Performance Enhancements in TDMA-based Tactical Wireless Networks

초록

Unlike analogue voice signal-oriented and narrowband-based conventional systems, the tactical wireless networks have been evolved to deal with multimedia traffics over wideband systems in a past decade. While new waveforms like Wideband Networking Waveform (WNW) have been developed for the physical layer of the future tactical networks, the enhancement in a network layer protocol is not well-reported. In this paper, an enhancement is proposed to improve the performances of the voice packet transmissions using the conventional TDMA-based protocol specified in MIL-STD-188-220 military standard over the wideband environments. By allowing stations to transmit voice packets in Bump-Slot, significant improvements are achieved. It is proved by the extensive simulations.
