In wireless mesh network based on TDMA mode, link scheduling plays an important role in network performance.For fixed-order to-be-scheduled linksets, a heuristic algorithm is proposed to solve the optimal scheduling cycle. Based on the link order, , This paper proposes an optimal link scheduling mechanism based on genetic algorithm, which is based on global optimization.The simulation results show that the algorithm can converge quickly to the minimum scheduling period of the whole network link, The algorithm has higher transmission efficiency and lower implementation complexity.
