摘　　要：航空自组网是应用于航空通信领域的移动Ad Hoc网络,其采用动态组网等技术将航空飞行器互联互通。运用适当的分簇算法,将飞行器合理地分组,可以有效地降低航空自组网数据传输的时延,减少数据传输的能耗,提高网络的寿命。对一种具有时延意识的分簇算法DACC进行了修改,在簇头选择的过程中加入了平均能耗的思想,提出了节能的改进算法DACC-EE,并与传统的分簇算法LEACH进行了对比。仿真结果显示,DACC-EE并没有改变DACC的时延优势,且网络寿命显著高于DACC和LEACH。Aeronautical Ad Hoc network（AANET） is the application of Ad Hoc network in the field of aviation communication.AANET uses dynamic networking technologies to construct the network topology.Using appropriate clustering algorithm to make aircrafts into groups is an effective way to reduce the latency in data transmission.And it can prolong the network lifetime of AANET.This paper makes improvement to a delay-aware cluster construction algorithm,DACC.We add averaging energy consumption strategy in the cluster head selection and propose an improved algorithm,DACC-EE,to prolong the network lifetime.Simulation results show that DACC-EE doesn＇t change the delay efficient features of DACC,and the performance of network lifetime of DACC-EE is much better than DACC and LEACH.
