Development of Routing Application of SCA-Based Software Defined Radio

Software communications architecture (SCA) has become the standard framework followed by the current developing software defined radios (SDR) all over the world. So it is significant for us to develop some essential applications in such an SCA-based SDR. In this paper, we propose an implementation scheme of routing application based on SCA. First, the framework and functions of SCA are introduced briefly. In the following, routing technology is discussed in such a software radio network with multi-layer dynamic topology. Based on SCA, the system architecture on which the routing application depends is presented. We put emphasis on the design of routing components and application program interface (API). Using a sequence diagram, the interaction among routing selection component, adaptive channel selection component and MAC components, is shown clearly
