Smart Item Transmission Route Selection for Energy Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart item networks face challenges in optimizing energy consumption during data transmission from smart items to a base station, as the energy required for transmission varies significantly based on the transmission path, and existing methods do not efficiently select between multi-hop and single-hop routes to minimize energy expenditure.
Innovation Solution
A method that involves measuring the density of neighboring smart items and parameterizing the energy loss in signal transmission as a function of distance, allowing for the selection between multi-hop and single-hop transmission routes based on energy costs, and adjusting transmission signal energy to reduce energy expenditure, using pre-determined parameters and a monitoring service to ensure efficient connectivity to the base station.

Engineering Contradiction Analysis
1Speed
If single-hop transmission is used, then transmission speed is improved, but energy consumption increases
Solution Approach 1:
The patent implements dynamic transmission route selection that adapts between single-hop and multi-hop modes based on real-time network conditions. The system monitors neighboring smart item density and energy parameters, then dynamically chooses the optimal transmission path - using single-hop when density is low for speed, and multi-hop when density is high to conserve energy
Solution Approach 2:
The system changes transmission parameters including route selection (single-hop vs multi-hop), transmission power levels, and routing decisions based on measured network conditions. By adjusting these parameters dynamically, the system optimizes the trade-off between transmission speed and energy consumption according to the current smart item density and network state
2Use of energy by moving object
If multi-hop transmission is used, then energy consumption is reduced, but transmission time increases
Solution Approach 1:
The system dynamically switches between multi-hop and single-hop transmission modes based on real-time measurements of smart item density and energy parameters. When smart item density is high, multi-hop is selected to conserve energy; when density is low, single-hop is chosen to minimize transmission time
Solution Approach 2:
The patent implements a feedback mechanism where smart items measure the density of neighboring items and monitor energy consumption patterns. This feedback information is used to continuously adjust transmission route selection, creating a closed-loop system that optimizes the balance between energy consumption and transmission time based on actual network conditions
3Reliability
If transmission range is increased, then connectivity is improved, but energy loss increases
Solution Approach 1:
The patent segments the transmission path into multiple hops through intermediate smart items when beneficial. Instead of one long transmission that causes high energy loss, the data is segmented and transmitted through multiple shorter hops, reducing energy loss per transmission while maintaining connectivity through the network
Solution Approach 2:
Intermediate smart items act as mediators or relay nodes in multi-hop transmission. These intermediary items receive and forward data, enabling connectivity over longer distances without requiring single smart items to transmit across the entire range, thus reducing energy loss while maintaining network connectivity

AI summary
A method for selecting between a multi-hop transmission route and a single-hop transmission route for transmitting data from a smart item in a network of smart items to a base station includes receiving signals at the smart item from neighboring smart items in a vicinity of the smart item, measuring a density of neighboring smart items around the smart item based on information in the received signals, and parameterizing a loss of energy in a signal transmitted between a neighboring smart item and the smart item as a function of distance between the neighboring smart item and the smart item. The parameterization is based on information in the received signals. Based on the measured density and on the parameterization of the loss of energy, a multi-hop transmission route or a single-hop transmission route is selected for transmitting data from the smart item to the base station.
