  6. 5. Energy Consumption in Location Sharing Protocols for Android Applications

    University essay from Programvara och system; Tekniska högskolan

    Author : Mihails Prihodko; [2012]
    Keywords : Message Queuing Telemetry Transport; location sharing; Android; energy consumption; 3G networks; UMTS WCDMA;

    Abstract : This thesis studies the Message Queue Telemetry Transport protocol (MQTT) as an application layer protocol in geographical location sharing applications using third generation cellular communication (3G). The MQTT protocol is compared in terms of energy efficiency and amount of data generated with the Hypertext Transfer Protocol (HTTP), which is currently used in typical location sharing applications.
