MIL-STD-188-220A parameter optimization for tactical internet

The tactical internet (TI) architecture has evolved into the tactical internet division and below (TIDB) network. One of the major architectural changes is the addition of multicast routing in the internet controller (INC) (with the MIL-STD-188-220A protocol) to support both SINCGARS nets and EPLRS C2 CSMA channels. The TIDB design also employs a disciplined queue structure which will support the addition/extraction of queue entries based upon message precedence, type and age. The MIL-STD-188-220A protocol specifies a number of link layer and radio parameters which are interrelated and have significant cross-correlations which make linear optimization techniques difficult. We used the robust design method, with dynamic signal-to-noise ratio (SNR) and L₁₈ orthogonal array, to perform optimization. The application of Taguchi´s (1987) experiment method further reduced the necessary simulation time. The minute analysis method was applied to select the optimum parameter set
