Clustering Based Optimal Data Storage Strategy Using Hybrid Swarm Intelligence in WSN

摘要

In most wireless sensor network applications a large amount of data has been continuously collected for future data query and analysis. Data storage management becomes an important challenge in wireless sensor networks. A popular application of sensor networks is event monitoring. In such applications, the observers may not be interested in the sensors or the raw data from the sensors, but more interested in the events. To address the issues of data storage for event monitoring, an optimal data storage scheme is proposed specifically for Fire detection event. In this work, mainly storage node position problem is considered. Hybrid particle swarm optimization is integrated with FCM clustering to attain the suitable positions for k storage nodes in WSN based on the energy cost of data transmission which in turn assists in the detection of the fire event. To reduce data access energy consumption, FCM clustering based on data storage (CBDS) algorithm has been proposed. CBDS has appropriately adapted to adjust the location of data storage through the process of data storage and query access cost calculations respectively. This paper is focused on monitoring the fire event detection in WSN based on the hybrid PSO with FCM clustering.
