In this paper, we introduce a new method for cross-layer design in mobile ad hoc networks. We use fuzzy logic system (FLS) to coordinate physical layer, data-link layer and application layer for cross-layer design. Ground speed, average delay and packets successful transmission ratio are selected as antecedents for the FLS. The output of FLS provides adjusting factors for the AMC (Adaptive Modu...

Cross-layer design of routing protocol for mobile ad hoc networks (MANETs) has become a hot research topic in recent years. By integrating physical layer, MAC layer and network layer together for cross-layer design, a cross-layer routing protocol called MIR is proposed in this paper. Via predicting the duration of the interference imposed by the neighbors at every hop along the route, a new rou...

Although cross-layer has been thought as one of the most effective and efficient ways for multimedia communications over wireless networks and a plethora of research has been done in this area, there is still lacking of a rigorous mathematical model to gain in-depth understanding of cross-layer design tradeoffs, spanning from application layer to physical layer. As a result, many existing cross...

Within the HIDENETS project, cross-layer resilience optimisation has been considered in Work Package 3 task 2. This document presents the results of the work in this area, which consists of 2 parts: (1) A general view on cross-layer optimisation is established, which is used to define a general framework. Using this framework, a specific solution for model-based cross-layer optimisation of mess...

The evolution from wired network systems to wireless environments such as Ad-hoc networks enables the emerging of cross–layer systems to improve the wireless network performance. Efficient methods, that may either produce or update cross–layer conceptual models have to be considered. Those models allow an efficient organisation of the wireless systems. In our approach, a cross–layer conceptual ...

This paper deals with the analysis of user perceived visual quality for mobile multimedia services. H.264/AVC is selected for low resolution video encoding, and a mobile UMTS network is considered for the access to services. First, from subjective tests results, the combined impact of different service– and radio network–level parameters is inferred. As a result, different cross–layer adaptatio...
