无人机编队信息传输能耗平衡协同设计

Balance-Energy Consumption Cooperative Design for UAV Formation Information Transmission

针对无人机编队自组织网络拓扑结构的动态特性,导致编队中的无人机信息传输能量消耗不均匀,影响侦查任务的高效实施。提出了一种无人机编队信息传输能耗平衡协同设计方法。上述方法采用协同中继下的能量消耗模型,各无人机通过编队间的能量感知获得自身能量剩余程度,合理选择信息传输方式:通过邻近的其它无人机中继后下传给地面基站或者在能量消耗较少的情况下直接下传给地面基站。仿真结果表明,就地面基站收集信息的次数因素而言,协同中继算法能比分簇算法提高约22%左右,证明改进方法可以有效节省能量,延长了无人机编队的侦察时间。

Due to dynamic topology of unmanned aerial vehicle （UAV） formation mobile ad hoc network, the en- ergy consumption is not unbalanced for UAV formation information transmission, which will affect the effective imple- mentation of reconnaissance. A cooperative design method of balance - energy consumption for UAV formation infor- mation transmission is proposed based on cooperative relaying radio energy consumption model. The data transmission method is reasonably chosen according to remaining energy of themselves. The other nearby relay UAVs download da- ta are used to ground base station to achieve fair energy consumption or transmitting data directly without relay in case of less energy consumption. The simulations show that the cooperative relaying （CR） is approximately twenty - two percent more than clustering algorithm as far as the number of data collection rounds by ground base station respect. The energy- aware CR algorithm demonstrates that energy consumption is reduced and the reconnaissance time of UAV formation is prolonged.
