Cross Layer Analysis and Design with Prescribed Qos using Adaptive Modulation and Coding

In this frame work, a cross layer model which combines Adaptive Modulation and Coding (AMC) at the Physical Layer with admission policy in the Data Link Layer over adaptive wireless links is proposed to maximize the throughput. The proposed cross layer model analysis performance is done by taking into account the QoS parameters such as packet error rate (PER), delay and throughput. The control policy and AMC employed in this analysis possess reduced complexity. By applying admission policy at the Data Link Layer and AMC at the Physical Layer, the throughput is maximized thereby reduce the Packet Error Rate (PER) and delay.
