1. A Traffic Flow Theory Aided Physical Measurement-Based Sybil Nodes Detection Mechanism in Vehicular Ad-hoc Networks

Dongxu Jin, JooSeok Song
Pages: 69 - 78
In Vehicular Ad-hoc Networks, security is a important issue. In the past years, several approaches have been proposed for solving Sybil attack. In this paper a novel scheme to detect the Sybil nodes is presented. The proposed scheme utilizes unmodifiable physical measurements of beacon messages. To increase...

2. Optimal Number of Clusters for Fast Similarity Search Considering Transformations of Time Varying Data

Toshiichiro Iwashita, Teruhisa Hochin, Hiroki Nomiya
Pages: 79 - 88
This paper proposes a method of determining the optimal number of clusters dividing the multiple transformations for the purpose of the efficient processing of query against the results of applying the transformations to time series. In this paper, the moving average is used as a transformation for simplicity....

3. Parallel Indexing Scheme for Data Intensive Applications

Kenta Funaki, Teruhisa Hochin, Hiroki Nomiya, Hideya Nakanishi
Pages: 89 - 98
This paper proposes a parallel indexing scheme of a large amount of data in order to resolve the issues about time limitation. Three kinds of computing-nodes are introduced. These are reception-nodes, representative-nodes, and normal-nodes. A reception-node receives data for insertion. A representative-node...

4. Evaluation of A Secure Live Migration of Virtual Machines Using IPsec Implementation

Norshazrul Azman bin Sulaiman, Hideo Masuda
Pages: 99 - 108
Live migration enables administrators to perform online maintenance on host and virtual machines without interrupted service during fault occurrences. While migrating VMs between physical servers of different data centers over the network is considered, security is essential for securing the migration...

5. Integrated Usage of Heterogeneous Databases for Novice Users

Ayano Terakawa, Teruhisa Hochin, Hiroki Nomiya
Pages: 109 - 118
This paper proposes the system enabling users to use heterogeneous databases in an integrated manner without any conversion and servers. In order to treat a variety of sources in a unified manner, this system is realized by using Java Database Connectivity (JDBC) in accessing databases on the user’s...

6. Incremental Data Migration for Multi-Database Systems Based on MySQL with SPIDER Storage Engines

Naoyuki Miyamoto, Ken Higuchi, Tatsuo Tsuji
Pages: 119 - 127
In this paper, an incremental data migration technique is evaluated in the multi-database system based on MySQL with SPIDER storage engine and the improvement of the turn-around times of other operations is proved in this systems. In this method, a large data migration is divided into small data migrations...

7. Scenarios for An RFID Tag Ownership Transfer Protocol for A Closed Loop System

Gaith K.D. Al., Biplob Rakshit Ray, Morshed Chowdhury
Pages: 128 - 136
In RFID system a tag is attached to an object which might own by a number of owners during its life time. This requires the RFID system to transfer ownership of the tag to its new owner. The ownership transfer has to protect privacy of current and new owner. Many ownership tag ownership transfer exists...
