IoT Data Routing for Cellular Network Bandwidth Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face inefficiencies in handling delay-tolerant Internet-of-Things (IoT) data and delay-sensitive data, particularly in cellular networks, where IoT data with longer latency constraints often require centralized processing, leading to bandwidth inefficiencies and potential network saturation due to the need for separate processing nodes.
Innovation Solution
A method and apparatus that differentiate between IoT-type data with longer latency constraints and delay-sensitive data by routing IoT data over a network link to a processing node for baseband processing, while processing delay-sensitive data locally or in a different node, utilizing available bandwidth and buffer management to optimize network resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT data is routed to a centralized processing node for baseband processing, then processing capability is improved, but network bandwidth consumption increases and network saturation occurs
Solution Approach 1:
The patent applies local quality by differentiating processing locations based on data type: delay-tolerant IoT data is processed centrally at the processing node, while delay-sensitive data is processed locally at the network node. This spatial differentiation of processing quality resolves the contradiction by optimizing bandwidth usage without compromising the processing capability needed for IoT data.
2Reliability
If separate processing nodes are used for IoT data, then processing reliability is improved, but device complexity and network resource requirements increase
Solution Approach 1:
The patent implements multi-functionality by enabling a single network node to handle both delay-sensitive data processing and delay-tolerant IoT data routing. The network node performs local processing for time-critical data while simultaneously routing IoT data to appropriate processing nodes, eliminating the need for completely separate processing infrastructure and reducing overall network complexity.
3Loss of energy
If IoT data is buffered and sent when bandwidth is available, then bandwidth efficiency is improved, but processing delay increases
Solution Approach 1:
The patent applies preliminary action by pre-buffering delay-tolerant IoT data at the network node before transmission to the processing node. This allows the system to prepare data for transmission in advance and send it efficiently when bandwidth becomes available, without incurring excessive delays that would affect time-sensitive operations.
4Speed
If network nodes process all data locally, then processing speed is improved, but network resource utilization decreases
Solution Approach 1:
The patent applies segmentation by dividing data processing into two distinct segments: delay-sensitive data is processed locally at the network node for immediate handling, while delay-tolerant IoT data is segmented out and routed to centralized processing nodes. This segmentation allows the network to optimize resource utilization by distributing processing loads appropriately across different nodes based on data requirements.
