Connection-less Mesh Networking via Periodic BLE Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mesh or peer-to-peer networking protocols, such as Bluetooth Low Energy (BLE), incur high overhead and performance issues due to the need for establishing connections and performing error checking, making them unsuitable for network systems requiring rapid data transmission and node awareness.
Innovation Solution
A connection-less mesh network is formed by nodes that periodically broadcast an identifier and data payload at predetermined frequencies using Bluetooth Low Energy, allowing for rapid many-to-many communication without establishing connections, enabling nodes to dynamically update their information and resolve conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection establishment and error checking are performed in mesh networking protocols, then data transmission reliability is improved, but communication overhead and system complexity increase significantly
Solution Approach 1:
The patent extracts and removes the connection establishment and error checking components from the communication protocol. Nodes broadcast data packets without establishing connections or performing CRC checks, eliminating the complexity associated with these functions while maintaining basic data transmission capability.
Solution Approach 2:
The patent employs disposable, short-lived broadcast packets that do not require acknowledgment or retransmission. Each packet is transmitted once and discarded, avoiding the overhead of connection management and error checking while enabling rapid data propagation through the mesh network.
2Manufacturing precision
If connection management and error checking are implemented, then data transmission accuracy is improved, but communication speed and responsiveness deteriorate
Solution Approach 1:
The patent enables continuous broadcasting by all nodes simultaneously without interruption for connection management or error checking. Each node independently and continuously broadcasts its data packets, maintaining high communication speed and responsiveness while accepting occasional data loss or duplication.
Solution Approach 2:
The patent skips the error checking and retransmission steps entirely. Nodes broadcast data packets and move on to the next transmission without verifying accuracy or requesting retransmissions, prioritizing communication speed over transmission accuracy.
3Reliability
If connection establishment procedures are followed, then secure two-way communication is achieved, but bandwidth efficiency and scalability worsen
Solution Approach 1:
The patent makes each node universally functional as both broadcaster and receiver simultaneously. All nodes broadcast their data packets to the entire network at once, eliminating the need for pairwise connection establishment and enabling efficient use of available bandwidth through parallel transmissions.
Solution Approach 2:
The patent employs periodic broadcasting where nodes transmit data packets at regular intervals. This periodic action allows efficient bandwidth utilization through time-division multiplexing while maintaining scalability, as nodes can broadcast independently without coordinating connections with other nodes.
Data Source
AI summary
A node forms a connection-less mesh network with one or more other nodes. The node controls to generate an identifier that identifies the node; to update the identifier and a data payload; to periodically wirelessly broadcast, at a predetermined frequency, broadcast-information that comprises the generated identifier and the updated data payload; and to periodically receive, at a predetermined frequency, other-broadcast-information which is the broadcast-information respectively broadcast from each of the one or more other nodes. The one or more processors performs the update of the identifier and the data payload in accordance with the other-broadcast-information from the other nodes.
