This paper presents a simulation analysis of the impact of mobility on concurrent transaction processing over a mixture of mobile and fixed transactions. Our results show that the traditional concurrency protocol yield low throughput in mixture mobile and fixed environments due to the fact that traditional protocol cannot discriminate implications of restart of both types of transactions. As a result, the number of restarts can be unbounded and the ongoing mobile transactions that share the same wireless resources will be affected. We investigate adaptive adjustment the serialization order of transactions such that a conflict resolution should be give more rooms for mobile transaction. We show that by effectively capitalizing this information, the number of unnecessary restarts can be highly reduced. Based on the simulation analysis, we show that this protocol provide a significant performance gain in mixed transaction environments.
