RFID middleware plays an important role in enterprise applications such as integrating heterogeneous devices, processing data and events, providing uniform application interface and so on. However, some problems RFID middleware developers have to face are how to specify the quality of service for high level applications, how to transmit the RFID data efficiently, and how to consist the abilities of...
This paper proposes a novel scheme for monitoring and analyzing the performance of Internet applications based on statistical analysis. In our study, an Internet application is considered as a ldquoblack boxrdquo as the internal architecture and the operation/data flow of most of the applications is often unknown to enterprises or internet service providers. Our scheme discovers the underlying relationship...
In this paper, we put forward a model of multi-agent based on intrusion detection system for wireless sensor networks, and a new method of detection called refined clustering, which is suggested running on some agents. In this new method we use self-organizing map (SOM) neural network to cluster roughly the samples, and the next step the K-means clustering algorithm is adopted to refine the clustering...
Effective management of a supply chain requires the ability to detect unexpected variations at an early stage, which brings the possibility of taking preventive decisions to mitigate the variations. This paper proposes a methodology that monitors the dynamic trends of supply chain performance indicators, and gives early-warnings for potential risks. Initially, a supply chain model is built using system...
