A Secure Real-time Concurrency Control Protocol Based on Optimistic
Computer Science, 2007Co-Authors: Xiao YingAbstract:Real-time database are usually needed in some safety-critical applications such as e-commerce, stock trading systems and military systems. In these applications, real-time database systems must simultaneously satisfy two requirements in guaranteeing data security and minimizing the missing deadlines ratio of transactions. However, these two requirements can conflict with each other and to achieve one requirement is to sacrifice the other. This paper presents a secure real-time concurrency Control Protocol based on optimistic method. The concurrency Control Protocol incorporates security constraints in a real-time optimistic concurrency Control Protocol,and can make a suitable tradeoff between security and real-time requirements according to the needs of applications. Performance tests show that the concurrency Control Protocol achieves data security without sacrificing real-time performance significantly.

Research of Concurrency Control Protocol in Mobile Computing Environments
Computer Engineering, 2005Co-Authors: Yuan Xiao-liAbstract:Multiple version optimistic concurrency Control Protocol (MVOCC) is presented. The Protocol can eliminate conflicts between read-only and update transactions and resolve data conflicts flexibly using dynamic adjustment of serialization order to avoid unnecessary transactions restarts. The results of experiment show that the Protocol performs better than optimistic concurrency Control Protocol (OCC) and timestamp order Protocol (TO).

An Efficient Secure Real-Time Concurrency Control Protocol
Wuhan University Journal of Natural Sciences, 2006Co-Authors: Xiao Yingyuan, Liu Yun-sheng, Chen XiangyangAbstract:Secure real-time databases must simultaneously satisfy two requirements in guaranteeing data security and minimizing the missing deadlines ratio of transactions. However, these two requirements can conflict with each other and achieve one requirement is to sacrifice the other. This paper presents a secure real-time concurrency Control Protocol based on optimistic method. The concurrency Control Protocol incorporates security constraints in a real-time optimistic concurrency Control Protocol and makes a suitable tradeoff between security and real-time requirements by introducing secure influence factor and real-time influence factor. The experimental results show the concurrency Control Protocol achieves data security without degrading real-time performance significantly.

Modified Timers in Improved Transmission Control Protocol Model
2015 Second International Conference on Advances in Computing and Communication Engineering, 2015Co-Authors: Ashwani Parashar, Swapnesh TaterhAbstract:Transmission Control Protocol is a key Protocol in TCP-IP Protocol Suite. Transmission Control Protocol is responsible for delivery of data to the application. The timers in Transmission Control Protocol ensures that the data is delivered and acknowledged to the nodes with in time. This paper describes modified Timers in Improved Transmission Control Protocol Model that ensure that the data is delivered efficiently among peers.

Improved transmission Control Protocol model
2014 International Conference on Control Instrumentation Communication and Computational Technologies (ICCICCT), 2014Co-Authors: Ashwani ParasharAbstract:Transmission Control Protocol is one of the key Protocol of Transport Layer in TCP/IP Protocols suite. While IP transmits data between individual computers on the Internet, TCP transfers data between actual applications running on the system. TCP provides connection oriented and reliable data stream. TCP achieves this reliability by assigning a sequence number to each segment it transmits and requiring a acknowledgment (ACK) from the receiving end. If the ACK is not received within the time-out interval, the data is retransmitted. This research paper describes improved Transmission Control Protocol model which transfers data efficiently among its peer.
