Performance Evaluation on Several Cautious Schedulers for Database Concurrency Control
TL;DR: By means of simulation studies, this paper evaluates the performance of three cautious schedulers: (1) cautious two-phase locking scheduling, (2) exclusive preclaimed two- PhaseLock scheduling, and (3) cautious conflict serializable scheduling.
Proceedings ArticleDOI
A novel secure localization scheme against collaborative collusion in wireless sensor networks
TL;DR: A new collusion attack model called Collaborative Collusion Attack Model (CCAM) is introduced and a novel scheme called Two-Step Format Detection (TSFD) that is well suited to WSN which is a resource constrained environment and has reasonable and acceptable communication cost and algorithm complexity.
Proceedings ArticleDOI
An Examination of Sensor Data Collection Method for Spatial Interpolation on Hierarchical Delaunay Overlay Network
TL;DR: A sensor data collection method for peer-to-peer sensor network to realize spatial interpolation of sensor data, assuming hierarchical Delaunay overlay network (HDOV) to collect sensor data uniformly.
Journal ArticleDOI
A Communication Protocol for Sensor Database Construction by Rounding Sink
Tomoki Yoshihisa,Shojiro Nishio +1 more
TL;DR: This paper proposed a data collection protocol considering the data amount that each sensor has and confirmed that the proposed protocol can give fairness to the amount of collected data.
Proceedings ArticleDOI
Main memory database for supporting database migration
TL;DR: This paper discusses the physical database structure which realizes high speed database migration, and proposes the recovery methods for migratory main memory databases.
