Robust Networking for Bandwidth Constrained Mobile Tactical Radios

This work investigates an efficient and robust broadcast / multicast scheme for the bandwidth limited tactical environment. A local neighborhood based broadcast / multicast protocol is enhanced through managing dynamic link conditions to achieve required delivery ratio. Employing a realistic tactical radio model and practical tactical deployment scenarios, the proposed mechanism is evaluated using a network simulator. Compared with one of the most efficient standard protocols, the simplified multicast forwarding, the proposed scheme demonstrates improved efficiency and robustness.
