Technical issues and lessons learned in developing service-based mobile applications

Due to the resource limitations of mobile devices, it is difficult to run complex applications on the devices. To overcome the limitation, we adopt the concept of service-based mobile applications (SMAs) where some functionality is off loaded or provided as a service. Due to the complex nature of SMA architectures, it is challenging to design and implement efficient SMA. Hence, there is a demand for identifying technical issues and seeking their effective solutions. We do this by performing a commercial-level SMA system development, called Mobile Mate Service (MMS) which reveals a number of key features which are worth to explore. In this paper, we address essential technical issues and figure out solutions we applied and lessons learned.
