Because of the need of energy saving and also the presence of asymmetric features in a mobile computing environment, the conventional query processing for a distributed database cannot be directly applied to a mobile computing system. In this paper, we Þrst explore three asymmetric features of a mobile environment. Then, in light of these features, we devise query processing schemes. Performance of these query processing schemes is comparatively analyzed and sensitivity analysis on several parameters is conducted. © Springer-Verlag Berlin Heidelberg 2000.[SDGs]SDG7Cutting; Distributed computer systems; Distributed database systems; Energy conservation; Mobile computing; Multi agent systems; Sensitivity analysis; Cutting edge technology; Distributed database; Join processing; Mobile computers; Mobile computing environment; Mobile computing systems; Mobile environments; Query processingconference paper10.1007/10722620_25https://doi.org/10.1007/10722620_25
