Large scale deployment of sensor nodes in wireless sensor network monitoring system, the WSN usually have
higher node redundancy, network link redundancy and data redundancy provides strong fault tolerant ability for the
whole system. The paper proposes design and implementation of monitoring information system based on wireless
sensor network technology. In addition, it is with the help of individual nodes with mobility in sensor nodes to
adjust the network topology. Features include query optimization, receiving, verification request, receive the query
management and query result, send control commands, connected with the wireless sensor network, database and
user interface etc.
