Energy-Aware Keyword Search on Mobile Phones

With the explosive growth of communication technologies, modern mobile phones become more powerful than ever. Unfortunately, the battery lifetime of mobile phones is still limited, and energy awareness is a priority of designing applications on mobile phones. To demonstrate the energy awareness on mobile phones, the authors propose a new approach for full-text keyword searches to retrieve content matching input keywords. The proposed approach generalizes the two solutions that answer the keyword searches either locally by mobile phones themselves or remotely by power servers when the keywords are offloaded to such servers. Instead, for low energy, they propose to split the keywords in a search into two subsets, such that one subset is processed by the mobile phone and another by the remote server.
