Sensor network node software including four nesC language components: sensor node directory and mode manager,
the query processor, memory management and network topology manager. The sensor node is responsible for
recording the attribute list for each node. The query processor is responsible for query processing, attributes using
sensor directory to store the information of sensor nodes can be obtained.
Wireless sensor network, they are rooted in the global information grid (global information grid, GIG). The global
information grid is connected by a global network, end to end a series of information capacity, the relevant
procedures and personnel, according to the researchers, all in the decision-making personnel and support staff
requirements to collection, processing, storage and management information, as is shown by equation (5).
