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.

基于位置的服务（LBS）是移动的网络中最流行的应用类型之一。顾名思义，LBS应用的成功取决于两个流水线程序：本地化和信息传输。换句话说，在所有移动的用户获得其位置之前，LBS应用不能启动。当前方法的定位时间太长而不能支持基于移动的网络的时间关键应用，其中用户不断地改变他们的位置。这个项目设想了一个全新的替代直观的流水线程序的方法，在LBS应用程序可以开始之前，所有的用户？智力上的优点在于移动的基本定位的概念，其预期显著减少（i）定位时间和（ii）能量消耗，同时增强位置隐私并保证LBS应用的成功。该提案涉及高风险，因为它适用于高度不可预测和动态的实时环境。如果成功的话，这种新的模式可以激发针对大量时间关键型移动的网络应用的科学研究。我们可以期待高回报的战略利益领域，包括社会和车辆网络的适用性，以及这些应用程序的性能增强。该项目的更广泛的影响反映在几个方面：（i）该NSF项目的成果将对促进移动的网络使用的普及产生社会影响;（ii）美国工业界在其未来的设计和协议中可能会采用新的方法，以提高基于位置的服务的可用性及其完整性;（iii）EAGER项目从计算机科学、理论计算、电子工程和通信相结合的跨学科角度研究时间紧迫的本地化挑战;（iv）由此产生的软件代码将在开放源码许可证下向公众传播;（v）将向MA/OH的学生提供新的跨学科研究生课程，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。
