Vehicle Security System with Acknowledgment Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle security systems often result in redundant or unnecessary communication between the vehicle security system and the communications network, leading to increased operational costs and user inconvenience.
Innovation Solution
A vehicle security system that includes a wireless transceiver and a security controller, which transmits a message related to vehicle security only if an acknowledgment message is not received from an adjacent communication node, thereby reducing unnecessary communication by avoiding repeated transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security controller continuously transmits vehicle security messages to ensure reliable communication, then the reliability of message delivery is improved, but the quantity of redundant communication increases leading to higher operational costs
Solution Approach 1:
The system implements an acknowledgment feedback mechanism where the monitoring station sends confirmation messages back to the vehicle security system to indicate successful receipt of security messages. The security controller uses this feedback to determine whether retransmission is necessary, thereby ensuring reliable delivery while avoiding redundant communications.
Solution Approach 2:
The system performs preliminary transmission of the security message and waits for acknowledgment before determining whether retransmission is needed. This preliminary action allows the system to avoid unnecessary retransmissions while still ensuring reliable delivery through conditional retransmission based on received acknowledgments.
2Reliability
If the security controller retransmits messages without receiving acknowledgments to ensure delivery, then the reliability of communication is improved, but the operational cost and user inconvenience increase due to redundant network usage
Solution Approach 1:
The acknowledgment message serves as feedback information that enables the security controller to make informed decisions about retransmission. By receiving this feedback, the system avoids unnecessary retransmissions and associated operational costs while maintaining communication reliability through targeted retransmission only when needed.

AI summary
A vehicle security system for cooperating with a communications network includes a plurality of communication nodes in which a given communication node may transmit an acknowledgment message to an adjacent wireless transceiver upon receipt of a message therefrom. The vehicle security system may include a wireless transceiver and a security controller at the vehicle. The security controller may transmit a message related to vehicle security via the wireless transceiver. The security controller may retransmit the message related to vehicle security if the wireless transceiver does not receive an acknowledgment message from an adjacent communication node. The security controller may not retransmit the message related to vehicle security if the wireless transceiver does receive an acknowledgment message from the adjacent communication node.
