Improved algorithm of reducing delay in data aggregation
减少时延的数据融合改进算法

Through studying the algorithm FHF of constructing the data aggregation tree, it is found that when the distant nodes are from the sink node transmit data to the sink node, the delay is longer. To reduce the transmission delay of abnormal data, particularly in large data packets occasions, the method of keeping a detection bit in the MAC layer was used to deal with unexpected events. Simulation results show that this method can reduce the delay of abnormal data transmission, and the emergency measures are relatively good.
