Real-time Concurrency Control Mechanisms in Wireless Mobile Distributed Environments

Owing to the unique characteristics of mobile real-time environments,traditional serializability is too strong.This paper presents the use of the relaxed serializability as correctness criterion.After it formally defines and analyzes a new serializability,corresponding concurrency control protocol based on this criterion is outlined for real-time mobile environments.Finally,experimental results show that the proposed protocol helps more mobile real-time transactions to meet their deadlines while database consistency is maintained.
