While the conventional remote method invocation mechanism has been considered for a long time as the primary approach for facilitating interactions among real-time objects, a multicast support mechanism has been recognized in recent years as an attractive supplement, if not a favored approach, in many applications. One highly promising concrete formulation(More)
Software techniques which enable efficient construction of sensor networks that are easily analyzable and can rarely run into a chaotic situation are in high demands. With the motivation for developing such software techniques, a skeleton of a software architecture for sensor networks which uses time-triggered functions (TTFs) extensively has been(More)
The largely synchronous sensor network software architecture (LaSSeNSA) was formulated with the goal of enabling efficient construction of sensor networks that are easily analyzable and can rarely run into a chaotic situation. There are largely three parts in LaSSeNSA; (1) Global time based coordination of uses of shared communication channels; (2) Global(More)
For cost-effective realization of sizable realtime distributed computing application systems, significant advances in resource allocation are in critical needs. An advanced practical scheme for high-level programming of real-time distributed computing software such as the TMO (Time-triggered Message-triggered Object) scheme introduces the potential for(More)
In order to solve the disadvantage of current ant colony optimization algorithm (ACO) which easily plunged into local optimal in dealing with Multi-Satellite Scheduling Problem (MuSSP), a hybrid ant colony optimization algorithm (HACO) is proposed. In this method, the ACO algorithm is served as a global search algorithm. According to the characteristics of(More)
Programming and composing deterministic distributed real-time systems is becoming increasingly important, yet remains difficult and error-prone. An innovative approach to such systems is the general-form timeliness-guaranteed design paradigm, which is the basis for the time-triggered message-triggered object (TMO) programming and system specification(More)
The use of network in a control loop has gained increasing attentions in recent years. One of the major challenges in this networked control system (NCS) is the network-induced delay effect in the control loop. Network delays can degrade the NCS performance and even destabilize the system. A lot of scholars focus on developing control methodologies to(More)
