Integrated Gateway Prioritizing Non-IP IoT Device Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT devices with internet protocol (IP) stacks face challenges such as increased costs, size, battery consumption, and processing power, making it difficult to deliver cost-effective and efficient communication solutions for non-network-enabled IoT devices.
Innovation Solution
An integrated gateway (I-GW) supports various protocols, enabling communication for IoT devices without IP addresses, leveraging software-defined networks (SDN) for authentication, prioritization, and data orchestration, and extending battery life by excluding IP stacks, allowing devices to use non-IP addressing schemes like Zigbee, Wi-Fi, or Bluetooth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP stack is included in IoT devices for communication, then communication capability is improved, but device cost and size increase
Solution Approach 1:
The patent extracts the IP stack from the IoT device and relocates it to the gateway. The IoT device only retains the lightweight non-IP protocol stack, while the gateway provides IP addressing and routing functions. This separation reduces device complexity and cost while maintaining communication capability through the gateway's IP-based infrastructure.
Solution Approach 2:
The gateway acts as an intermediary between the non-IP IoT device and the IP-based network. It translates and routes traffic between the device's non-IP protocol and the network's IP protocol, enabling communication without requiring the device to have full IP stack functionality.
2Adaptability or versatility
If IP stack is included in IoT devices for communication, then communication capability is improved, but battery consumption increases
Solution Approach 1:
The patent extracts the power-intensive IP stack from the battery-powered IoT device and relocates it to the gateway. The device only runs the lightweight non-IP protocol stack, significantly reducing its power consumption. The gateway, which is typically powered by the network infrastructure, handles the more demanding IP-based communication tasks.
3Adaptability or versatility
If IP stack is included in IoT devices for communication, then communication capability is improved, but processing power requirements increase
Solution Approach 1:
The patent extracts the computationally intensive IP stack functions from the IoT device and relocates them to the gateway. The device only performs simple non-IP protocol operations, reducing its processing power requirements. The gateway handles IP routing, addressing, and protocol translation, which are more computationally demanding tasks.

AI summary
An integrated GW (I-GW) can be utilized to facilitate communications with Internet of things (IoT) devices that operate without Internet protocol (IP) addresses, based on assigned preferences and/or priority. In one aspect, the I-GW can efficiently deliver existing services for various types of IoT devices (e.g., that support different non-IP protocols) and can create emerging applications across different vertical applications. Further, the I-GW can leverage mobility network elements to authenticate, prioritize connections, and/or enable data orchestration via underlying software defined network (SDN)-enabled capabilities and/or infrastructure services. By utilizing IoT devices that do not have IP stacks, a cost and/or size of the IoT devices can be decreased and battery life can be significantly extended.
