Abstract:This research investigates Smart Connected Bikes (SCBs) for intelligent urban transportation by combining Blue- tooth Low Energy (BLE) broadcasting with Variable Outer Loop Link Adaptation (VarOLLA) to enable adaptive bike-to-bike communication. Unlike static communication schemes, VarOLLA dynamically adjusts the Modulation and Coding Scheme based on real-time throughput feedback to optimize performance under varying channel conditions. MATLAB simulations evaluated system performance across 1, 2, and 4 nodes within a 140×140 meter urban grid, with nodes moving at bicycle speeds of 18- 28.8 km/h. Statistical analysis using the Mann-Whitney U test revealed that VarOLLA outperforms static MCS configurations in 62-72% of cases, providing a higher throughput.The results demonstrate that VarOLLA-enhanced BLE broadcasting offers reliable and energy-efficient bike-to-bike connectivity in dynamic urban environments, which is a foundational requirement for applications such as collision avoidance and traffic coordination.
