Solution Overview
Problem
Existing wireless mesh networks face inefficiencies in bandwidth allocation, leading to suboptimal performance due to static allocation methods that do not adapt to dynamic data traffic requirements across nodes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static bandwidth allocation is used, then device complexity is reduced, but network performance and adaptability deteriorate
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the bandwidth allocation schedule is continuously adjusted based on real-time data traffic requirements. Each distribution node generates proposed schedules and receives adjusted schedules from neighboring nodes, enabling the system to adapt to changing traffic conditions while maintaining coordinated resource allocation across the mesh network.
2Productivity
If dynamic bandwidth allocation is implemented, then network performance improves, but device complexity increases
Solution Approach 1:
The bandwidth allocation process is segmented into distinct functional components: (1) identifying communication links with neighboring nodes, (2) generating proposed bandwidth allocation schedules based on local traffic requirements, (3) exchanging schedule proposals with neighboring nodes, (4) receiving and applying adjustments to the schedules, and (5) communicating information according to the final adjusted schedule. This segmentation simplifies the overall complexity by breaking down the dynamic allocation process into manageable, modular steps.
3Productivity
If negotiated bandwidth allocation is used between nodes, then bandwidth utilization efficiency improves, but communication overhead increases
Solution Approach 1:
The patent employs preliminary action by having each distribution node pre-generate a proposed bandwidth allocation schedule based on its own data traffic requirements before engaging in negotiation with neighboring nodes. This preliminary preparation reduces the complexity and time required for the actual negotiation process, as nodes arrive at the negotiation already equipped with a reasonable initial schedule that can be quickly adjusted rather than created from scratch through extended negotiation.

AI summary
Apparatuses, methods, and systems for dynamic bandwidth allocation are disclosed. One method includes identifying, by a first distribution node of a wireless mesh network, a communication link with a second distribution node of the wireless mesh network, generating, by the first distribution node, a proposed bandwidth allocation schedule for wireless communication of information between the first distribution node and the second distribution node based on data traffic requirements of the first distribution node, wherein the second distribution node receives the proposed bandwidth allocation schedule, and wherein the second distribution node adjusts the proposed bandwidth allocation schedule based upon data traffic requirements of the second distribution node. The method further includes receiving, by the first distribution node, the adjusted proposed bandwidth allocation schedule from the second distribution node, and communicating, by the first distribution node, information with the second distribution node according to the adjusted proposed bandwidth allocation schedule.
