In this way, the B s -tree keeps good and smooth overall performance despite the change of the workload. It can be seen that in almost all cases, the B s -tree outperforms the TPR*-tree and the Bx -tree in overall performance. ϯϬ Ϯϱ ϮϬ džͲƚƌĞĞ ƐͲƚƌĞĞ dWZΎͲƚƌĞĞ ϭϱ ϭϬ ϱ Ϭ ϭ͗ϭϬϬϬ ϭ͗ϭϬϬ ϭ͗ϭϬ ϭ͗ϭ ϭϬ͗ϭ ϭϬϬ͗ϭ ηŽĨYƵĞƌŝĞƐ͗ηŽĨhƉĚĂƚĞƐ ;ďͿKǀĞƌĂůůWhdŝŵĞ Fig. 6. 3 Self-tuning Performance The above experiments show that the Bs -tree has good performance when it reaches the steady states. However, if the performance degrades markedly when the B s -tree is in the 14 N.

2 Self-tuning Framework From the above analysis, we find that the update and query performance of the B s -tree can be tuned by the update parameter α and the query parameter β. However, α and β can not be changed arbitrarily. We should guarantee the correctness of the queries. Theorem 1. As long as β is no less than all α of all moving objects, the query correctness of the Bs -tree can be guaranteed. That is, given a query, the B s -tree can find all moving objects which satisfy the query in their t per s.

T otal T RJ = k else remove C from group of clusters Translate representative trajectories into output format Fig. 3. An Outline of Clustering-based Anonymization Algorithm Definition 4. (Strict k-anonymity over trajectories): Let T rj be a trajectory. We say T rj satisfies strict k-anonymity if Support(Trj) is no less than k. 2 Finding Candidate Clusters In this subsection, we present how to find a candidate cluster for a new trajectory during the clustering-based anonymization. The first step is to check whether a new trajectory can be absorbed by an existing cluster according to the distance metric.
