F ive NAD ( N ewt ork A cce Delay) algorithm are the m ain m ean of tream control in the protoco.l In order to re olve how to choo e appropriate NAD algorithm , the protocol perform ance i analyzed ba ed on network mi u lation under tactical internet background. F inally, different NAD algo- rithm perform ance and characteri tic are com pared on the a pect of network throughput, end to end de- lay, m e age precedence, node equ ity and realization co t. The e conclu ion w illbe valuable in practice. Key w ord s T actical Internet; M ilitary packet radio; M IL- STD - 188- 220C; NAD algorithm; S mi ulation M IL- STD 188- 220C ( 220C
