Using content-based addresses as a programming construct for scenario specific routing and multicasting

In this paper we extend the notion of contentbased addressing with a programmable forwarding scheme which yields a powerful programming construct for expressing scenario specific routing and multicasting. We demonstrate the expressive power of this construct through examples of over-the-air code dissemination and composition of heterogeneous services and communication between them. Furthermore, we show an efficient implementation and indicate how the underlying forwarding mechanism can be replaced to further enhance the expressivity and efficiency1. The realization of the content-based addresses does not require periodic address announcements and construction of routing tables and can therefore be applied in highly dynamic networks at low cost.
