Mobile Ad-Hoc Network Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks face congestion issues when distributing multimedia content to a large number of mobile entities, such as vehicles, due to limited capacity and increased demand, leading to potential overload situations.
Innovation Solution
Implementing a method that utilizes peer-to-peer (P2P) communication and mobile ad-hoc networks to share content between mobile entities located in close proximity, allowing them to form ad-hoc networks and redistribute content, thereby alleviating the load on the cellular network and enhancing the quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If content is distributed through the mobile communication network to a large number of mobile entities, then content availability is improved, but network overload occurs
Solution Approach 1:
The patent segments the content distribution path into two types: traditional cellular network for general content delivery, and peer-to-peer ad-hoc networks for local content sharing. This segmentation allows the system to handle large numbers of mobile entities by routing some content through local peer networks rather than through the cellular network, thereby avoiding overload while maintaining broad content availability.
Solution Approach 2:
The patent introduces mobile entities themselves as intermediaries in the content distribution process. Instead of all mobile entities directly consuming content from the cellular network, the system enables entities to act as content sources for each other through ad-hoc networks. This intermediary approach distributes the content delivery burden away from the cellular network infrastructure.
2Quantity of substance
If Wi-Fi hotspots are deployed to increase content distribution capacity, then the number of served mobile entities increases, but infrastructure investment increases
Solution Approach 1:
The patent enables mobile entities to serve each other by utilizing their own computational and communication resources. Mobile entities with content can directly share it with nearby entities through ad-hoc networks without requiring external infrastructure like Wi-Fi hotspots. This self-service mechanism eliminates the need for significant infrastructure investment while still enabling high-capacity content distribution.
Solution Approach 2:
The patent makes mobile entities universal content sources by enabling any mobile entity with content to serve as a content distribution node. This multi-functionality allows the system to achieve high distribution capacity without dedicated infrastructure, as ordinary mobile devices perform the function of content servers through the ad-hoc network mechanism.
3Reliability
If peer-to-peer techniques are used for content distribution, then the load on the cellular network is reduced, but the coverage area is limited to one Base Station region
Solution Approach 1:
The patent merges the cellular network and ad-hoc peer-to-peer networks into a hybrid content distribution system. The cellular network provides broad coverage and initial content delivery, while ad-hoc networks provide local content sharing. By combining both approaches, the system achieves both extensive coverage and reduced cellular network load, as content can be distributed through multiple pathways simultaneously.

AI summary
To control content distribution to plural mobile entities, a device for managing the distribution of the content may determine mobile entities which participate in sharing the same content and which are located in the same region. The mobile entities respectively have a first interface for communication with a mobile communication network and a second interface for forming an ad-hoc network with another mobile entity. A message indicating at least one peer address of a peer mobile entity may be selectively transmitted to a mobile entity. The peer address allows the mobile entity to retrieve at least a piece of the content over the second interface from another mobile entity.
