Multilevel Network Modeling to Achieve Cross Layer Mechanisms (original) (raw)

Abstract

A new way to improve the performance of ad hoc networks consists in using cross layer mechanisms. Currently, several protocols have demonstrated some reachable performance gain. Global integration on each level of the protocol stack has to be ensured. We present some efficient methods that may either produce or update cross-layer models. Those models, developed on different levels, allow an efficient organisation of the wireless systems and could take several forms. A cross-layer conceptual model is composed of: cross-layer interaction models and interactions description arrays. In this paper, we propose a method which has been applied to a chosen protocol stack.
