ABSTRACT
Due to lack of coordination among the layers, the performance of layered architecture posed peculiar challenges in the area of ad hoc wireless networks. To overcome the limitations of layered architecture, cross-layer design was proposed; the idea here is to maintain the functionalities associated with the original layers but to allow coordination, interaction, and joint optimization of protocols crossing different layers. Compared to strict layered architecture, performance of cross-layer architecture is better with reference to protocol design done by dependency between protocol layers. Unlike layering, protocols at the different layers are designed independently because of several analyses of cross-layer design. From a literature survey of many IEEE papers, we came to know that there are many cross-layer design proposals that are weak in performance and implementation.
