Analyze the Wild Birds' Migration Tracks by MPI-Based Parallel Clustering Algorithm

Aiming at the avian influenza outbreak in Qinghai Lake area, the satellite tracking of migratory birds in Qinghai Lake is studied to analyze the relationship between bird migration, virus spread and ecological environment. These biological problems have been converted into computational studies in previous studies in which spatial clustering is the key factor. A bird migration data analysis system based on DBSCAN algorithm was designed in previous work, by which data can be systematically analyzed, and knowledge patterns are subsequently available for deep biological studies. As the GPS (Global Positioning System) raw data grows rapidly which is large scale with high complexity, DBSCAN takes long time (several minutes) to get the result. In this paper, parallel STING (statistical information grid) algorithm is designed and implemented based on MPI (message passing interface) for spatial clustering. By using parallel STING algorithm, it only takes several seconds to get the result.
