Resource Allocation for Networked Telemetry System of Mega LEO Satellite Constellations

An energy consumption minimization resource allocation strategy in satellite‐terrestrial communication networks

“…Let $$R_{t}^{\rm d}$$ denote the transmission rate of $${\rm S} \text{-} {\rm GS}$$ link in the t th time slot, and $$R_{t}^{\rm d}={B{\log _2}({1 + \frac{p^{\rm } G_{\rm rg} G_{\rm t} L_{t}^{\rm d} L_{t}^{\rm p}}{\sigma ^2} } )}$$ [5], where $$L_{t}^{\rm d}=(\frac{c}{4 \pi d_{t}^{\rm d} f} )^2$$. Let $$R_{j,t}^{\rm d}$$ denote the transmission rate of $${\rm R}_{j}\text{-} {\rm GS}$$ link in the t th time slot.…”

“…In the context of satellite-terrestrial communication networks, a holistic approach is adopted to enhance the overall system performance, focusing on aspects such as power distribution, cache sharing, access scheduling, and user clustering, with the primary goals of maximizing both the cumulative data rate and energy efficiency of the network [4,5]. The existing research clearly underscores the pivotal role played by joint resource allocation in elevating system performance.…”
