摘要

Cross-layer design with respect to reference layered architecture is the design of algorithms, protocols and architectures that utilize an available set of interlayer exchanges a superset of the standard interfaces provided by the reference layered architecture. The cross layer approach transports feedback, dynamically via the layer margins to enable the remuneration for e.g. load, latency or other mismatch of requirements and resources by any deal with input to an additional layer. In the original OSI networking model, Layered communication approaches typically separate communication responsibilities into several layers, with a patent definition of the functionality of each layer. Cross layer optimization removes such strict restrictions to permit communication between layers to restore information and enable interfaces. For example, having knowledge of the existing physical condition will help a channel distribution offer at the MAC level in optimizing tradeoffs and achieve throughput maximization. The paper “A Cross Layer Design for Performance Enhancement in LTE-A Systems” consists of four steps: i) Analyze the Various Optimization Techniques ii) Parameters Abstraction iii) Cross Layer Optimization iv) Performance Evaluation.
