Connectionless Ad-Hoc Mesh Network for Anonymous Awareness Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ad-hoc mesh networks face challenges in efficiently sharing awareness information due to power consumption, signaling overhead, security, and privacy concerns, limiting their ability to provide continuous and scalable connectivity while maintaining user anonymity.
Innovation Solution
The system implements a connectionless ad-hoc mesh network that uses flooding messages to share awareness information anonymously, optimizing power consumption and reducing signaling overhead by eliminating route maintenance and using short-range radio technologies like WLAN and Bluetooth, with mechanisms for ensuring privacy and anonymity through decoy queries and community-based encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional routing protocols are used in ad-hoc mesh networks, then route establishment is possible, but power consumption increases and signaling overhead increases
Solution Approach 1:
The patent extracts and removes the routing functionality from the ad-hoc mesh network, transitioning from a routed network to a connectionless flooding network. Nodes no longer maintain routing tables or establish routes; instead, messages are flooded throughout the network without predefined paths, eliminating the power consumption and signaling overhead associated with routing protocols while maintaining network connectivity through broadcast mechanisms.
Solution Approach 2:
The patent creates an equipotential communication environment where all nodes have equal capability to send and receive messages without hierarchical routing relationships. Any node can flood messages to any other node through the network without requiring route establishment, making the network topology transparent to the communication process and eliminating power differences between routing and non-routing states.
2Loss of information
If routing tables are maintained for message delivery, then message routing is possible, but signaling overhead increases
Solution Approach 1:
The patent removes routing tables and associated signaling mechanisms from the network. Message delivery is achieved through connectionless flooding where each node forwards received messages to its neighbors without consulting routing tables, eliminating the signaling overhead required for route maintenance, table updates, and route discovery while ensuring message delivery through redundant broadcast paths.
3Reliability
If continuous network operation is maintained, then connectivity is preserved, but battery life is depleted
Solution Approach 1:
The patent implements periodic sleep-wake cycles for wireless nodes, where nodes alternate between active and dormant states. During sleep periods, nodes turn off their radio transceivers to conserve battery power. The connectionless flooding mechanism ensures that messages can still be delivered during sleep periods by being buffered at intermediate nodes and forwarded when the destination node wakes up, maintaining connectivity while dramatically extending battery life through periodic operation.

AI summary
An approach is provided for providing a collaborative reply to a flooding message over an ad-hoc mesh network. A reply message to a flooding message is received by a wireless node within the ad-hoc network. The wireless node monitors for an acknowledgement of receipt of the reply message according to a routing table and initiates a scheduled transmission of the reply message based on the monitoring.
