Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks, especially in 5G systems, face high energy consumption during data packet transmission, which is exacerbated by multi-hop wireless network topologies lacking specific solutions to optimize energy intensity across different transmission paths and configurations.
Innovation Solution
A method that associates energy budget indication information with data packets, allowing network nodes to route and schedule transmissions based on energy intensity, enabling the selection of more energy-efficient paths and configurations, thereby reducing overall energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-hop wireless network topologies are used to enable flexible routing paths, then network versatility and routing options are improved, but energy consumption increases
Solution Approach 1:
The patent applies preliminary action by associating energy budget indication information with data packets before transmission. This allows network nodes to make informed routing decisions about next hops based on pre-calculated energy budgets, preventing energy-intensive routing choices before they are made. The energy budget is determined in advance and attached to the packet, enabling proactive energy management rather than reactive optimization.
Solution Approach 2:
The patent implements parameter changes by introducing energy budget indication information as a new parameter that dynamically influences routing decisions. The energy budget parameter is associated with each data packet and used by network nodes to select next hops, transforming the routing process from static path selection to dynamic parameter-based optimization. This parameter change enables the system to adapt routing paths based on energy constraints.
2Use of energy by moving object
If energy budget indication information is associated with each data packet to optimize routing decisions, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the energy management function into discrete components: energy budget indication information is segmented and associated with individual data packets rather than being managed as a centralized system state. Each network node independently processes the energy budget parameter attached to each packet it receives, eliminating the need for complex centralized energy management while achieving distributed energy optimization.
Solution Approach 2:
The patent implements self-service by enabling data packets to carry their own energy budget information, allowing them to essentially guide their own routing decisions. Network nodes simply read the energy budget parameter from the packet and make routing decisions based on it, without requiring complex external energy management systems. The packet itself serves as the carrier of its own energy management instructions.

AI summary
A method for routing of data packets includes: in a first step, energy budget indication information is associated or applied to at least one specific data packet, wherein energy budget indication information or its information content is related to the energy intensity of the transmission of the at least one specific data packet; and in a second step, subsequent to the first step, a routing and/or scheduling decision regarding a next hop is taken by a specific preceding network node in dependency on the energy budget indication information or its information content, indicating available and/or residual energy budget.
