Abstract [en]

This bachelor thesis will explore how two traffic shaping mechanisms can help preserve battery power while retaining a certain Quality of Service (QoS) in an Android based application developed for crisis management. The implemented user-space mechanisms will delay all elastic data requests in order to reduce the number of times the 3G transmission radio enters high power states. This lowers the QoS but extends the user equipment's battery life. The thesis will show that a shaping mechanism has the capability to reduce radio energy usage by up to 50% for the given Android application at the cost of added transmission delays by up to 134 seconds for background traffic. The study also presents two policies that help the application adapt to the current battery level and lower the QoS accordingly, namely one that has a lenient savings effect and one that has an aggressive savings effect.
