Spatial-Temporal Information Integration Framework Based on Mobile-Agent in Wireless Sensor Networks

摘要

This paper presents a framework for spatio-temporal information integration based on mobile agent in wireless sensor networks. The ideas are introduced based on the fact that nodes with valued information are usually space-time varying in a sensor field. In the framework, one rhythm is defined as a period of time triggered by an object detection signal (ODS) message, in which ODSs from nodes are collected and analyzed to program the visiting itineraries for mobile agents. A rhythm acts as a label for spatial processing, and thus the series of rhythms become a time axis for temporal integration. In addition, the relations among some key parameters of framework are discussed. Finally, results based on experiments of collaborative target recognition demonstrate the effectiveness of the proposed framework.
