Grouping control strategy and software realization method for sensor nodes in wireless sensor networks（WSNs）is introduced.In order to solve the communication problems and practical requirement of distributed monitoring

grouping control strategy

modularization control process

and failure disposal method are built up.These techniques guarantee the independence of multi-node monitoring

synchronicity related nodes acquisition and reliability of data transmission.In realization of program

software architecture

which is composed of communication interface layer

message delivering layer and strategy control layer are set up.Remote control software for WSNs is realized and test experiment on multi-sensor nodes control the reliability of data transmission is carried out.
