Abstract EN
As limited energy is one of the tough challenges in wireless sensor networks (WSN), energy saving becomes important in increasing the lifecycle of the network.
Data fusion enables combining information from several sources thus to provide a unified scenario, which can significantly save sensor energy and enhance sensing data accuracy.
In this paper, we propose a cluster-based data fusion algorithm for event detection.
We use k-means algorithm to form the nodes into clusters, which can significantly reduce the energy consumption of intracluster communication.
Distances between cluster heads and event and energy of clusters are fuzzified, thus to use a fuzzy logic to select the clusters that will participate in data uploading and fusion.
Fuzzy logic method is also used by cluster heads for local decision, and then the local decision results are sent to the base station.
Decision-level fusion for final decision of event is performed by base station according to the uploaded local decisions and fusion support degree of clusters calculated by fuzzy logic method.
The effectiveness of this algorithm is demonstrated by simulation results.
