Multimedia content distribution nowadays becomes the dominating traffic in wireless communication networks. In the meanwhile, battery energy limitation becomes the primary constraint of mobile computing devices. This project explores solutions to bridge the fundamental gap between higher layer traffic-intensive multimedia applications and lower layer energy efficient wireless communication protocols. In particular, this project investigates new cross layer approaches to identify crucial position information from unimportant value information in multimedia and to reduce energy consumption in communication networks with regards to position and value differences. The goal of this project is to establish a new energy-quality optimized framework for wireless multimedia communications that takes advantage of position-value diversity in natural digital images and videos. The research objective is to test the hypothesis that position-based cross-layer resource allocation can improve energy efficiency in wireless multimedia communications. The project consists of three essential components: (1) a unified higher layer position-value separation methodology for various image and video compression formats, (2) energy efficient position-based lower layer resource allocation algorithms to allocate communication resource unequally, and (3) lower layer data-centric wireless relay protocols to transmit multimedia energy efficiently. The algorithms and protocols developed through this project casts new insights on designing energy efficient wireless multimedia communication systems. This project also integrates research findings into related undergraduate and graduate courses and Native American minority student advising.

多媒体内容分发如今成为无线通信网络中的主要业务。同时，电池能量限制成为移动的计算设备的主要约束。这个项目探讨解决方案，以弥合高层流量密集型多媒体应用和低层节能无线通信协议之间的根本差距。特别是，该项目研究了新的跨层方法，以识别关键的位置信息，从不重要的价值信息在多媒体和通信网络中的位置和价值差异方面，以减少能源消耗。 该项目的目标是为无线多媒体通信建立一个新的能量质量优化框架，该框架利用自然数字图像和视频中的位置-值多样性。研究目的是验证基于位置的跨层资源分配可以提高无线多媒体通信中的能量效率的假设。该项目包括三个基本组成部分：（1）一个统一的高层位置-值分离方法，用于各种图像和视频压缩格式，（2）能量高效的基于位置的低层资源分配算法，以分配通信资源不平等，和（3）低层数据为中心的无线中继协议，以传输多媒体能量高效。通过该项目开发的算法和协议为设计节能的无线多媒体通信系统提供了新的见解。该项目还将研究成果整合到相关的本科和研究生课程中，并为美国土著少数民族学生提供咨询。
