MaaS Connectivity Prioritization and Path Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobility-as-a-service (MaaS) systems face challenges in maintaining continuous connectivity for vehicles moving through areas with varying communication infrastructure, particularly due to blockages like tunnels, where traditional discovery methods are inefficient in capturing dynamic contexts and do not prioritize communication traffic effectively.
Innovation Solution
Implementing a system that prioritizes MaaS communication traffic by categorizing packets based on intent and assigning priority levels, using continuous discovery of alternative communication paths, and employing metadata to optimize routing through higher layers of the protocol stack, enabling multi-hop peer-to-peer opportunistic links and redundant path selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional discovery methods are used for MaaS communication, then device complexity is reduced, but reliability of connectivity deteriorates in areas with varying communication infrastructure
Solution Approach 1:
The system performs preliminary actions by continuously discovering and pre-establishing alternative communication paths before connectivity is needed. MaaS nodes proactively map out multiple routing options through the network, storing this topology information for rapid use when primary paths fail or become unavailable, thus ensuring reliable connectivity without adding complex real-time decision-making mechanisms.
2Reliability
If communication traffic is prioritized and multiple paths are discovered, then reliability improves, but device complexity increases
Solution Approach 1:
The patent segments the communication system into distinct functional layers: a discovery layer that continuously maps network topology and identifies alternative paths, a prioritization layer that categorizes traffic by importance, and a routing layer that selects appropriate paths based on traffic priority and available connectivity. This segmentation allows each layer to operate independently with well-defined interfaces, managing complexity while achieving reliable prioritized communication.
3Adaptability or versatility
If continuous discovery of alternative paths is implemented, then adaptability improves, but loss of time increases due to monitoring overhead
Solution Approach 1:
The system implements periodic discovery actions rather than continuous monitoring, where MaaS nodes exchange discovery messages at regular intervals to update their knowledge of alternative communication paths. This periodic approach maintains adaptability by keeping path information current while significantly reducing the time and computational resources required compared to continuous real-time monitoring, thus minimizing loss of time while preserving adaptability.
