Business Process Execution Language (BPEL) is considered as the de facto standard for Web service composition. To analyze the performance of composite service processes specified in BPEL gives the way to tell whether the process meets the performance requirements. In this paper, we propose a translation-based approach for performance analysis of BPEL processes, which employs a general stochastic Petri...
During last two decades, Mobile Ad hoc Networks (MANETs) has been in widespread use. However, in some critical applications such as in battlefield or area sensing, due to the node mobility, limited power and sparse deployment density, MANETs may suffer network partitioning. Without a stable end to end path, these challenged scenarios could cause most existing ad hoc networks protocols to fail. In...
In addressing the scalability and accuracy tradeoff in topology aggregation mechanisms with delay and bandwidth constraints in hierarchical networks, we propose a demand partitioning based topology aggregation mechanism called dominative points based topology aggregation (DPTA). The main drawback of traditional approaches is that these approaches use lines or curves to approximately represent the...
The method of reducing the integral interval by using the fractional order delay filter to improve the performance of fractional differential filter is put forward in this paper. Firstly, in terms of the basic definition of integral the paper generalizes the sampling interval of integral operator from the integral order to fractional order and gets the integral operator whose sampling interval is...
