Adaptive Multi-Input Medium Access Control (AMI-MAC) Design using Physical Layer Cognition for Tactical SDR Networks

Tactical software defined radio (SDR) networks demand stringent requirements of latency, throughput, and reliability. In the past, significant efforts have been made to achieve maximal efficiency with modifications improvements either in an individual layer or through cross-layer design its working protocol. this paper, we propose a novel consisting adaptive multi-input medium access control (AMI-MAC) along intelligent channel allocation scheme supported by multiband multimode physical layer. A cognitive engine further empowers approach high improved quality service (QoS), range capabilities. The proposed exhibits mixed use narrowband wideband waveforms accommodating different as per demanded QoS. uniqueness enables SDR operate hybrid topology receiving multiple signals bandwidths same configuration RF front end. AMI-MAC ensures reduction both data phase latency. MAC utilization time frequency spectrum. Bandwidth delay optimization is also managed trio layer, MAC, cognition reduce latency desired Simulation results are presented show superiority over conventional tactical MAC.
