Defining a New Cloud Service for Location

Watching that in lots of sensing situations, the place information could be publish-processed once the information is submitted to some server, we design Cloud-Offloaded Gps navigation (CO-Gps navigation) solution that enables a sensing device to strongly duty-cycle its Gps navigation receiver and log sufficient raw Gps navigation signal for publish-processing. Location is really a fundamental service for traveling with a laptop. Typical Gps navigation receivers, although broadly readily available for navigation reasons, may consume an excessive amount of energy to become helpful for a lot of programs. Localization is really a fundamental service in mobility. In outside programs for example wildlife monitoring, participatory ecological sensing, and private overall health programs, Gps navigation is easily the most common location sensor. Leveraging openly available information for example GNSS satellite ephemeris as well as an Earth elevation database, a cloud service can derive top quality Gps navigation locations from the couple of milliseconds of raw data. Using our style of a transportable sensing device platform known as CLEON, we assess the precision and efficiency from the solution. In comparison to greater than thirty seconds of heavy signal processing on standalone Gps navigation receivers, we are able to achieve three orders of magnitude lower energy consumption per location marking.
