Abstract:

Clustering-based sensor-management schemes have been widely used for various wireless sensor networks (WSNs), as they are well suited to the distributive and collaborative nature of WSN. In this paper, a C60-based clustering algorithm is proposed for the specific planned network of space tracking and surveillance system (STSS), where all the sensors are partitioned into 12 clusters according to the C60 (or football surface) architecture, and then a hierarchical sensor-management scheme is well designed. Finally, the algorithm is applied to a typical STSS constellation, and the simulation results show that the proposed method has better target-tracking performance than the nonclustering scheduling method.
