Multi-source Broadcast Scheduling Algorithm of Barrage Relay Network in Tactical MANET

Modern tactical edge communication is turning to mobile ad hoc networks (MANETs) since the self-forming and self-healing nature of MANETs are advantageous in such a military environment. However, MANET faces a myriad of challenges in tactical field compared with traditional scenarios. Barrage Relay Network (BRN) is a special MANET designed from the ground up for the demands of tactical edge communications, which defines a rapid, robust and scalable broadcast mechanism based on an autonomous cooperative communication scheme. While, there is no research concerning about time slot scheduling in a multiple source broadcast scenario yet. Naive approach is not optimal in terms of the strict requirements of latency. In this paper, we put forward a centralized topology dependent scheduling algorithm designed for multi-source transmission scenarios in BRNs. Extensive evaluations demonstrate that the performance is not sensitive to the size of network and the throughput of network has improved nearly 23% compared with the naive approach.
