Computing Science. Optimistic Concurrency Control for Energy Efficiency in the Wireless Environment, CS-TR-1411.

摘要

The ubiquity of smart portable devices has led to concurrency control for the mobile network becoming an area of growing concern. Conventional optimistic concurrency control techniques require retries of failed or disputed transactions, which place additional drain on the energy consumption of both the network and the smart device. We present a Distributed Later Validation Earlier Write Optimistic Concurrency Control (DLVEW) algorithm to efficiently handle transactions running on the server side without disturbing transactions running on clients. Our simulation shows an increase in throughput and reduction in both the response time and the number of missed deadlines of transactions. The corresponding reduction in contentious transactions needing to be restarted leads to a lower power cost for the network as a whole.
