Typically,weapon data link is used for the aspects of the information sharing,command guidance,task coordination and allocation. In order to improve the weapon link anti-jamming and anti-interception ability,we control the antenna scanning and aiming state by the antenna control module. The program can satisfy the operational requirements of the intra-flight data transmission and support multiple weapons communication at the same time by analyzing the feasibility and delay based on OPNET network simulation software.

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 delayaware 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.
