Wireless sensor networks (WSN) are used in many spheres, such as industry, commerce and military. WSN is composed of hundreds of thousands of sensor nodes with limited energy, computation and storage capacities. Thus the data aggregation technique becomes important because it can help to improving bandwidth usage and energy utilization. But the unprotected aggregation schemes are vulnerable because WSN often placed in untrust or even hostile environment, so the researches on secure aggregation become meaningful. Most prior works have focus on both data aggregation techniques and security techniques, but the researches on secure data aggregation were still few. In this paper, we focus on the integrality of data aggregation and present a resilient in-network data aggregation scheme for wireless sensor networks deploy in hostile environment.

With the emergence of more and more XML documents, effectively and efficiently retrieving information from XML documents has become an active research area. Since XML documents lie between structured data and unstructured data which describe both content and structure, it is a huge challenge for effectively and efficiently retrieving information from XML documents. This paper develops a novel retrieval model named as Extend Vector Space Model which effectively combines XPath and Vector Space Model for XML information retrieval. A prototype system for XML information retrieval based on this retrieval model has been implemented, and several corresponding algorithms have been introduced. The experiments show that this model has effectively improved recall and precision.

A new method based on kernel which can measure class separability in feature space is proposed in this paper for existing error accumulation when the Hierarchical SVMs is used to diagnose multi-class network fault. This method has defined metrics of sample distribution in feature space, which are used as the rule of constructing Hierarchical SVMs. Experiment results show that this method can restrain error accumulation and has higher multi-class classification accuracy, and offer an effective way for Network fault diagnosis.

To solve the problem of organization and maintenance of massive grid geographic data, this paper present a multi-pyramid mixed organization model basing on the research of original pyramid model. In multi-pyramid model, a main pyramid could include some sub pyramid. Each sub pyramid is independent and can be deployed to different host. The paper also discusses the schedule method of grid data in different data organization model when grid data are displayed in the window, and achieved good effect in practice.

With the increasingly widespread application of the network, a distributed operating system based on Linux cluster has been developing rapidly. This paper presents a kernel level distributed interprocess communication system model with support for distributed process synchronization and communication. This system model uses the System V interprocess communication programming interface and enhances it to provide functionality in distributed environments. A key feature of this system model is the use of the semaphore interface to support distributed synchronization and the implementation is done at the Linux kernel level to reduce the overhead. Finally, we realized this model introduced in this paper in redhat Linux cluster and test result show it is a good solution of distributed processes communication. Compared with other similar systems, the advantage of this system is that the implementation is done at the Linux kernel level to reduce the overhead and System V IPC API is easy to extend. User is easy to call the application interface of the distributed operating system, without considering any details of the network.
