With the development of Web and wireless sensor networks
the appearance of big data has brought a great challenge to data query and process. The parallel Skyline computing issue of a moving query object under the MapReduce framework was studied. To solve the problem of load balance
a method based on angle partition was adopted. Then a filtering method was introduced to improve the efficiency. On the basis of those methods
a static Skyline algorithm and an event tracking algorithm named MR-Track were implemented respectively. Finally
many experiments were made to verify the effective and efficient of MR-Track algorithm.
