Sherlock: Monitoring sensor broadcasted data to optimize mobile environment

Rich-sensor Smartphones have made possible the recent birth of the mobile sensing research area as part of ubiquitous sensing which integrates other areas such as wireless sensor networks and web sensing. The object of sensing can be people-centered or environment-centered. The sensing domain can be home, urban, vehicular etc. Now there are barriers that limit the social acceptance of mobile sensing systems. Several technical barriers are phone energy savings and the variety of sensors and software for their management. In this article, we design and implement Sherlock technology, which captures a micro-environment through sensors and automatically records sensor hints and optimize the micro-environment of smartphones. We refer to such immediate surroundings as micro-environment, usually several to a dozen of centimeters, around a phone. The platform runs as a daemon process on a smartphone and provides finer-grained environment information to upper layer applications via programming interfaces. Sherlock is a unified framework covering the major cases of phone usage, placement, attitude, and interaction in practical uses with complicated user habits. The main objective is to save battery in mobile sensing systems and provides security.
