Back-propagation neural network (BPNN) for software reliability prediction has the problem of network architecture difficult to determine. We want to solve the problem and further increase the prediction accuracy of the model. We use phase space reconstruction technology and the fuzzy wavelet neural network (FWNN), and present the software reliability(More)
Data cubes are widely used as a powerful tool to provide multi-dimensional views in data warehousing and On-Line Analytical Processing (OLAP). However, with increasing data sizes, it is becoming computationally expensive to perform data cube analysis. The problem is exacerbated by the demand of supporting more complicated aggregate functions (e.g.(More)
Partitioning of complex networks, esp. of social networks, has been a hotly debated topic in academic circles in recent years. Since actual networks usually contain some boundary nodes that are difficult to assign to a certain community, soft partitioning is under great demand in practical applications. However, at present network partitioning is done(More)
Recently, mobility-enabled wireless sensor networks have been exploited to improve energy efficiency at the cost of increased latency. In this paper, we propose a Grid-based solution for Real-time Data Gathering application with mobile sinks (GRDG). Like many hierarchical structures, the flexible virtual grid partition scheme based on power control is(More)
Researches show that numerous complex networks have clustering effect. It is an indispensable step to identify node clusters in network, namely community, in which nodes are closely related, in many applications such as identification of ringleaders in anti-criminal and anti-terrorist network, efficient storage of data in Wireless Sensor Network (WSN). At(More)
In mobile computing environments, the limited bandwidth of wireless communications, the weak capability of mobile computing equipments and the valuable power make it difficult for mobile devices to be maintained with the network all the time. Cache technique caches part of data in the clients to reduce the query of database server, so it solves the problem(More)
Mobile databases are always the core technique of the dynamic data management. Cache technique, as one of the key techniques in mobile databases, is able to reduce the contention of bandwidth and save the power energy. As the character of ant colony algorithm is choice, update, cooperation mechanism, which is accorded with the mobile agent. An invalidation(More)
