英文摘要：

A management model suitable for automatic switching of routing protocol of wireless sensor network is proposed according to present research situation. A concrete design scheme and implementation details of this model based on J2ME embedded programming and XML technology are addressed. This model is placed on the application layer of WSN architecture. Using engine classes programmed by JAVA to analyze XML-defined navigation function, the model implements automatic switching of routing protocol by user-defined method. That makes crosslayer management of application layer toward network layer possible. Simulation results indicate the benefits of the proposed model in terms of increasing efficiency and reducing delay from event source to sink.
