IoT Network Packet Header with Node ID Tracking for Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT systems face challenges in efficiently managing and processing messages within networks, particularly in surveillance applications where nodes need to maintain long-term connectivity and perform specific actions based on received signals without repetitive actions and power consumption issues.
Innovation Solution
The proposed solution involves a network packet structure with a header containing a source, destination, node ID, function, counting, and threshold fields, allowing nodes to determine if they should perform actions based on their ID and counting values, thereby preventing repetitive broadcasts and optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nodes continuously broadcast messages to maintain connectivity and perform surveillance functions, then reliability of message delivery is improved, but power consumption increases and redundant actions occur
Solution Approach 1:
The patent applies preliminary action by pre-configuring nodes with unique identifiers and implementing a counting mechanism in advance. When a node receives a broadcast message, it checks whether its identifier is already in the message's identifier list and whether the count has reached the threshold. This pre-established mechanism prevents redundant broadcasts before they occur, ensuring reliable message delivery while avoiding unnecessary power consumption from repetitive transmissions.
2Speed
If nodes perform actions based on received signals without verification, then response speed is improved, but redundant actions occur
Solution Approach 1:
The patent implements feedback by requiring nodes to verify their identifier against the identifier list in received broadcast messages before executing actions. This feedback mechanism ensures that nodes only perform actions when appropriately targeted, preventing redundant operations while maintaining rapid response times. The counting field also provides feedback to terminate broadcasts when thresholds are reached, further improving action efficiency.
Data Source
AI summary
A method and node for processing messages within an Internet of Things (IoT) network and network packet thereof are provided. Multiple fields of a header of a network packet broadcasted over the IoT network are referred to in the method. When a node receives a network packet broadcasted over the IOT network, it checks if the node's ID is recorded in an ID field of the network packet. The node ID is added to the network packet if the network packet does not record the node ID, and the network packet is then broadcasted to the IOT network; otherwise, the network packet is not broadcasted if the node ID has been recorded in the ID field. The node also performs a function indicated in a function field of the network packet when the node ID is not recorded in the network packet.
