The deployment of 3G networks (UMTS, CDMA 2000,     PackCable) along with the related service architectures has just started. Research has now shifted to post 3G networks. However, very little is being done on the related service architectures. This proposed research program is devoted to the service architectures for 4G. In the proposal we use the world wireless research forum (WWRF) definition of 4G (i.e. co-existing/co-operating legacy and new networks. On the one hand we use 3G networks as use cases for legacy networks. On the other hand we use mobile ad hoc networks (MANETs) and wireless sensor networks (WSNs) as use cases for new networks. Architectures for creating, deploying, using and withdrawing end-user applications/services in stand alone MANETs, stand alone WSNs, and integrated 3G/MANETs/WSNs/ are investigated. Functional entities, algorithms and interfaces are proposed and validated. Mathematical analysis, prototyping, and simulation are used for validation and performance evaluation. The architectures rely on a panoply of technologies such as context awareness, clustering, overlay networks, peer to peer and mobile agents. These technologies are exploited to the fullest possible extent. Furthermore, whenever necessary, we investigate how to extend them.
