    3  == Overview ==  
     3VTCROSS is a research project at [http://wireless.vt.edu/ Wireless@VT] that is developing an open source Cognitive Radio architecture.  The objective of the design is to develop a distributed & modular system that provides portability and interoperability between components developed in different programming languages, across different SDR and hardware platforms.  By doing so, we hope to enable more flexible and streamlined development for cognitive radio systems.  Users of VTCROSS can focus entirely on one aspect of the cognitive radio radio without developing or modifying components that have no direct relevance to their specific focus of research.

    5 An effort is currently beginning at [http://wireless.vt.edu/ Wireless @ VT] to develop an open source Cognitive Radio architecture.  The objective of the design is to develop a modular system that provides portability and interoperability between components developed using different programming languages.  Not only will this allow for flexible development for the cognitive radio system, but will allow developers to focus entirely on the component of choice and to not have to worry about developing or modifying components that have no relevance to their specific focus of research.

    15 === Intercomponent Communication === 
    16 The CROSS is a modular cognitive radio system framework that utilizes socket connections for the inter-component communication method.  Utilizing a socket connection for component communication allows the system components to be developed in a language independent manner.  Even though the Cognitive Radio Shell library and API will be implemented in C++, the external modules such as the Cognitive Engine, Service Management Layer, and Policy Engine can be implemented in any language that supports a TCP/IP socket interface.

    28 In addition to the feature of language independent development, the natural benefit of a TCP/IP socket interface is the ability to operate modules remotely.  The Cognitive Radio Shell is located local to the radio hardware, however, the Cognitive Engine or Policy Engine can be located remotely on hardware more appropriate for complex optimization or for distributed policy decision making.  Clearly, the remote operation depends upon the timing critical nature of the return of the optimization results.  In no way does the TCP/IP socket communication limit the Cognitive Radio System to only remote modules, in fact local socket connections require little overhead and provide for a flexible method of connecting these major Cognitive Radio System components.
