MIL-STD-188-220 standard specifies protocols for narrowband and voice-based tactical communication devices. However, the future tactical communication devices require broadband services for accurate command and control. In this letter, the enhancement for MIL-STD-188-220-based systems is proposed for use over wideband channels. Unlike the operation defined in the standard, transmissions in Bump-Slots uses P-Persistence method and give the higher p to stations experiencing longer delays. The proposed method is extensively evaluated and the performance enhancements are proved.

Unlike analogue voice signal-oriented and narrowband-based conventional tactical systems, the future tactical networks will deal with packet-based voice traffic over a wide channel bandwidth. In this paper, a method is proposed to improve the performance of voice packet transmission for MIL-STD-188-220 military standard-based wideband communication systems. By utilizing Bump-Slots for voice packet transmissions, significant improvements are achieved. This is confirmed by extensive simulations.
