Dynamic Wireless Ad-Hoc Network Role Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies rely on static infrastructure and require designated roles for devices, limiting the ability to create and maintain dynamic wireless ad-hoc networks without service disruptions or third-party networks.
Innovation Solution
The Dynamic Wireless Ad-Hoc Network (DYNAMET) system allows devices to form networks autonomously, share role functionalities, and update topology asynchronously, using the Redundant Dynamic Protocol (RDP) for data transmission and the Locally Available DYNAMET (LAD) and Globally Available DYNAMET (GAD) architectures to connect multiple networks seamlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static infrastructure and designated roles are used, then network reliability is improved, but adaptability and device versatility deteriorate
Solution Approach 1:
The patent implements dynamic role assignment where devices can switch between different roles (source, destination, relay, gateway) based on real-time network conditions and device capabilities. This dynamic adaptation allows the network to maintain reliability through continuous optimization while improving versatility by allowing any device to perform any function depending on current needs and available resources.
Solution Approach 2:
The system changes operational parameters such as transmission power, routing paths, and role assignments based on detected network conditions, device mobility, and available resources. This parameter adaptation enables the network to maintain reliable communication while accommodating diverse device capabilities and changing environmental conditions.
2Reliability
If scheduled topology updates and control signals are transmitted constantly, then network reliability is improved, but energy consumption and system complexity increase
Solution Approach 1:
Instead of constant updates, the patent employs periodic topology updates triggered by significant network changes such as device entry/exit, link failures, or routing optimizations. This periodic action maintains network reliability by updating only when necessary, significantly reducing energy consumption compared to continuous updates while still ensuring the network remains synchronized and reliable.
Solution Approach 2:
The network performs self-optimization by automatically detecting changes, selecting optimal routes, and assigning roles without external intervention. This self-service mechanism maintains reliability through autonomous adaptation while minimizing energy consumption by avoiding unnecessary control signal transmissions and scheduled updates.
3Adaptability or versatility
If infrastructure-less ad-hoc networks are deployed, then device versatility and network adaptability are improved, but network reliability and service stability deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where devices continuously monitor network conditions, link quality, and available resources. This feedback information is used to dynamically adjust routing decisions, role assignments, and transmission parameters, thereby maintaining service stability and reliability while preserving the infrastructure-less adaptable nature of ad-hoc networks.
Solution Approach 2:
The system performs preliminary actions by pre-establishing multiple alternative routes and backup paths before actual data transmission begins. This preparation ensures that when network conditions change or failures occur, the network can quickly switch to alternative paths without service disruption, thereby maintaining reliability while keeping the network adaptable and infrastructure-less.
Data Source
AI summary
A method for establishing and maintaining a dynamic network designed to allow wireless devices to communicate with one another on an ad-hoc basis. The wireless network is designed specifically to function autonomously, remaining completely independent from relying on any internet service provider or any other subsidiary systems such as any access points or routers. Rather than using central routers, all nodes in the network share the same capabilities as one another, and allow for a dynamic routing protocol to be executed directly by the network nodes.
