Mobile Agent based Data Fusion for Wireless Sensor Networks with a XML Framework

摘要

In Wireless Sensor Network, data fusion or data aggregation is the key technology to decrease power consumption and improve accuracy of data collection. This paper proposes a new data fusion approach which is based on the mobile agent technology. It uses mobile agent communication to decide the filtering or merging on data. It also makes use of XML as the expressive mechanism for sensed data, topology of network, and agent inner framework. An experiment is designed to evaluate the proposed approach with the existing data fusion technology. It is found that the new approach exhibits better performance in data fusion efficiency and power consumption saving.
