Redesigning Cross-Layer Architectures for Performance Optimization in Ad Hoc Networks

Abstract

The traditional OSI model is being replaced in ad hoc networks by a cross-layer approach due to dynamic topologies and poor radio conditions. This method allows different network layers to interact and optimize performance collaboratively. Existing classifications of cross-layer methods are too complex, so this work proposes a simpler, goal-oriented classification to aid in the development of efficient cross-layer protocols and guide future research. Ad hoc networks are moving away from the traditional OSI model toward a crosslayer approach due to their dynamic and challenging environments. This method allows layers to interact and optimize performance collaboratively. The current classification of cross-layer methods is overly complex, so this work proposes a simpler, more effective classification to support better protocol design and future research. Best solution to Adopting a cross-layer design approach in ad hoc networks allows flexible interaction between network layers, improving performance in dynamic environments. A simplified, goaloriented classification of cross-layer methods is proposed to enhance protocol efficiency and guide future research.
