To improve the real-time data transmission rate of unmanned vehicle ad hoc network and improve the throughput of unmanned vehicle network, a cooperative resource allocation algorithm for unmanned vehicle network link scheduling is proposed. Firstly, a 2-H cooperative communication system is constructed. The value function is used to describe the relationship between the link rate and the allocated resource unit. The maximum throughput equation of the unmanned vehicle is further proposed. Then, to allocate the communication resources reasonably, the link rate is dispatched based on multi-select knapsack problem, and the optimal value of the number of unmanned vehicle nodes is solved by exhaustive search method. Experimental results show that, compared with the vehicle network based on the distributed sensing and clustering and the optimization of the vehicle network based on the channel transmission model, the proposed algorithm improves the link speed by 8.7% and 7.4% respectively, and the total network throughput is improved respectively 10.6% and 12.8%. The proposed algorithm can better meet the requirements of data transmission rate of unmanned vehicle networks.
