As the limitations of energy consumption for real-time embedded systems more strict, it has been difficult to ignore the context switch overhead for Fixed-Priority task with Preemption scheduling (FPP) in multitasking environment. This paper presents a Reducing Context Switches scheduling (RCSS) based on preemption thresholds scheduling for real-time(More)
The Cyber-Physical Energy Systems (CPES) represent a new class of widely distributed and globally interconnected energy systems that integrate computation processes, communication processes and control processes. The architecture design and verification in a CPES development is a key works. In this paper, a new CPES application architecture is proposed(More)
Cyber-Physic System (CPS) is a new complex system that is integrations of computation and physical process with many networks and technologies. The communication system in electric vehicle (EV) charging station introduced in this paper consist of data collect terminals, data transmission networks and data processing gateway, so it is a typical application(More)
Sustainable computing provides different approaches towards design and verification of energy-sustainable computing in Cyber-physical system (CPS). A major issue is how to design energy management strategy for ensuring the sustainability of energy computing while the computation processes and physical processes are continued to interact in CPS. To solve(More)
For the shortcomings of current WebGIS decisionmaking systems development, such as complex resource data sharing, access control of complex user permissions, role customization, the architecture research and design is a key works in Web GIS development. In this paper, the portal technology and role-based access control is analyzed, and WebGIS architecture(More)
