2005 IEEE International Symposium on Circuits and Systems, 2005
Many cross-layer design approaches for wireless multimedia transmission over various networks have been proposed. Truly cross-layer design solutions require joint optimization of multimedia coding, transport/network layer, medium access layer, and physical layer transmission strategies and protocols. The solution often becomes impractical because: (i) its computational complexity is high; and (ii) it needs to be recomputed as some inputs, such as ...

Many cross-layer design approaches for wireless multimedia transmission over various networks have been proposed. Truly cross-layer design solutions require joint optimization of multimedia coding, transport/network layer, medium access layer, and physical layer transmission strategies and protocols. The solution often becomes impractical because: (i) its computational complexity is high; and (ii) it needs to be recomputed as some inputs, such as the content characteristics or network conditions change. To this effect, we propose a novel framework for cross-layer design, which features: (i) the joint design strategy selection being adaptive not only to network conditions but also to multimedia content characteristics; (ii) the joint design strategy selection being based on off-line learning to address the computational complexity issue; and (iii) the off-line learning stage employing a new multiple objective optimization solution.
Cross-layer design, by way of joint optimizing the overall network layers in wireless sensor networks, provides an efficient alternative to traditional layered protocol architectures. This paper provides an introduction and comparison of three typical cross-layer frameworks from several aspects such as the targeted problems, major features and advantages, special functionalities, as well as possible drawbacks and shortcomings. Based on the analysis, special design considerations are classified and possible research directions are discussed.
The traditional layered-protocol architecture seems to be inefficient in wireless network environment as the wireless channel is time-varying in nature. The IEEE 802.16 standard which the WiMAX system is based upon is also designed according to such layered-protocol stacks. To obtain overall performance gain however, cross-layer optimization is essential. In this paper, we propose a cross-layer optimization architecture for WiMAX system. It consists of a cross-layer optimizer which acts as an interface between MAC and PHY layers. It gathers and optimized the parameters from both layers to achieve optimum performance gain. Preliminary simulations were conducted to justify the need for cross-layer optimization.
This letter studies the performance of uplink cross layer design for multi- antenna systems with outdated channel state information (CSI). We consider a multi-user system with one base station (with n<sub>R</sub> receive antennas) and K mobile users (each with single transmit antenna). The multi-user physical layer is modeled based on information theoretical framework and the cross layer design can be cast as an optimization problem. In view of the high computation complexity in the optimal solution, we propose a low complexity genetic algorithm as suboptimal solution. We found that with outdated CSI, there is significant degradation in the spatial multiplexing and multi-user diversity gain due to potential packet transmission outage as well as misscheduling. To address the poor performance in the presence of outdated CSI, we propose two simple but effective empirical solutions, namely the rate quantization and rate discounting, to tackle the packet outage problem. For instance, it is well-known that rate quantization imposes system capacity loss in systems with perfect CSI. However, we found that rate quantization can enhance the robustness of system capacity with respect to outdated CSI
In this paper, we propose a novel distributed virtual MIMO scheme for wireless sensor networks. Using the cross layer design, which involves the MIMO techniques on the physical layer and directed diffusion protocol on the network layer, the scheme can optimize the network's energy performance. Comparing with the exiting cluster-based virtual MIMO scheme, the proposed distributed scheme has better stability and scalability.
Mitigating the impact of errors on video quality over wireless network has been a major issue of concern which requires highly efficient and effective scheme. The dynamic and heterogeneous nature of the wireless network requires highly sophisticated approach to mitigate the impact of transmission error on video quality. The trade-off between delay and video quality should be considered while designing such applications to reasonably maintain video quality in wireless channel. In order to significantly reduce the impact of high error bit and error burst on transmitted video, more efficient error correction scheme are needed. In this paper, we paper presents an approach using forward error correction and cross layer mechanism which dynamically adapts with the channel condition to recover the loss packets in order to enhance the perceived video quality. The scenario has been simulated using NS-2 and it shows more dramatic improvement in video quality.
In this paper the edge histogram descriptor, the scalable colour descriptor and the colour layout descriptor defined in the MPEG-7 standard are used for image semantic characterization. A comparative study of the performance and reliability of the image classification based in these descriptors is made. For that, classification methods like neural networks and k-nearest neighbors were used to detect relevant semantic features in images. The descriptors are individually used and combined with different multimodal techniques. A set with 460 images will be used for testing together with a set of 320 training images selected from the TRECVID 2008 development sound and vision database was used.
Recently demand of mu Itimedia application is growing rapidly in real time application such as video streaming. Multimedia applications demand for high quality of service for end user experience. In this field of multimedia communication Mobile-Ad-Hoc network has proven its significance to provide better Quality Of Service (QoS). MANETs consist of mobile nodes which are self-configurable and self-organizing without using any predefined network topology and infrastructure. MANETs suffer from the issue of QoS due to its mobile nature of mobile nodes which causes rapid link failure, channel contention, route maintenance etc. which causes performance degradation of network in terms of throughput, PSNR, delay etc. To address this issue, various researches have been proposed but still Quality of service for more number of users remains a challenging task for researchers, in this work, we propose a novel approach for QoS provision in mobile ad-hoc networks and improving the performance of network. Propose approach utilizes channel modeling, buffer modeling and video distortion & reconstruction modeling. Channel modeling helps to achieve path loss and path gain during video data transmission, buffer modeling utilizes threshold for packet transmission probability and video distortion model is used to achieve packet loss and reconstruction of video packet at receiver end. Proposed approach is compared with existing approach; experimental study shows that proposed model outperforms to improve the overall performance of network.
In this paper, the authors consider the network coding in networks with broadcast channels (called hypernetworks) as the first step for applying network coding to wireless networks. The authors first prove a max-flow min- cut theorem for such networks. While the authors propose an algorithm to achieve this bound, the authors introduce new definitions and provide sufficient tools to extend many of the theorems stated for flows in wireline networks to the case of hypernetworks. As an example, the authors extend the max-flow min-cut condition for feasibility of the point-to-point connection in wireline networks to the case of hypernetworks. Then, the authors extend the algebraic approach of Koetter and Medard, 2003 to the hypernetwork setup whereas we show how the results of recent works based on the model of [Koetter and Medard, 2003] (e. g. random linear coding), can be straightforwardly generalized to the case of the networks with broadcast channels.
