Client-server architecture is the common practice for online games where installed reliable servers provide the game logic. If the latency between two players through a server is large, the responsiveness of the game can become problematic. Consequently, performance as well as gaming experience can be unsatisfactory. In this paper, for client-server architecture we present a game state forwarding...
Control networks are widely deployed on mass produced mobile systems such as automotive systems, airplanes, and mobile robots. Previous works on control networks have focused on guaranteeing controllability, predictability, and dependability in the time domain because control networks manipulate actuators directly, and hence are highly related to safety. However, in contrast to data networks, control...
In this paper, we study the delay-constrained message delivery capacity formulation in mobile wireless networks. The message delivery capacity specifies the maximum percentage of messages that can be successfully delivered to base stations within a given time constraint. By taking full advantage of node mobility and rendezvous during mobile node encounter, messages can be delivered to a base station...
The peer-to-peer (P2P) live video streaming system has been demonstrated to have great potential in the public Internet; the large-scale deployment of such systems, however, critically relies on how effective they can deal with the high dynamics encountered, in particular during flash crowd. The rationale behind is that the scaling in P2P live video streaming systems is heavily determined by the timing...
Temporal aspects have a vital importance while dealing with the verification of critical systems. Time constraints may reflect both security and performance requirements. Thereby, verifying the temporal requirements is a major task in the validation of critical systems. In this paper, we discuss a new approach for the specification of the temporal requirements within complex systems. We also sketch...
The behavior of real-time systems depends not only on their interaction with the environment but also on very rigid time constraints that puts restrictions on when these interactions take place. The timing aspect of such systems renders the testing process difficult without defining adequate test selection criteria that ensure good coverage of the system while keeping the number of needed test cases...
