Isolated Wireless Nodes Using Mobile Data Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stationary nodes in a network are often isolated from each other, preventing direct communication, especially in situations like emergencies or when traditional communication infrastructure is unavailable, and existing solutions are costly or complex to implement.
Innovation Solution
A stationary short-range wireless communication device and a mobile wireless device collaborate to enable communication between isolated nodes by detecting each other's presence, transferring node data, and using mobile devices as data carriers, with features like access limitation and encryption to ensure secure data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stationary nodes use traditional communication infrastructure, then communication connectivity is achieved, but implementation cost and complexity increase significantly
Solution Approach 1:
The patent introduces mobile wireless devices as intermediary carriers to transfer node data between isolated stationary nodes. Instead of directly connecting nodes through complex infrastructure, mobile devices act as mediators that pick up data from one node and deliver it to another, simplifying the overall system architecture while maintaining communication connectivity.
Solution Approach 2:
The patent implements data copying by creating replicas of node data on mobile wireless devices. The node data is copied from the source node's memory to the mobile device's memory, then transported and copied again to the destination node. This copying mechanism enables data transfer without requiring direct physical connections between nodes.
2Ease of manufacture
If stationary nodes are isolated from each other, then infrastructure cost is reduced, but communication capability between nodes is lost
Solution Approach 1:
Mobile wireless devices serve as intermediary carriers that enable communication between isolated stationary nodes without requiring the nodes to be physically connected or share a common infrastructure. Each node remains independent and isolated, yet communication is achieved through the mobile intermediary that traverses between them.
Solution Approach 2:
The patent transitions from a two-dimensional direct node-to-node connection model to a three-dimensional model where mobile devices move through space to connect nodes. This adds the temporal and spatial dimension of mobile movement, allowing nodes to communicate without direct physical links by utilizing the mobile carrier's movement through the environment.
3Reliability
If mobile devices are used as data carriers, then connectivity between isolated nodes is achieved, but data security risks increase
Solution Approach 1:
The patent applies preliminary anti-action by implementing access limitation mechanisms before data transfer occurs. The node control unit limits access to node data based on predefined criteria, and only authorized mobile devices can retrieve and transport data. This preventive measure counteracts potential security risks before they can manifest.
Solution Approach 2:
The system implements feedback mechanisms where the node control unit monitors and controls data transfer based on access limitation criteria. The system continuously evaluates whether a mobile device meets the requirements for data access and adjusts permissions accordingly, providing ongoing security verification throughout the data transfer process.

AI summary
A stationary short-range wireless communication device acts as a node of a network where nodes are isolated from each other and comprises a communication unit detecting at least one mobile wireless device in the vicinity of the node, a data memory provided for node data (ND) and a control unit controlling the transfer of data between the stationary short-range wireless communication device and the mobile wireless device, which transfer comprises the transfer of node data (ND). The mobile wireless device comprises a data memory for node data (ND) and a control unit (60) that receives the data from the node comprising node data (ND), stores the node data (ND) in the data memory, determines if the mobile wireless device is in the vicinity of another network node and if so transfers the node data to the other network node.
