Abstract: The working wireless sensor node is powered by its built-in battery.Therefore the effective control of energy consumption can greatly prolong the network life cycle and improve its utilization rate.In this paper,a clustering algorithm based on node priority and interesting data screening was proposed,which can be applied into environmental monitoring,etc.The node priority for being cluster head is calculated by the combination of the distance distribution of nodes and the remaining energy.Subsequently,the chosen cluster head will adopt the corresponding data screening method to handle the data obtained from the child nodes in each round.And the screened data will be sent to base station.The simulation results show that the proposed algorithm achieves better performance in the energy control and network life than others.

Key words: Priority weights,Data screening,Mean distance,Remaining energy,Network life cycle
