  2. Some suggested Topics • Dynamic web service composition framework (DWSC). • Web Services in Mobile Internet (WSMI). • Web Service Security(WSS).

  3. DWSC • What is web service composition? • Composing Autonomous Web Services to achieve a new functionality!! • Advantages of WSC • Re-Usability • Reduce development time for new applications.

  4. DWSC • Future Requirements for applications in the web. • Application/software need to be adaptive. • Context aware • User centric • Environment centric. Need for a runtime selection of web services!!

  5. Suggested Solutions • Not a web service centric architecture!! • Two layer architecture • Business logic layer. • Decision/dynamic composition layer. • ?????
