Efficient net access scheduler in MIL-STD-188-220A

The presence of multiple stations on a single net requires a method for controlling the net access opportunities for each station. In order to minimize conflicts, various net access delay (NAD) schemes have been proposed to access CSMA timing slots randomly for channel requests. The current load factor NAD (L-NAD) algorithm used the load factor (F _load) which was computed based on a neighboring station´s precedence level and the number of FMUs required to transmit all of the data at the precedence level. It is desirable to adjust the scheduling interval to give neighboring stations with higher priority or longer queues of equal priority more opportunities to transmit. Since the NAD scheduler algorithm is a most critical control factor for network performance, the current L-NAD is modified to improve further the performance of the tactical Internet division and below (TIDB)
