Link scheduling plays an important role in the performance of time division multiple access(TDMA) based
wireless mesh networks. A heuristic algorithm to solve the near optimal scheduling length is proposed for link list with fixed sequences. As the performance is much more affected by the sequence of the link list, the link scheduling scheme to sort the overall network link list based on genetic algorithm is proposed. Simulation results show that the proposed scheme can converge to the optimal schedule length more rapidly, having a better transfer efficiency and a lower implementation complexity than the existing algorithms.
