Wireless Tag State Transitions for Location Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for localizing wireless tags are inefficient due to the lack of effective control over transitions between unconnected and connected states, leading to suboptimal location tracking and management of wireless gateway associations.
Innovation Solution
A wireless tag system that supports multiple states and uses wireless gateway association information to control transitions between unconnected and connected states, enabling efficient location tracking through the use of whitelists, blacklists, and association rules for managing connections with trusted gateways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless tags continuously transmit beacon signals for location tracking, then location tracking availability is improved, but energy consumption increases
Solution Approach 1:
The wireless tag dynamically transitions between unconnected state (transmitting beacon signals) and connected state (establishing connection with gateway) based on whether a trusted gateway is available. This dynamic state adjustment optimizes energy consumption while maintaining location tracking availability, as the tag only consumes high energy when necessary for connected communication.
Solution Approach 2:
The system changes the communication parameter (connection state) based on gateway trust status. When a trusted gateway is detected, the tag switches from beacon transmission mode to connected communication mode, thereby changing energy consumption parameters while maintaining tracking reliability.
2Measurement precision
If wireless tags establish connections with all detected gateways, then location tracking accuracy is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary authentication and trust establishment between wireless tags and gateways before actual location tracking. Gateways are pre-validated and added to trusted lists, so that when tracking occurs, the tag only connects to pre-approved gateways, simplifying the connection management process while maintaining tracking accuracy.
Solution Approach 2:
The wireless tag autonomously manages its connection state by checking against stored trusted gateway lists and automatically transitioning to connected state when a trusted gateway is detected, without requiring complex external management protocols.
3Use of energy by moving object
If wireless tags use connected state for location tracking, then energy consumption is reduced, but transition control complexity increases
Solution Approach 1:
The system uses feedback from gateway detection and trust list matching to automatically control state transitions. When the tag detects a gateway ID that matches an entry in its trusted gateway list, it receives feedback to transition from unconnected to connected state, and vice versa, simplifying control logic through clear conditional feedback.
4Reliability
If wireless gateway association is manually managed, then security is improved, but ease of operation decreases
Solution Approach 1:
Trusted gateway relationships are established in advance through authentication protocols, and gateway IDs are stored in trusted lists on both tag and gateway sides. This preliminary action ensures security while allowing automatic connection without manual intervention during operation.

AI summary
A capability for localization of a wireless tag based on wireless gateway association information uses a wireless tag supporting multiple states and wireless gateway association information associated with the wireless tag to control localization of the wireless tag. The wireless tag may support an unconnected state in which the wireless tag communicates location tracking information using a wireless beacon signal which may be detected by various wireless gateways and a connected state in which the wireless tag communicates location tracking information via one or more connections with one or more wireless gateways. The wireless gateway association information may include wireless gateway lists (e.g., whitelists, blacklists, or the like), association rules, notification rules, or the like. The wireless gateway association information may be used to control transitions of the wireless tag between the unconnected state and the connected state, to control notifications for the wireless tag, or the like.
