Data-Driven Implementation of Protocol Handling for Supporting Ad Hoc and Ubiquitous Networking Environment

Pervasive networking environment as social infrastructure has been going to become a reality, especially through the recent considerable progress of semiconductor technology. Considering the case where next generation of pervasive networking is realized over ad hoc network suitable for emergency and some tentative event, a project named “Ad hoc and Ubiquitous Communication Environment” has begun. It is very important to implement effective protocol handling and routing process in Ad hoc and ubiquitous networking environment especially. This paper describes the effectiveness of an implementation of protocol handling using networking-oriented data-driven processors CUE (Coordinating User’s requirements and Engineering constraints). In Ad hoc network, it is necessary to realize not only network protocol but also routing protocol such as DSR(dynamic source routing) protocol. Firstly, this paper discusses datadriven implementation of protocol handling on CUE networking board. Then this paper describes architecture of CUE-v2 which is available version in CUE processors. Furthermore, this paper proposes protocol handling off-loader which is implemented on the CUE-v2 networking board to minimize overheads in protocol handling. This paper finally discusses effectiveness of protocol handling off-loader using CUE processor system. it describes that client such as PC uses performance to process application which are video/audio processing without overhead in network communication.
