Publish Subscribe Broker for Wireless Data Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently processing and transmitting various types of data, such as real-time, fast, and low-priority data, due to latency and bandwidth issues, especially when simulating wireless networks over wired environments, which can lead to excessive traffic and resource wastage.
Innovation Solution
A publish and subscribe communication system is implemented with an external broker that tracks topics, publishers, and subscribers, allowing direct point-to-point data transmission between publishers and subscribers, eliminating intermediate entities and reducing latency, and using topic identifiers to facilitate efficient routing and data prioritization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional broadcast mechanism is used for data exchange in wireless communication systems, then all types of data (real-time, fast, low-priority) can be transmitted, but latency increases and bandwidth is wasted due to excessive traffic
Solution Approach 1:
The patent segments data into different priority levels (real-time, fast, low-priority) and routes them through different paths: high-priority data uses direct point-to-point connections while lower-priority data uses broadcast mechanism, thereby reducing overall latency for critical data
Solution Approach 2:
The patent introduces a broker as an intermediary that manages topic subscriptions and routes data packets efficiently. The broker maintains topic lists and subscriber information, enabling intelligent routing that reduces latency by directing data only to relevant subscribers rather than broadcasting to all nodes
2Adaptability or versatility
If traditional broadcast mechanism is used for data exchange, then data can be transmitted to all nodes, but bandwidth usage increases due to excessive traffic
Solution Approach 1:
The patent applies different transmission qualities to different data types: real-time data receives high-priority direct routing with guaranteed bandwidth, fast data uses medium-priority routing, and low-priority data uses broadcast mechanism, thereby optimizing bandwidth consumption for each data category
Solution Approach 2:
The broker acts as an intermediary that filters and routes data based on topic subscriptions, ensuring that data is transmitted only to nodes that have subscribed to relevant topics. This selective routing significantly reduces unnecessary bandwidth consumption compared to traditional broadcast to all nodes
3Reliability
If manual configuration is used for data routing in simulated wireless networks, then communication paths can be controlled, but system complexity increases and setup time is extended
Solution Approach 1:
The patent implements self-service through automatic topic-based routing: publishers publish data to topics without manual configuration, subscribers automatically receive data by subscribing to relevant topics, and the broker automatically manages routing based on subscription information. This eliminates the need for manual path configuration while maintaining reliable communication
Solution Approach 2:
The broker provides universal functionality by handling multiple tasks: maintaining topic lists, managing subscriber information, routing data packets, and supporting both direct and broadcast transmission modes. This single multi-functional component replaces complex manual configuration systems
Data Source
AI summary
One or more computing devices, systems, and/or methods for implementing a publish and subscribe communication system are provided. A topic identifier comprising publisher and subscriber information and a topic data type of a topic may be generated. The topic identifier and communication address information associated with the topic may be maintained at an external broker. The communication information may be provided from the external broker to a requestor in response to an inquiry regarding the topic identifier. Access to data published to the topic may be provided such that a publisher of the topic directly transfers data of the topic to a subscriber of the topic.
