Focusing on the problem that two HOS (Heterogeneous operating systems) of wireless sensor network can't communicate with each other, and based on the comparative analysis on common-use communication models for the node operating system, we had brought forward a heterogeneous operating system communication model for a wireless sensor network. It consists of two tactics: scheduling tactic and processing tactic, which work together to finish the heterogeneous operating system communication. We introduced mobile-agent mechanism and first come first serve scheduling algorithm to co-operate task scheduling in the model. Experimental results and preliminary applications show that the model provides a good way for heterogeneous operating system communication.

Web service composition lets developers create applications on top of service-oriented computing and its native description, discovery, and communication capabilities. This paper mainly focuses on the QoS when the concrete composition structure is unknown. A QoS model of service composition is presented based on the fuzzy directed graph theory. According to the model, a recursive algorithm is also described for calculating such kind of QoS. And, the feasibility of this QoS model and the recursive algorithm is verified by a case study. The proposed approach enables customers to get a possible value of the QoS before they achieve the service.

An abstract inference machine for producing discourse models in natural language understanding is be proposed. The machine has tableaux as it central data structure and can operate in model generation and theorem proving modes. In the method semantic analysis is be used analysis of semantic representations by inference on the basis of semantic information and world knowledge. Some potential applications of model generations and model generation theorem provers in the construction and analysis of natural language semantics are valuable sources of information.

The security of Web Services has become one of the important research topics about the application of Web Services. In this paper, we propose an agent-based policy aware framework for Web Services security. In this framework, a policy language called ReiT which is a declarative language based on the rules and ontologies is introduced The non-structural knowledge is represented by rules and the structural temporal knowledge is represented by ontology. Moreover, we propose a mixed reasoning mechanism to evaluate the ReiT policy. The access control policy including the context of the user and Web Services is evaluated by the reasoner. In addition, we present a policy aware BOID agent to authorize the access control of the Web Services. And we implement the policy aware BOID agent by extending the JADE platform.
Multilevel security policies aim at only confidentiality assurance, with less consideration on integrity assurance and weakness in expressing channel control policies. Besides, the trusted subjects it introduces to ha...

In open multi-agent systems (MAS), interaction between agents is uncertain. Trust plays an important role in deciding with whom to interact and how to interact with it. Current trust models have solved the problem of how to quantify, deduce and evaluate trust, but there are still challenges. This paper presents FIRE+ trust model using utility loss of issue to evaluate trust values. With the representation of matrix, it efficiently increases the rating information. Also by introducing D-S theory and WMA, it can handle uncertain information and dishonest witness finely. Meanwhile, our approach introduces the concept of information-amount to derive each issue's weight so as to gain the whole trust value of the target agent. It also takes witness reliability into account. Experiments show that FIRE+ is more effective than others.
