The integrated satellite-terrestrial network has the characteristics of large scale, complex, high dynamic and heterogeneousness. Adopting traditional routing methods in the integrated satellite-terrestrial network will cause problems of poor scalability and large routing overhead. Greedy forwarding strategy based on network mapping with hyperbolic geometry works well in large scale network. However, there is no study on applying the network mapping with hyperbolic geometry to complex networks beyond two dimensions, including the integrated satellite-terrestrial network. Based on the method of spherical polar projection, this paper proposes a hyperbolic coordinates mapping algorithm in three-dimensional geographic space suitable for the integrated satellite-terrestrial network. This algorithm gives nodes of heterogeneous layers in the integrated satellite-terrestrial network a unified expression based on four-dimensional hyperbolic coordinates, which helps to quickly identify and locate nodes without global information distribution and scheduling when routing. The routing strategy using greedy forwarding strategy based on this algorithm only costs low storage overhead, as it does not need routing tables. Simulations demonstrate that the performance of the algorithm is hardly affected by the exponential expansion of the network size, which means the property of scalability is excellent. Also, it is stable under heterogeneous network structure, and maintains a stable routing success rate for optimal path selection around 93% with a time complexity of O(n).INDEX TERMS Integrated satellite-terrestrial network, hyperbolic geometry, network mapping, greedy forwarding.

Existing research mainly analyzes the antecedents of successful aging at work from the perspective of the work field, ignoring that in the Chinese context of “familism,” the two fields of family and work permeate each other and may have an impact on successful aging at work. Thus, through a multi-time data collection approach, we obtained a sample of 338 older Chinese employees to examine the impact of work-family enrichment on successful aging at work, the mediating role of occupational future time perspective, and the moderating role of age-inclusive human resource practice. Results indicate that work-to-family enrichment was positively associated with successful aging at work through the mediation of occupational future time perspective. Family-to-work enrichment was positively associated with successful aging at work through the mediation of occupational future time perspective. In addition, age-inclusive human resource practice amplified the positive effects of work-to-family enrichment and family-to-work enrichment on occupational future time perspective. This is an exploration of successful aging at work in the Chinese context, broadening the theoretical research on successful aging at work and providing new ideas for managers on motivating older employees to achieve successful aging at work.
