Abstract


Wireless sensor networks is a very hot topic today , but how the integration of wireless sensor networks and Internet networks , so as to share data in a wider range of information network development direction . Web Service technology as a new distributed computing technology , it has incomparable advantage of other technologies across Internet, cross-platform , distributed heterogeneous data integration provides strong support for the Internet . Based on the basis of the MICAz hardware system , using directed diffusion routing protocol organization real-time acquisition of wireless sensor networks . Duty-cycling strategy , applications in sensor nodes , Duty-cycling-V vehicle speed as the time window of the adjustment parameters can be dynamically adjusted to improve strategies to further reduce the energy consumption of the system . Design WSN-Internet gateway to achieve conversion of packets between wireless sensor networks and the Internet , and the establishment of a wireless sensor network connected to the Internet architecture . Network middleware and data persistence thought, a Web Service technology used in wireless sensor network data sharing distributed heterogeneous data integration framework . Access of the wireless sensor network is encapsulated into Web services , service registration and discovery , and the application can be found via HTTP , bind and invoke these services . By the definition of core services and ancillary services , sensor networks can be easily integrated into the application system . Finally, the simulation experiments in the theoretical and practical analysis of the feasibility and correctness . This paper to comply with the norms of component-based software development , information integrated magnetic sensor to achieve a seamless connection between the various systems , separate \The development of new systems based on Web Service to publish and discover services using UDDI to solve the problems of the sensor network information sharing mechanism based on SOAP Systems Interconnection , through the definition of services , publishing, discovery , binding , calls, etc. . And business is transparent to the user , wireless sensor networks can simultaneously access the Internet , low- overhead business to provide the advantages of convenience .
