摘要

我们解决了在类铱低轨道星座中延长卫星使用寿命的路由问题。低轨道星座的卫星有超过30%的时间处于地球本影之下,在此期间它们是由电池供电的。当电池通过太阳能充电时,它们在日食期间达到的放电深度会显著影响它们的使用寿命,进而影响卫星本身的使用寿命。对于为铱星提供动力的那种电池来说,放电深度增加15%实际上会使它们的使用寿命缩短一半。我们提出了两个新的路由指标- LASER和SLIM -试图在低轨道卫星星座的性能和电池放电深度之间取得平衡。我们的基本方法是利用卫星的确定性运动来支持路由流量,而不是暴露在阳光下的卫星,而不是黯然失色的卫星,从而降低电池的平均放电深度——所有这些都不会对网络性能产生不利影响。仿真结果表明,LASER和SLIM分别可以减少约11%和16%的放电深度,从而使卫星电池寿命延长100%。这是通过在端到端延迟方面付出很少的代价来实现的。

On routing for extending satellite service life in LEO satellite networks
We address the problem of routing for extending the service life of satellites in Iridium-like LEO constellations. Satellites in LEO constellations can spend over 30% of their time under the earth's umbra, time during which they are powered by batteries. While the batteries are recharged by solar energy, the depth of discharge they reach during eclipse significantly affects their lifetime - and by extension, the service life of the satellites themselves. For batteries of the type that power Iridium satellites, a 15% increase to the depth of discharge can practically cut their service lives in half. We present two new routing metrics - LASER and SLIM - that try to strike a balance between performance and battery depth of discharge in LEO satellite constellations. Our basic approach is to leverage the deterministic movement of satellites for favoring routing traffic over satellites exposed to the sun as opposed to the eclipsed satellites, thereby decreasing the average battery depth of discharge - all without adversely affecting network performance. Simulations show that LASER and SLIM can reduce the depth of discharge by about 11% and 16%, respectively, which can lead to as much as 100% increase in the satellite batteries lifetime. This is accomplished by trading off very little in terms of end-to-end delay.
