abstract = {The fundamental problem of finding transmission schedules for achieving optimal throughput in time division multiple access (TDMA) communication networks is known to be NP-hard. Let        N   be a scheduled    k-time slot TDMA network with    n stations and    m links. We showed that an optimal link schedule for        N   can be computed recursively with a recursion tree of logarithmic depth        O    (  ln  ⁡  m  ) in expectation. Additionally, we showed that optimal link schedules for those TDMA networks, with recursion trees of depth meeting the expectation, can be found in time        O    (      m          2      +      ln      ⁡      k        ). Likewise, we discuss analogous results for computing optimal station schedules of TDMA networks.}
