CIF:Small:Collaborative Research: Energy-Aware Location Optimization in Emerging Wireless Networks

近年来，无线网络在生活的不同方面出现了前所未有的新应用。这些新的应用及其相应的机会提高了生活质量，促进了经济增长，并促进了新企业的扩张。展望未来，几个关键的定义方面突出了新兴的无线网络。 这些包括作为实现大规模网络的中心特征的能量效率、延长的网络寿命和“绿色”（即，环境友好）操作。网络在本质上也将是高度异构的，由具有不同功率、通信和计算能力的节点组成。大多数无线节点，为了履行其功能，将被赋予传感能力，连接物理世界和虚拟信息世界。网络将保持高可靠性的连接，以便来自一个节点的信息可以随时随地传送到另一个节点。新兴的无线网络通常被认为是多层的，由节点、它们的接入点和可能更高层的网关组成，并且被赋予移动性。无线网络的宏观行为（在其整体感测能力、能量效率、通信可靠性、连通性和移动性方面）在很大程度上取决于其组成节点的微观布局/位置。本计画探讨在异质、多层、移动的无线网路中，兼顾连结性与自主性的节能节点部署问题。创新的组件利用量化理论，一个看似不太可能的候选人，最初是为信号压缩开发的，作为一个有前途的工具，以解决这些挑战。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

Recent years have witnessed an unprecedented emergence of new applications of wireless networks in different aspects of life. These new applications and their corresponding opportunities have improved the quality of life, provided economic growth, and facilitated the expansion of new businesses. Looking forward, several key defining aspects stand out for emerging wireless networks. These include energy efficiency as a central feature enabling large-scale networks, prolonged network lifetime, and "green" (i.e., environmentally friendly) operation. Networks will also be highly heterogeneous in nature, consisting of nodes with different power, communication, and computational capabilities. Most wireless nodes, in order to fulfill their functions, will be endowed with sensing capabilities, connecting the physical world to the virtual information world. Networks are to remain connected with high reliability so that information from one node may be conveyed to another anywhere, and at any time. The emerging wireless networks are often considered to be multi-tiered, consisting of the nodes, their access points, and possibly higher-tiered gateways, and endowed with mobility.The macro behavior of a wireless network (in terms of its overall sensing capability, energy efficiency, communication reliability, connectivity, and mobility) depends heavily on the micro placement/locations of its constituent nodes. This project explores the problem of energy-efficient node deployment in heterogeneous, multi-tiered, and mobile wireless networks, taking into account connectivity and autonomy. The innovative component exploits quantization theory, a seemingly unlikely candidate that is originally developed for signal compression, as a promising tool to address these challenges.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
