Abstract


Reducing energy consumption for handhelds (PDAs) is still a major challenge. In this paper, we investigate the application-level models for energy-efficient Wi-Fi communication, using IEEE 802.11b. The basic idea is to conserve energy by modelling energy awareness depending on the device usage modes. We describe an infrastructure for the modelling of energy awareness, the energy evaluation and measurement strategy and the methodology, which is supported by the experimental results we carried out. The application-aware strategies can reduce the energy consumption in communication when downloading large files to PDAs, however, the largest portion of energy consumption falls on the unpredictable state of wireless communication. We suggest the algorithm to deal with the problem. Ill. 5, bibl. 10 (in English; abstracts in English, Russian and Lithuanian).
