Ad Hoc Network Bandwidth Aggregation via Lender Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices often experience fast data transfer rates within local wireless connections but are limited by slow connections to the broader network, necessitating a method to aggregate bandwidth for improved data transfer.
Innovation Solution
The formation and rearrangement of ad hoc networks between borrowers and lenders of bandwidth, utilizing a computer infrastructure to broadcast and select suitable lenders based on criteria such as quality of service and price, creating a virtual fat pipe for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If wireless devices use local wireless connections (e.g., IEEE 802.11a/b/g) for data transfer, then data transfer rate is improved (3-54 Mbps), but transmission range deteriorates (limited to 30-300 ft)
Solution Approach 1:
The patent introduces a relay device as an intermediary between the wireless device and distant network resources. This relay device receives data requests from the wireless device, forwards them to distant resources, and relays responses back, effectively extending the transmission range of high-speed local wireless connections without requiring the wireless device to directly connect to distant nodes
Solution Approach 2:
The patent segments the communication path into multiple hops: wireless device to relay device, and relay device to distant network resources. This segmentation allows the system to combine the high-speed local wireless link with the extended range of other wireless protocols, achieving both fast data transfer and long transmission range
2Length of moving object
If wireless telephony protocols (e.g., EV-DO, CDMA, EDGE) are used for broader network connectivity, then transmission range is improved (miles), but data transfer rate deteriorates (10 kbps to 1 Mbps)
Solution Approach 1:
The patent merges multiple wireless connection types into a unified communication system. The wireless device simultaneously maintains connections using different protocols (e.g., IEEE 802.11 for high-speed local transfer and EV-DO for extended range connectivity), combining their strengths to achieve both fast data transfer rates and long transmission ranges
3Speed
If ad hoc networks are formed to aggregate bandwidth from multiple lenders, then data transfer rate is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where wireless devices automatically discover available bandwidth lenders, negotiate connection terms, and dynamically join or leave ad hoc networks based on their needs. This automation reduces the manual configuration and management complexity that would otherwise be required to form and maintain bandwidth-sharing networks

AI summary
Systems and methods for the formation and rearrangement of ad hoc networks and more particularly to systems and methods for sharing bandwidth in ad hoc networks. The method comprises broadcasting a table to at least one potential lender requesting pertinent lender information and receiving the table from the at least one potential lender with the pertinent lender information. The method further includes selecting one or more lenders of the at least one potential lender which meet preset criteria and establishing an ad hoc network with the one or more lenders based on the selecting.
