Wireless Cluster Affiliation for Dynamic Topology Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks for clusters of communicating electronic devices, such as those monitoring containers, face challenges in energy conservation and effective data transmission due to obstacles and dynamic topologies, leading to data loss and inefficient energy use when head nodes are unable to perform their roles effectively.
Innovation Solution
A method allowing nodes to self-designate as heads only if they can perform their roles effectively and enabling loose nodes to request affiliation with a cluster on demand, using verification messages to ensure cluster persistence and adapt to changing network topologies, thereby optimizing energy usage and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If head nodes are designated in wireless communication networks for data aggregation and transmission, then data transmission efficiency is improved, but energy consumption increases and network reliability deteriorates when obstacles block head node communication
Solution Approach 1:
The patent introduces intermediary relay nodes that forward data between member nodes and head nodes when direct communication is blocked by obstacles. This mediator mechanism ensures continuous data transmission and maintains network reliability even when head nodes cannot directly receive data from all members.
Solution Approach 2:
The patent implements dynamic head node selection and relay node appointment based on real-time network conditions, obstacle detection, and communication availability. This dynamic adaptation allows the network to reconfigure itself when obstacles block communication paths, maintaining both efficiency and reliability.
2Adaptability or versatility
If nodes continuously verify cluster affiliation and update routing information, then network adaptability to dynamic topologies is improved, but energy consumption and message overhead increase
Solution Approach 1:
The patent implements periodic affiliation verification messages instead of continuous verification. Nodes send verification messages at scheduled intervals and update routing information periodically, reducing energy consumption while maintaining network adaptability to topology changes.
Solution Approach 2:
The patent enables nodes to autonomously determine their cluster affiliation status and update their routing tables based on received verification messages, without requiring constant centralized control. This self-service approach reduces control overhead and energy consumption while maintaining adaptability.
3Device complexity
If random head node selection is implemented in wireless sensor networks, then device complexity is reduced, but network reliability and energy efficiency worsen due to inability to guarantee effective head performance
Solution Approach 1:
The patent implements feedback mechanisms where nodes evaluate head node performance based on data aggregation efficiency, communication reliability, and energy consumption. This feedback information is used to dynamically select and appoint head nodes, ensuring effective performance while maintaining reasonable system complexity.
Solution Approach 2:
The patent performs preliminary evaluation of potential head nodes based on their capabilities, position, and resource status before designating them as heads. This preliminary assessment ensures that selected head nodes can effectively perform their roles, improving reliability without requiring complex ongoing management.
4Loss of information
If verification messages are sent to confirm cluster affiliation before data transmission, then data loss is reduced, but communication overhead and transmission delay increase
Solution Approach 1:
The patent performs cluster affiliation verification as a preliminary action before data transmission begins. Nodes confirm their cluster membership and establish routing paths in advance, ensuring data integrity while minimizing delay during actual data transmission by having verification results pre-cached.

AI summary
The invention concerns a wireless communication network that is particularly innovative and robust when said the network, comprising a plurality of nodes, has a dynamic topology. A method implemented by a communicating electronic device acting as a free node of said the network can request, on demand, a procedure for affiliation with a second device that is a member of a cluster. Affiliated with the cluster, a device implementing the method can communicate with a third device acting as cluster head in the same way as a member of the cluster. Such an invention makes it possible, in particular, to operate a traceability system for containers cooperating respectively with such devices on a storage area or a transport platform.
