Abstract Space information networks (SINs) are responsible for communications, information
processing, and earth observation. Traditional time-expanded graphs (TEG) cannot …

In this paper, we investigate the maximum flow routing strategy with dynamic link allocation
under a constraint on the number of transceivers for space information networks (SINs) …

The contact window scheduling technology supports various space mission requirements of
the satellite information network. The continuous emergence of new space missions …

Discrete time-variant nonlinear optimization (DTVNO) problems are commonly encountered
in various scientific researches and engineering application fields. Nowadays, many …

The satellite data relay networks (SDRNs) hold great promise in 6G communications for the
timely offloading of the global traffic. Since the delay performance is regarded as one of the …

Software defined network technique is a novel approach introduced to manage low earth
orbit (LEO) small satellite networks. One important challenge is the allocation of the scarce …

We study the collaborative data offloading problem for earth observation satellite networks
(EOSNs) that allows light-loaded satellites to assist heavily-loaded ones to offload earth …

Relay satellite network has become a promising architecture to provide rapid-response data
offloading services for delay-sensitive space data. However, stochastic resources and …
