EAGER: Collaborative Research: Time Critical Localization in Mobile Networks

基于位置的服务（LBS）是移动网络中最流行的应用类型之一。顾名思义，LBS应用程序的成功取决于两个流水线过程：定位和信息传输。换句话说，直到所有的移动用户都获得了他们的位置，LBS应用程序才能启动。当前方法的定位时间太长，无法支持基于移动网络的时间要求苛刻的应用，因为移动网络中用户的位置会不断变化。该项目设想了一种全新的替代直观的流水线过程方法，其中LBS应用程序可以在所有用户之前启动。职位空缺。智能的优点在于移动本质定位的概念，它有望显著减少(1)定位时间和(2)能量消耗，同时增强位置隐私，保证LBS应用的成功。由于该提议适用于高度不可预测和动态的实时环境，因此存在高风险。如果成功，这种新模式可以激发针对大量时间关键型移动网络应用的科学研究。人们可以期待在包括社交和车辆网络在内的战略利益领域的适用性以及这些应用程序的性能增强方面获得高回报。该项目的广泛影响体现在以下几个方面：(i)这项NSF项目的成果将对促进移动网络使用的普及产生社会影响；美国工业界在其未来的设计和协议中可采用这些新办法，以提高基于地点的服务的可用性及其完整性；（iii）这个EAGER项目从跨学科的角度结合计算机科学、理论计算、电子工程和通信来研究时间紧迫的本地化挑战；产生的软件代码将在开放源码许可下向公众传播；(v)新的跨学科研究生课程将提供给MA/OH的学生，包括少数民族和代表性不足的群体。演示将提供给托莱多公立学校的学生。

Location Based Service (LBS) is one of the most popular types of applications in mobile networks. As the name suggests, the success of an LBS application depends on two pipelined procedures: localization and information transmission. In other words, an LBS application cannot start until all the mobile users have obtained their positions. The localization time of current methods is too long to support time-critical applications based on mobile networks, where users continually change their positions. This project envisions a radically new alternative to the intuitive pipelined procedures approach, where the LBS application can start before all the users? positions become available.The intellectual merit lies in the concept of mobile essential localization, which is expected to significantly reduce both (i) localization time and (ii) energy consumption, while enhancing the location privacy and guaranteeing the success of LBS applications. The proposal entails high-risk as it is applied to real-time environments, which are highly unpredictable and dynamic. If successful, this novel paradigm could motivate scientific investigations aimed at a plethora of time-critical mobile network applications. One can expect high-reward in terms of applicability to areas of strategic interest including social and vehicular networks, and performance enhancements of such applications.The broader impact of this project is reflected in several aspects: (i) The outcomes of this NSF project will have societal impact on facilitating the spread of mobile network usage; (ii) The new approaches may be adopted by US-based industry in their future designs and protocols for enhancing the location based service availability and its integrity; (iii) This EAGER projects investigates the time critical localization challenge from an interdisciplinary perspective combining Computer Science, Theoretical Computing, Electronic Engineering, and Communications; (iv) The resulting software codes will be disseminated to the public under open source license; and (v) New interdisciplinary graduate curriculum will be offered to students in MA/OH including minorities and underrepresented groups. Demos will be offered to Toledo Public School students.
