Geographical Routing for Wireless Routers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current routing technologies in wireless telecommunications networks do not efficiently utilize geographical information to route data packets between mobile devices, often resulting in packets being sent through multiple routers across long distances instead of being directed to nearby routers within the same geographical area, which can increase latency and reduce efficiency.
Innovation Solution
Implementing a method where routers analyze the geographical coordinates of destination mobile devices and use a table of established relationships to route data packets directly to nearby routers, employing tunneling protocols to create a logical topology that bypasses the network backbone, allowing packets to be sent based on geographical location rather than traditional network topology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional routing based on network topology is used, then packets can be routed through the network backbone, but the number of hops increases and latency increases
Solution Approach 1:
The patent changes the routing parameter from network topology to geographical location. Routers use geographical coordinates of destination mobile devices to determine the next hop, selecting routers within the same geographical area rather than following traditional network backbone paths. This parameter change directly reduces the number of hops and latency while maintaining manageable routing complexity through geographical-based routing tables.
2Productivity
If packets are routed through multiple routers across long distances, then network coverage is extended, but routing efficiency decreases and latency increases
Solution Approach 1:
The patent applies local quality by routing packets preferentially through routers located in the same geographical area as the destination mobile device. Instead of uniform routing across the entire network, the system creates locally-optimized paths by matching geographical locations, thereby improving routing efficiency and reducing latency for local communications while maintaining network-wide coverage capability.
3Productivity
If geographical information is integrated into routing decisions, then routing efficiency improves and latency reduces, but routing complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-establishing routing tables that contain geographical information about routers and their locations. Routers prepare routing decisions in advance by maintaining ready-to-use routing tables that map destination geographical areas to appropriate next-hop routers. This preliminary preparation reduces real-time routing complexity while maintaining high routing efficiency based on geographical matching.
Data Source
AI summary
Methods are disclosed for routing data, such as a packet, from a source router to a destination router based on geographical information associated with a destination mobile device. A table is accessed to determine whether there is a destination router located in the list of routers that is located within the same geographical area as the destination mobile device. If there is a destination router that meets this criteria, the data is sent to the destination router. But if there is not a destination router that meets this criteria, the data is routed based on network topology.
