Roaming Distributed Content Aggregation for Satellite Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite data transmission faces challenges with high bandwidth costs and interference from terrestrial weather and electromagnetic emissions, particularly when transmitting data over long distances where line-of-sight transmission is impractical and wireline communication is unavailable.
Innovation Solution
A roaming distributed content aggregation system is implemented, where content requests from mobile communication platforms (MCPs) are cached and fulfilled via high-bandwidth links when within range of a port or another MCP, using a Central Bandwidth Manager (CBM) to optimize bandwidth allocation and provide time delay indications for content availability, allowing users to prioritize requests for faster access.

1Length of moving object
If satellite data transmission is used for long-distance communication, then line-of-sight transmission is achieved, but bandwidth cost increases and interference from terrestrial weather and electromagnetic emissions occurs
Solution Approach 1:
The system pre-loads content to mobile communication platforms (MCPs) while they are within range of high-bandwidth connections (port Wi-Fi or other MCPs), so that content is already cached and available when the MCP is at sea with limited satellite bandwidth. This preliminary action eliminates the need to transmit large amounts of data over expensive satellite links during actual use.
Solution Approach 2:
Other MCPs act as intermediary nodes that cache and share content with MCPs at sea. When an MCP needs content, the system checks if other MCPs have it cached, and if so, transfers it through those intermediaries rather than requiring direct satellite transmission, reducing bandwidth costs.
2Loss of energy
If content is cached on MCPs for later access, then bandwidth cost is reduced, but time delay occurs for accessing content
Solution Approach 1:
The system provides real-time feedback to users about content availability status, time delays, and data plan impacts through data meters and notifications. This feedback mechanism allows users to make informed decisions about whether to wait for cached content or prioritize immediate access by purchasing additional bandwidth.
Solution Approach 2:
The system dynamically adjusts content delivery based on real-time conditions such as MCP location, available bandwidth, cached content status, and user preferences. The content aggregation system can switch between different delivery modes (cached content, priority satellite transmission, or deferred delivery) based on current system state and user needs.
3Productivity
If a centralized bandwidth management system is implemented, then bandwidth allocation is optimized, but system complexity increases
Solution Approach 1:
The bandwidth management system is segmented into distributed components: local content aggregation software on each MCP, central coordination servers at ports, and peer-to-peer communication between MCPs. This segmentation allows intelligent bandwidth management without requiring a single complex centralized controller, distributing the computational burden across multiple simpler nodes.
Data Source
AI summary
A system includes a wireless interface to a central computer system that communicates with multiple mobile communication platforms (MCPs), and logic to receive a request for content from a device aboard a first MCP, the content not stored on the first MCP, the device having an associated data plan. The system includes logic to communicate the request for content to the central computer system, and to receive from the central computer system an indication of a time delay before the content will be available to the device on a non-priority basis, and logic to notify the device of the time delay, and to provide the device with an indication of an impact that receiving the content on a priority basis will have on the data plan.”
