摘    要:无人机Ad hoc网络是一种拓扑变化频繁的特殊能量受限网络,为平衡网络中各节点的通信能耗,降低传输总能耗,从网络分层优化的角度入手,提出了一种综合考量物理层能源消耗率与网络层跳数最小化的预期寿命路由度量,保证跳数较少的前提下,分组沿预期寿命较大的路径传输,并给出了改进路由算法在NS-3中的具体实现。仿真结果显示,引入新度量后,网络的总能耗相比经典协议降低了12%,各节点剩余能量分布方差降低了17%,较长仿真时间内节点存活率提升了18%。结果表明改进协议均衡了无人机网络中各节点的能耗分布,降低了网络的总能耗,在一定程度上降低了节点死亡率,延长了网络寿命。

Flying Ad hoc networks's cross-layer energy optimization routing protocol based on NS-3
Authors:CHEN Buliao  FENG Man  MA Haibo
Abstract:The flying Ad hoc network is a special kind of energy-constrained network with frequent topology changes. In order to balance the communication energy consumption of network nodes and reduce total energy consumption of transmission, this paper begins with the perspective of network layering optimization, and then proposes a comprehensive consideration between the energy consumption rate of the physical layer and the minimum network hop count, aiming at the characteristics of FANETs. Under the premise of ensuring fewer hops, packets are transmitted along the path with the longest life expectancy.The concrete implement uses NS-3. As simulation results show, after the introduction of the new routing metric, the total energy consumption of the network is reduced by 12%, the variance of the remaining energy distribution of each node is reduced by 17%, and the survival rate of nodes is increased by 18% during a long simulation time.The results indicate that the improved protocol equalizes the energy consumption distribution of each node in FANETs, and reduces the total energy consumption of the network. Meanwhile, the refactoring protocol reduces the node mortality to a certain extent, and prolongs the whole network lifetime.
