| Abstract: | Nowadays, a lot of mobile devices exist that are characterized by their high processing power and low costs. Next to this, they have the ability to connect to the Internet using wireless communication technologies like GPRS, UMTS or WLAN. These advances in mobile device capabilities and communication technologies have enabled new mobile applications by which services are deployed on the mobile device which are available to users on the Internet. This is called nomadic mobile service provisioning and has been successfully used in the remote healthcare monitoring domain. Nomadic mobile services are characterized by the limitations of their mobile devices and their wireless communication technology. The ASNA chair developed a Mobile Service Platform (MSP) to deal with these issues. This thesis focuses on performance measurements of MSP, using a WLAN as MSP transport system, and how the location of a mobile device can affect this performance. Integrating these performance measurements within applications enables pro-active adoptation of an application. To accomplish this goal a software framework has been developed to retrieve time and location information via GPS and an evaluation system is build to evaluate the MSP performance. The evaluation system is using MSP as a service infrastructure with example workload parameters from healthcare applications which have, in other circumstances, already used MSP. My research has shown that the bottleneck in MSP is not the underlying communication technology (WLAN) but the protocol entities which are used in MSP. The maximum goodput that is reached in the experiments is less than 5% of the (theoretical) WLAN maximum throughput. Measurements performed at multiple locations pointed out that the MSP goodput can differ more than 5%. |
