Optimization of majority protocol for controlling transactions concurrency in distributed databases by multi-agent systems

Abstract:   (4102 Views)
In this paper, we propose a new concurrency control algorithm based on multi-agent systems which is an extension of majority protocol. Then, we suggest a clustering approach to get better results in reliability, decreasing message passing and algorithm’s runtime. Here, we consider n different transactions working on non-conflict data items. Considering execution efficiency of some different transactions simultaneously is one of our algorithm features. For evaluating performance of the proposed algorithm we applied it using the MPICH2 mechanism.
