Scheduling algorithms aim to minimize the completion time and maximize the throughput of multiple tasks. However, traditional scheduling schemes cannot satisfy the requirements of internet-based virtual computing environment which contains massive and heterogeneous computing resources. Furthermore, continuously emerging internet applications are based on virtualcomputing, even worsening the situation. In this paper, a scheduling optimization algorithm is proposed to achieve application-oriented resource scheduling. computing resources are classified by their static properties in advance and ranked according to their performance grade, then tasks are marked according to their requirements, and finally a "resource sliding window" model is employed to perform resource scheduling according to the properties and requirements of tasks, achieving the goal of "proper resources serving proper tasks". Besides, the proposed algorithm suppresses traditional scheduling algorithms in load balancing which is sacrificed by many scheduling algorithms for minimizing completion time. Experimental results demonstrate that the proposed scheduling scheme effectively improve resource utilization and success rate of task execution.

In the internet-based virtual computing environment, a virtual commonwealth consists of a set of autonomic elements which have the same interest and obey the common principle. In the environment with open weak constraint, autonomic elements join or quit any virtual commonwealth freely. Because all the autonomic elements are free and uncontrollable, this introduces a risk of executing efficiency and the stability in the virtual commonwealth. This paper proposes a trust mechanism in internet-based virtual computing environment, to measure and represent the trust value of an autonomic element. By comprehensive consideration of the importance of the task, the proposed mechanism chooses the autonomic element which has corresponding trust value to improve the efficiency of task execution and the success rate.

The initiative of internet-based virtual computing environment （iVCE） aims to provide the end users and applications with a harmonions, trustworthy and transparent integrated computingenvironment which will facilitate sharing and collaborating of network resources between applications. Trust management is an elementary component for iVCE. The uncertain and dynamic characteristics of iVCE necessitate the requirement for the trust management to be subjective, historical evidence based and context dependent. This paper presents a Bayesian analysis-based trust model, which aims to secure the active agents for selecting appropriate trusted services in iVCE. Simulations are made to analyze the properties of the trust model which show that the subjective prior information influences trust evaluation a lot and the model stimulates positive interactions.
