Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-hop communication systems, existing technologies face challenges in optimizing the selection of relay nodes to minimize communication costs and reduce the number of nodes involved in relaying information, leading to suboptimal communication efficiency.
Innovation Solution
A node with a relay node determiner that prioritizes relay node candidates with higher communication frequencies and more lower nodes, adjusting communication costs using a weighting factor to determine the most efficient relay path, thereby reducing the number of nodes involved in relaying and minimizing communication costs.

Engineering Contradiction Analysis
1Loss of energy
If relay node selection is based solely on smallest communication cost, then communication cost is minimized, but the number of relay nodes involved increases leading to reduced communication efficiency
Solution Approach 1:
The patent introduces communication frequency as a new parameter to complement the traditional communication cost parameter. By considering both communication cost and communication frequency (how often a node acts as relay), the system changes the selection criteria from a single parameter to multiple parameters, enabling optimization of both communication cost and communication efficiency simultaneously.
Solution Approach 2:
The patent implements a feedback mechanism where the communication frequency of relay nodes is monitored and fed back into the relay node selection process. Nodes that frequently serve as relays are identified and prioritized for selection, creating a feedback loop that improves communication efficiency while maintaining cost-effectiveness.
2Loss of energy
If relay node candidates with lower communication cost are selected, then communication cost decreases, but communication frequency and overall system performance are not optimized
Solution Approach 1:
The patent adds communication frequency as an additional selection parameter alongside communication cost. This multi-parameter approach allows the system to evaluate relay node candidates comprehensively, selecting nodes that offer both cost-effectiveness and proven reliability through their communication frequency performance.
3Ease of operation
If any relay node candidate is selected without prioritization, then selection simplicity is maintained, but communication efficiency and cost optimization are lost
Solution Approach 1:
The patent introduces communication frequency as an automatic selection criterion that works alongside communication cost. This parameter-based prioritization system maintains operational simplicity by using clear, quantifiable metrics while achieving improved communication efficiency through systematic node selection.

AI summary
A node performs multi-hop communication. The node includes a relay node determiner that determines a relay node from a plurality of relay node candidates having path information of a path to a master node. The relay node performs relaying. At least when communication frequencies of the relay node candidates are within a predetermined range, the relay node determiner determines the relay node so that a relay node candidate with a higher communication frequency is more likely to be determined as the relay node than a relay node candidate with a lower communication frequency.
