A layered architecture for ad hoc networks of mobile embedded systems

Ad hoc network does not have an infrastructure, all the nodes have the same functionality and they act not only as sender or destination of a message but also as routers. The lack of infrastructure and the equality of the nodes are not always desirable. This paper proposes a layered architecture for ad hoc networks. It consists in a three layers structure. The first layer consists in a server connected to Internet, the second layer is made by partially mobile nodes connected to Internet and the third layer is made by totally mobile nodes found in the coverage area of different partially mobile nodes. An application was developed on the proposed architecture.
