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. |
