Efficient object-oriented query optimisation in mobile computing environment
1998 (English)In: Journal of Research and Practice in Information Technology, ISSN 1443-458X, Vol. 30, no 2, p. 65-76Article in journal (Refereed) Published
Abstract [en]

Convergence of object-oriented technologies with advances in computer and communications technologies will lead to new paradigms and approaches to building object-based distributed systems, including mobile computing systems. Portable and mobile computers involved in mobile database query processing use battery power. These mobile hosts have severe battery energy problems and significant improvements in battery technology are not yet forthcoming. Portable computers rim on different energy consumption modes (normal and doze). This feature is used to save battery energy through flexible and efficient query optimisation. This paper discusses and proposes a two-dimensional energy-work 'query optimisation algorithm. The algorithm employs dynamic programming techniques and achieves a balance between saving energy consumption at mobile hosts and minimising total work for query processing in the whole database. A simulation of the algorithm is implemented and analysed
