This report describes PlaceMe, a client side, mobile application built on the Android platform that provides personal location-based services such as location reminders, bookmarking, mapping and search nearby. The reminder system allows creating location based reminders, and alerts the user what he needs to do, when he is in the right place to do them. Bookmarking allows the user to virtually “save” places of interest while he is on the move and obtain driving directions. Mapping enables the user to visualize his relative geographic location in real time, and map the location reminders and bookmarks. Finally, search nearby exploits Google’s powerful local search engine to allow finding and bookmarking nearby places such as gas stations, restaurants, etc, and retrieving map-based directions. We first discuss the requirements and use-cases for PlaceMe, followed an introduction to the Android software stack. Next, we describe our design architecture, implementation model, test strategy and key performance enhancements. Then, we evaluate and compare the performance of the Android platform across a set of standard micro-benchmarks. Finally, we conclude with a discussion of future development ideas and present our thoughts on prospects of app-based mobile computing. / text
