dcvclopcd over time for fixed networks. We survey the technoloby involved, and argtic t h a t these systems will hcconic increasingly inadequate f o r large populations of niohilc users whcrc frequent roaming is involved. Wc prcscnt two micropaymcnt schemes which permit ;I callcr t o inject ;I payment stream into the network...
متن کاملFuzzy Motion Control for Wheeled Mobile Robots in Real-Time
Due to various advantages of Wheeled Mobile Robots (WMRs), many researchers have focused to solve their challenges. The automatic motion control of such robots is an attractive problem and is one of the issues which should carefully be examined. In the current paper, the trajectory tracking problem of WMRs which are actuated by two independent electrical motors is deliberated. To this end, and ...
متن کاملCognitive Radio for Flexible Mobile Multimedia Communications
Wireless multimedia applications require significant bandwidth, some of which will be provided by third-generation (3G) services. Even with substantial investment in 3G infrastructure, the radio spectrum allocated to 3G will be limited. Cognitive radio offers a mechanism for the flexible pooling of radio spectrum using a new class of protocols called formal radio etiquettes. This approach could...
متن کاملFlexible Scheduling Methods and Tools for Real-Time Control Systems
Embedded microcomputers are increasingly being deployed in modern engineering applications, and real-time control systems constitute an important subclass of these embedded systems. Modern automotive systems, e.g., contain several embedded ECUs (electronic control units) used for various feedback control tasks, such as engine performance control, anti-lock braking, active stability control, exh...
متن کاملA P2P Architecture to Support Mobile Real-Time Multimedia Communications
A new SIP standard based on peer to peer paradigm allows the keeping of user localization information in a decentralized way, adding flexibility to real-time mobile communications. Despite specification of terminal mobility in P2PSIP, handover procedures in transport-layer have better performance when compared with solutions in application-layer of Internet. SCTP transport protocol supports han...
