Integrative, Hybrid and Complex SystemsIan F. AkyildizGeorgia Institute of TechnologyCross-layer Communication Module for Ultra Wide Band Based Wireless Multimedia Sensor NetworksIntellectual Merit: The availability of inexpensive hardware, such as complementary metal oxide semiconductor (CMOS) cameras and microphones that are able to capture multimedia content from the environment, has fostered the development of wireless multimedia sensor networks (WMSNs). WMSNs consist of wirelessly-connected devices that allow retrieving video and audio streams, still images, and scalar sensor data. The realization of WMSNs requires the sensor network paradigm to be rethought in view of the need for mechanisms to deliver multimedia content with a predefined level of quality of service (QoS). In view of these challenges, the objective of this project is to develop a novel cross-layer module for multimedia traffic in WMSNs. Several key elements will be investigated to provide QoS and to exploit the correlation that is present in WMSNs. The architecture of WMSNs will be first developed. Then, a cross-layer controller unit, which enforces network layer QoS support, will be developed. To capture the correlation present in WMSNs, a theoretical framework will be developed. Based on this framework, an application-aware cross-layer module will be developed, with the goal of establishing routes between correlated nodes to enable in-network processing and further improve the energy efficiency of the network. Our communication module will deliver QoS to heterogeneous applications in WMSNs by combining cross-layer interactions among functionalities handled at different layers of an ultra-wideband (UWB) protocol stack with correlation-aware multimedia processing techniques, which will be used to reduce in-network the amount of data to be transmitted according to application requirements.Broader Impact: The research has the potential to impact wireless multimedia sensor network research and technology. Topics on wireless multimedia sensor networks with ample input from the research will be introduced in two classes taught by the principal investigator at Georgia Tech. The project will support two graduate students. The development of a cross-layer protocol suite in the context of a simulator will serve as an evaluation platform for future researchers. The results from the proposed work will be published in conferences and journals.

基于宽带的无线多媒体多媒体传感器网络智能良好的综合，混合和复杂的系统主义Akyildizgeorgia技术杂交式通信模块：廉价硬件的可用性，例如互补金属氧化物半导体（CMOS）cameras and Microphone的互补金属的可用性传感器网络（WMSN）。 WMSN由无线连接的设备组成，允许检索视频和音频流，静止图像和标量传感器数据。 WMSN的实现要求将传感器网络范式重新思考，因为需要机制提供具有预定义水平的服务质量（QOS）的多媒体内容。 鉴于这些挑战，该项目的目的是为WMSN中的多媒体流量开发一个新颖的跨层模块。 将研究几个关键要素以提供QoS并利用WMSN中存在的相关性。 WMSN的架构将首先开发。 然后，将开发一个跨层控制器单元，该单元将开发网络层QoS支持。 为了捕获WMSN中存在的相关性，将开发一个理论框架。 基于此框架，将开发一个应用程序感知的跨层模块，目的是在相关节点之间建立路线以实现网络处理处理并进一步提高网络的能源效率。 我们的沟通模块将通过在超宽带（UWB）协议堆栈的不同层上处理的功能上的跨层相互作用结合使用与相关性的多媒体处理技术的功能上处理的跨层相互作用，从而向WMSN中提供QoS。和技术。 无线多媒体传感器网络的主题将在佐治亚理工学院的首席研究员教授的两个类别中引入研究。 该项目将支持两名研究生。 在模拟器的背景下，开发跨层协议套件将作为未来研究人员的评估平台。 拟议工作的结果将在会议和期刊上发表。
