Abstract: Due to consume too much energy of the sensor nodes for the LEACH,HEED and TEEN protocol in the process of transmitting data in the WSNs,the algorithm of compressing relevant data is proposed,and the expression of selecting cluster head and data compressing is derived.Theoretical analysis and simulation results show that compared with LEACH,HEED and EABGC,the proposed algorithm can avoid transmitting relevant data repeatedly and reduce the node energy consumption effectively.Using the proposed algorithm,more nodes can be survived in the same lifetime and it can keep a low energy consumption of the nodes,so the lifetime of WSNs is prolonged.
