Abstract
Recently, a number of small yet powerful mobile computers have appeared on the market. Endowed with large disk capacity and network hardware, such systems are capable of holding large amounts of data, as well as of exchanging information with other hosts on a distributed system. These features suggest the need for the design and implementation of a distributed database system for mobile computers. Such mobile database systems present a host of technical challenges. One of them is dealing with the limited battery capacity of current mobile machines. We investigate the possibility of increasing the effective battery life of these computers by selecting energy-efficient query plans during query optimization. In this paper we review the capabilities of mobile computers and describe the power management issues in such systems. We examine the case of database systems on stand-alone mobile computers, and conclude that only a small modification is needed in standard query optimizers. However, ...
