摘要：The latest advances in distributed computing have enabled in the past few years the emergence of a variety of wireless sensor network applications comprising building, health, environment, industry, and military domains. Wireless sensor networks are characterized by constrained power, memory, and computational resources and require a novel design approach. The goal of this thesis is to improve energy performance by employing cross layer design. The goal is achieved by protocol architecture which supports cross layer design and routing protocols which use cross layer information. Energy performance can be enhanced by designing energy aware hardware and software. Energy aware software approach includes development of energy efficient communication protocols and getting benefits from cross layer interaction among layers. In this first, we implement the base station & mobile station. Second, we implement the modulation techniques (OFDM, BPSK, QAM, QPSK) with cyclic prefix values. And lastly, implement the cross layer design. Also we are showing the comparisons using cross layer design & without cross layer design. Simulation result shows the throughput and delay using modulation techniques and cross layer design.
