Abstract

The launch and successful operation of the Mars Cube One (MarCO) CubeSat in May 2018 heralded a new era in solar system exploration and the setup of the first Interplanetary CubeSat Network (ICN). The success of this mission could give rise of an Interplanetary DTN–Based CubeSat network, in which the CubeSat Nanosatellite, as DTN custody node, plays the role of Data Mule to collect data from rovers on a planet such as Mars. In order to maximize the contact volume which is the amount of transmitting data from rovers to the CubeSat during its pass over their service zone, we will need to design an efficient MAC protocol. This research focuses on the simulation and evaluation of the performance of the Slotted AlohaCA MAC Protocol on the planet Mars compared to Earth taking into account the different properties between the two planets, such as radius, mass and speed of rotation of the Nanosatellite in its orbital at the same altitude. We have conducted many simulations using the NS2 simulator that takes into consideration the spatial dynamic behavior of the Nanosatellite, which is dependent on motion of the Nanosatellite in its orbit. Three appropriate performance measures are evaluated: Throughput, stability and power consumption. The obtained simulation results on the planet Mars show an improvement on performance of the Slotted AlohaCA on the planet Mars compared to Earth.

火星上增强型开槽AlohaCA协议的性能评价

2018年5月，火星立方体一号(MarCO)立方体卫星的发射和成功运行，标志着太阳系探测的新时代和首个行星际立方体卫星网络(ICN)的建立。该任务的成功可能会产生一个基于DTN的行星际立方体卫星网络，其中立方体卫星纳米卫星作为DTN保管节点，扮演数据骡子的角色，从火星等行星上的漫游者收集数据。为了最大限度地提高接触量，即在漫游车经过服务区域时向立方体卫星传输数据的量，我们需要设计一个有效的MAC协议。考虑到纳米卫星在相同高度的轨道上的半径、质量和自转速度等不同特性，重点对开槽AlohaCA MAC协议在火星和地球上的性能进行了仿真和评估。我们使用NS2模拟器进行了许多模拟，该模拟器考虑了纳米卫星的空间动力学行为，这取决于纳米卫星在其轨道上的运动。评估了三个适当的性能指标:吞吐量、稳定性和功耗。在火星上的仿真结果表明，槽式AlohaCA在火星上的性能比在地球上有所提高。
