Abstract:
To offload the traffic brought by the explosion of mobile video traffic on present cellular networks, unmanned aerial vehicle (UAV) with moving ability is introduced, where UAV can fly to the cell edge to serve ground users and help offload the video traffic. In this paper, we consider the joint optimization of trajectory design and transmission rate allocation for reliable video streaming in aerial vehicle networks, and formulate the problem with a non-convex programming. By using the bisection method over the relationship between transmission rate and outage probability, a sub-optimal solution is proposed by using success optimization methods, and the solution can be guaranteed to be a local optimal solution. Simulation results show that the proposed scheme can achieve significant gains in terms of transmission outage probability, which is an important performance metric for reliable transmission.
