IoT Event Signaling via Cloud Mediator for Community Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems lack effective mechanisms for community-wide responses to events detected by IoT devices, such as tampering or security breaches, without requiring direct ownership or control among devices.
Innovation Solution
A smart device communication system where IoT devices send event signals to community-capable IoT devices, which respond with actions via actuators, and optionally notify the device owner, utilizing cloud services for communication and machine learning to enhance response accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT devices are deployed to monitor and detect events, then event detection capability is improved, but the ability to coordinate community-wide responses is worsened due to lack of ownership and control mechanisms
Solution Approach 1:
The patent introduces cloud-based servers as intermediaries that receive event signals from IoT devices, process the events, and coordinate responses through a centralized system. This mediator enables coordination between devices without requiring direct ownership or control links between them, resolving the contradiction by providing a shared control mechanism.
Solution Approach 2:
The system allows any IoT device to trigger community-wide responses regardless of ownership through universal event signaling. The cloud platform provides universal response coordination capabilities that work across different device owners and device types, enabling versatile community response without requiring specific ownership relationships.
2Productivity
If multiple community-capable IoT devices are deployed to respond to events, then response effectiveness is improved, but system complexity is worsened due to coordination requirements
Solution Approach 1:
The cloud server acts as an intermediary that handles all coordination logic between multiple IoT devices. This centralizes the complexity in a dedicated system rather than distributing it across device-to-device communications, simplifying the overall system architecture while maintaining effective multi-device response coordination.
Solution Approach 2:
The system segments the response coordination function from the event detection function. IoT devices only handle local event detection and signaling, while the cloud platform handles all coordination logic. This segmentation reduces the complexity burden on individual devices while maintaining effective community response.
3Speed
If real-time event responses are implemented, then response speed is improved, but energy consumption is worsened due to continuous monitoring and communication
Solution Approach 1:
The system uses event-triggered periodic action rather than continuous monitoring. IoT devices continuously monitor their local environment but only communicate with the cloud and activate responses when events occur. This periodic communication approach maintains fast response capability while significantly reducing overall energy consumption compared to continuous data transmission.
Solution Approach 2:
The patent extracts heavy computational and coordination tasks from the IoT devices themselves and places them in the cloud platform. This allows devices to use minimal processing power and communication bandwidth for local event detection and signaling, while the cloud handles complex coordination logic, thereby reducing device energy consumption while maintaining response speed.
Data Source
AI summary
A smart device communication system and method are disclosed. The smart device communication system is based on an Internet of Things (IoT) device attached to or in vicinity to an object. In response to an occurrence related to the object, the IoT device sends an event signal that is received by one or more community-capable IoT devices that are geographically co-located with the object. The community-capable IoT device(s) respond by taking one or more actions in response to receiving the event signal. The IoT device and the community-capable IoT device(s) are not co-owned.
