研究目的
To propose a Smart Sensor Node Group Management Medium Access Control Scheme for efficient data collection and transmission in IoT systems, specifically for logistics and intelligent transportation systems, aiming to reduce energy consumption and enhance system energy efficiency.
研究成果
The proposed MAC scheme effectively groups smart sensor nodes based on distance from the sink node, applies variable buffer thresholds to reduce energy consumption near the sink node, and supports mobility by reallocating group IDs. It enhances the system's general energy efficiency and handles urgent data without transmission delay. Future work includes establishing clearer criteria for travel distance and buffer thresholds, and improving numerical formulas for group ID resetting.
研究不足
The study does not consider the mobility of smart sensor nodes in some simulations, and the criteria for travel distance and buffer thresholds need further establishment. The numerical formulas for group ID resetting require improvement for various system environments.
