AI Technical Summary
Existing power distribution IoT communication solutions struggle to simultaneously guarantee link reliability, air interface efficiency, load balancing, and service timeliness in mountainous transformer substations. Furthermore, traditional routing methods suffer from high control overhead and slow recovery when links degrade or nodes become congested, making them ill-suited for the rapid recovery requirements of event-driven scenarios.
A multi-gateway long-distance radio dynamic routing optimization method is adopted. By constructing a LoRa multi-hop communication network model, the air interface occupancy time (ToA), the expected number of transmissions per link, and the node load factor are calculated to construct the service-aware composite link cost. Combining the candidate path hop count and the gateway load factor, the total path cost is constructed, and an event-triggered function is set to perform local incremental repair, thereby realizing a dynamic routing closed loop.
It improves the transmission efficiency of LoRa multi-hop links, stabilizes paths and associations in multi-gateway scenarios, reduces rerouting control overhead, enhances network adaptability, improves the reliability and balance of data transmission, and reduces unnecessary global reconfiguration.
