Radio Communication Device Identification in Ad-Hoc Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless ad hoc networks, it is challenging to distinguish and separate radio communication devices of the same type that are within the radio range and use the same or compatible protocols, leading to undesired networking and increased network load.
Innovation Solution
A method involving coupling radio communication devices via a physical connecting line, using sensors to detect a signal transmitted over this link, and forwarding it to the network for identification, ensuring only devices within the same group establish wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transponders use the same or compatible protocols and are within radio range, then networking capability is improved, but undesired networking and network load increase
Solution Approach 1:
A physical connecting line acts as an intermediary between transponders to establish group affiliation. The line transmits a detectable signal that serves as proof of belonging to a specific group, allowing transponders to distinguish between desired and undesired networking partners without restricting their general networking capability.
Solution Approach 2:
The physical connection is established before wireless communication begins. This preliminary action ensures that only transponders that are physically connected (and thus part of the same group) can engage in wireless networking, preventing undesired networking before it occurs.
2Reliability
If transponders self-organize in ad hoc networks, then network robustness is improved, but group separation and identification become difficult
Solution Approach 1:
The physical connecting line provides a visible or detectable signal that acts as an identifier for group membership. This signal 'colors' or marks the transponders as belonging to a specific group, making group separation and identification straightforward without compromising the self-organizing nature of the network.
3Area of stationary object
If all transponders within radio range can network, then network coverage is improved, but network load and interference increase
Solution Approach 1:
The network is segmented into multiple groups based on physical connections. Each group operates semi-independently, allowing broader overall coverage while reducing the load and interference within each segment. Transponders only communicate wirelessly with others in their physically-defined group, not with all transponders in range.

AI summary
The method involves coupling movable objects (11-14, 21-24, 31-34) e.g. rail-carrying trains, in which radio communication devices (T11-T14, T21-T24, T31-T34) i.e. transponders, are arranged, by physical connection lines (15, 25, 35) i.e. main lines. A signal i.e. aeration, transmitted over the lines is detected by a sensor that is connected with the lines. The detected signal is transmitted to a wireless Ad-hoc-network over the communication device. The communication device connected with the lines over the sensor is identified as belonging to the group of objects. An independent claim is also included for a system for identifying radio communication devices in a wireless Ad-hoc-network.
