A Path Planning Method for Water Surface Mobile Sink Based on Voronoi Diagram and Bipartite Graph
摘要
Abstract
In surface sensor networks with sparsely deployed sensors, the distance between sensors is usually larger than the communication radius of sensors. So, it is difficult for sensors to gather their data by multi-hop routing. At present, an effective data gathering method is to use a mobile sink travelling in the network, and the path planning for the mobile sink becomes a key problem. In this paper, a path planning method based on Voronoi diagram and bipartite graph is proposed. Firstly, the data gathering “candidate vertexes” are generated using the Voronoi diagram theory. Secondly, a bipartite graph is constructed to describe the dominating relationship between candidate vertexes and sensors, and the “minimum effective dominating set”, which includes the least candidate vertexes gathering all sensors data, can be computed by dominating set theory. Lastly, the optimal path is formed based on the minimum effective dominating set. Extensive experiments have demonstrated that the proposed method can effectively plan the path for mobile sink to gather all sensors0 data with advantages such as short path, high energy efficiency, and balanced energy consumption among sensors.关键词
