The Mobile Computing Group investigates different aspects of wireless and mobile communications. The group has a strong focus on mobile middleware and service platforms.Recent research of the group pertains to mobile cloud computing, data and computation offloading, and energy modeling and optimization. The group was founded by the late Professor Kimmo Raatikainen.
Our vision is that each layer of the networking stack must be aware of the environment, and the whole communication stack needs to be optimized and made adaptive. A key challenge is how to distribute service functionality and logic in the distributed environment. The aim of our work is to enable efficient, secure, always-on, and reliable connectivity irrespective of the access network and terminal device. Moreover, service access and usage must be personalized and adapted to the current operating context.
Our central research items include synchronous and asynchronous middleware communications, publish/subscribe, data synchronization, context-aware systems, and more recently peer-to-peer content dissemination and delivery.
