Efficient Storage Approach for Big Data Analytics: An Iterative-Probabilistic Method for Dynamic Resource Allocation of Big Satellite Images

Abstract

Satellite images play a crucial role in ecology as they provide rich information about the Earth's surface. The deep analysis of satellite images presents a vast challenge due to the sheer size of the data that needs to be managed. Sophisticated storage solutions are required to handle the ever-increasing velocity of incoming data and to deal with potential latency or data loss. Storage balancing ensures ecient allocation and distribution of storage capacity across a system, which involves monitoring, analyzing, and adjusting how data is stored to optimize performance, minimize downtime, and maximize cost savings. Additionally, storage balancing helps avoid data bottlenecks by automatically redistributing data across multiple resources. While many solutions have been proposed to balance storage, no polynomial solution is available. This paper addresses the issue of transmitting a considerable amount of satellite images across the network to various storage supports. The challenge is to nd an eective way to schedule these satellite images to the storage supports that lead to equitable results in distribution. Many heuristics and enhancement methods are proposed to solve this problem. The eectiveness of the algorithms presented in this paper was tested and analyzed through extensive testing. The experimental study shows that the proposed heuristics outperform those developed in the literature. Indeed, in 73.8% of cases, the best-proposed algorithm, the best iterative-selection satellite images algorithm (BIS), reached the best solution compared to the best algorithm in the literature and the other proposed algorithms. The BIS algorithm obtained an average gap of 0.147 in an average running time of 1.0654 s.

The concept, technical architecture, applications and impacts of satellite internet: A systematic literature review

“…Few studies have explained the fundamental theories and enabling mechanisms of Satellite Internet, and the research theories and perspectives applied are relatively fragmented, which is insufficient to achieve a global consensus on unified standards of Satellite Internet [ [9] , [10] , [11] ]. Furthermore, the continual extension of the Satellite Internet technology ecosystem led by one country can encompass data and information across many fields, such as global aviation, navigation, and finance [ 12 , 13 ]. As orbital and frequency band resources become increasingly scarce, they pose great challenges to the national network sovereignty and security of other countries [ 14 ].…”
