摘要:Aiming at the existing problems such as high shard collision rate and so on of Smart algorithm in the data aggregation of the wireless sensor network, this paper puts forward the improved Smart data aggregation algorithm. The algorithm in this paper adds optimization factors from five aspects, and the addition of the various optimization factors makes the accuracy be improved, the communication traffic of the scheme also be effectively reduced at the same time, which indirectly prolongs the survival time of the network. The experimental results show that the improved algorithm of this paper can improve the accuracy and security of the data aggregation.
