无线传感器网络应用中的实例，需用matlab工具箱。-* Major performance improvements when using the network blocks. The simulation

　time is now linear rather than exponential in the simulated time. [The poor

　performance in previous versions was due to Matlab s memory management.]

* Two new Simulink blocks added, making it easier to develop networked

　applications. The two blocks makes it possible to send and receive network

　messages without using kernel blocks and code functions. A related new
