Mobile Location Sharing: An Energy Consumption Study

The use of a mobile device's battery for frequent transmissions of position data in a location sharing application can be more expensive than the location retrieval itself. This is in part due to energy-agnostic application development and in part dependent on choice of protocols. This paper studies the lightweight Message Queuing Telemetry Transport protocol (MQTT) as an application layer protocol on top of the third generation cellular communication. The energy efficiency and amount of data generated by the public/subscribe MQTT protocol is experimentally compared against the Hyper Text Transfer Protocol (HTTP), which is currently used in typical location sharing applications.
