Guaranteed Greedy Scheduling algorithm for coal workface PWSN

In view of the proposed model of the PWSN (positioning wireless sensor networks) for coal workface, the uncertainty of the model in the application scenario is analyzed, and the transmission time of the network is too long while the packet loss problem during scheduling is proposed. In order to solve this problem, the process of channel-to-message transmission scheduling is optimized. Combined with PSO (Particle Swarm Optimization) algorithm and multi-level iterative algorithm, a guaranteed greedy transmission scheduling algorithm is proposed. Simulation experiments show that the proposed method effectively reduces the transmission time of packets under the premise of ensuring the packet loss rate.
