High-Efficiency Resource Allocation Scheme Introducing the Concept of Resource Sharing Paths in Industrial IoT

Industrial IoT is a key field of the 4th Revolution and wireless network technology essential to support strict industrial requirements. networks have reliable real-time data transmission as main requirement, achieve this, exploits two schemes: routing graph generation which calculates forwarding paths each node, scheduling, allocates communication time frequency resources node. However, since conventional scheduling approaches allocate for all calculated graphs, specific including routes close sink are used more redundantly. This phenomenon leads unnecessary resource wastage poor scalability in environment where number equipment increases. To mitigate these problems, we propose shared path-based scheme efficient management improvement by setting frequently overlapping sections flows resource-sharing paths. The proposed designates sharing path consideration statuses, such congestion reliability. Simulation results show effective terms efficiency compared traditional scheduling.
