Context-aware Mobile Computing and Wireless Services

Context-aware computing involves the automatic tailoring of information and services based on the current context of the user of which the user’s location is a key component. The goal of the project is to enable various context and location aware services and to use context and location information to guide and achieve more efficient information distribution. So far we have developed a set of geographic routing schemes. Specifically, we have developed two self-adaptive geographic routing protocols that can provide reliable and efficient data delivery by adapting to the need of applications, the feature of traffic, and the change of network topology. To enable group communications, we have designed a self-contained robust and scalable position supported geographic multicast protocol. We are working on the development of efficient service provision framework, context-aware mobility models and services, as well supporting services over a collaborative set of wireless and wire-line devices.
