This research project proposes to develop a transaction management technique for a mobile multidatabase management system that takes energy restriction, transaction real-time constraints, and ad-hoc networks into consideration. This technique is aimed at reducing the overall energy consumption and providing a balance in individual mobile host (MH) energy consumption, while at the same time reducing the number of transactions that must be aborted due to deadline violations. It considers both firm real-time and soft real-time transactions, and three modes that an MH can be in: active, doze, and sleep. It treats time as the most important factor in handling firm transactions while energy as the most important factor in handling soft transactions. It uses this principle to locate MHs, schedule transactions, and commit/abort transactions. It handles disconnection and migration by introducing a suspended state into global transactions to ensure that transactions of mobile users whose status is unknown will not be aborted until they obstruct the execution of other transactions. A prototype will be developed to evaluate the performance of the proposed technique for real-life applications and to provide guidelines to assist both users and designers.

本研究计划提出一种针对移动多数据库管理系统的事务管理技术，该系统考虑了能量限制、事务实时性限制和自组织网络。该技术旨在降低总体能耗，并在单个移动主机（MH）能耗中提供平衡，同时减少由于违反截止日期而必须中止的事务数量。它考虑了硬实时和软实时事务，以及MH可以处于的三种模式：活动、瞌睡和睡眠。在处理硬交易时，时间是最重要的因素；在处理软交易时，精力是最重要的因素。它使用这个原则来定位mh、调度事务以及提交/中止事务。它通过在全局事务中引入暂停状态来处理断开连接和迁移，以确保状态未知的移动用户的事务不会被中止，直到它们阻碍其他事务的执行。将开发一个原型，以评估所建议的技术在实际应用中的性能，并提供指导方针，以协助用户和设计者。
