In this paper, a new network topology control mechanism is proposed to improve routing path duration in Aeronautical ad hoc network, which can effectively decrease the probability of routing path breaks in the process of nodes high-speed moving, and be integrated with existing routing protocols used in Ad hoc network smoothly. The main principle of topology control mechanism is according to the different...
High Performance Computing (HPC) leverages cluster combined with a set of computing nodes exploiting computational capacities to handle varying job submission for scientific computing work. Inappropriate capacity planning and related management mechanism applied, will lead HPC cluster into a rather large number of pending jobs which is considered as a critical factor to affect System's throughput...
Self-healing system attempt to enable computing systems to automatically discover, diagnose, and repair (or at least mitigate) faults without human intervention, thus it is a potential approach to improve the dependability and autonomy of computing system. A model-driven approach for modeling and analyzing the self-healing computing system is proposed in this paper. In our approach, the function part...
This paper proposes a six-layer conceptual architecture for spontaneous service provision. In the architecture, techniques of context-aware, semantic reasoning and service composition are smoothly synthesized. A dynamic service composition mechanism based on directed attributed graphs is introduced on the basis of functional characteristics of architecture. It maintains a repository of service graphs,...
This paper describes the core of an spontaneous service provision framework offering general functionality based on objects in Internet of Things. The framework supports sensor, wireless network and end system based on services and service features. The framework is more generic than traditional hierarchical sensor and actuator networks framework. It supports grids and spontaneous service provision...
In this paper, we take the interoperability and collaborative problems among various objects belong to different smart space into account and propose the features for object service provision in smart space. On the basis of the above features, we give a semantic and automatic framework for objects service in smart space. In the framework, techniques of object service provision, context-aware, semantic...
A multilevel trust management framework in pervasive environment is proposed in this paper. In the framework, the trust, the reputation, reciprocity and related concepts are defined newly. The multilevel discrete trust metric finds a good way to solve the problems, which the granularity of binary trust is coarse and the calculation of continuous trust is complex. The design of storage counter in the...
A semantic and automatic framework for network smart space is proposed in this paper. In the framework, techniques of spontaneous service provision, context-aware, semantic reasoning, and pervasive service management are smoothly synthesized. A six-layer conceptual architecture is introduced on the basis of functional characteristics of framework. It enables objects in network smart space to interact...
Aiming for the efficiency and quality of teaching in the resource restricted environments. The first, the authors analyze the fall short of traditional teaching-method, these shortages make against bring up project practice ability of undergraduate, the second, some solutions are point out. These include, fully using of network multimedia to improve the students' self-learning ability, increase in...
Chimney-like directory agent service location Protocol and mesh-connection directory agent mesh service location protocol are the two main hybrid service discovery mechanisms. However, it is reasonable to improve network performance by optimizing local unit size from the opinion of both sociology and network optimization. Based on the theory of "small-world network" of Watts and Strogatz,...
Software Radio, considered as a new technology for wireless communication area, implements various communication standards on a uniform hardware by moving calculational tasks onto Digital Signal Processor (DSP). As a result, demanding for DSP's calculational capabilities is growing and general purpose DSPs is incompetent for the works. In addition, general purpose DSPs' power and cost are not satisfying...
As data transfer rates become higher, general processor is not competent for works with high computing intensity in wireless communication area. The other hand, existing baseband processors lack adaptive ability to support new applications and newer versions of existing application. Thus the paper puts forward a novel architecture of reconfigurable stream processor along with application-specific...
In a partially reconfigurable system with online placement algorithm, we try to avoid mapping some redundant tasks by caching modules on the reconfigurable area. This paper proposes an elaborate strategy named virtual deletion and a low cost board- level hardware named recycle cache to accomplish the goal. In our strategy, the record of corresponding module is deleted from placer and indexed in the...
