Communication Mechanism & Correlation Steps of Integrating of WSN and Grid

Uniting wireless sensor networks (WSN) and grid computer to establish a grid distributed control system, which enables the system user to share the gathering data, and implement operation and control WSN through the middleware of grid. Ultimately to realize the macrozonality scope monitoring and the target tracking function. This paper discusses three essential technical questions about WSN connecting grid and regarding as GDCS shared resource: first, proposes two connections pattern based on static data collection or dynamic data collection, second, establishs the event driven communication model and data transmission mechanism based on different connection pattern, and third, elaborates the correlation algorithm and connecting steps by two examples. The examples proved it´s effective that we proposed the correspondence mechanism and the correlation algorithm Finally proposes our conclusion.
