**5. Conclusion**

The chapter presents a strategy for networking real-time applications development--based on Blackfin microcomputers family, VDK operating kernel and LWIP stack protocol--and evaluates the performance of the lightweight TCP/IP protocol stack for embedded systems. Its applications reside in sensor networks in which the sensors may be connected directly to the Internet. This strategy may be used for various complex applications such digital signal processing in sensor network. The overall performance is similar to the performance of the implementation of the TCP/IP protocol stack in PCs. The connection time and response time are slower in the LWIP implementation, comparing with typical TCP/IP implementation, but they are acceptable. A real-time implementation of network applications, such as voice- over IP system, is exemplified, using a dual core microcomputer and a practical approach to achieve a real-time functioning is provided. Future work will investigate the real-time functionality of presented strategy in multimedia applications.
