ACLI-ware: Dynamic Data Driven Control for Wirelessly Implemented Application SystemsThis project creates an end-to-end management solution for mobile computing that incorporates aspects from the physical wireless communication medium through application requirements. Our middleware(ACLI-ware) moves abstracted information towards higher layers, making them channel aware, and conveys constraints and requirements towards lower layers, making them application aware. In providing applications channel awareness, information about the wireless channel, battery power, neighbors and their distances, lengths of routes, etc. are abstracted from the lower layers towards higher layers. For example, the appearance of a metallic wall may require selecting alternate routes and defining new communication clusters. On the other hand, a dense network requires clever interference-mitigation algorithms and fair-scheduling and routing algorithms. This information is also used by the application to throttle sending rates or adapt data fidelity. To achieve application awareness, applications' constraints such as latency, fairness, quality of service, etc. influence the algorithms used at lower layers. For example, tight latency constraints can lead to smaller communication clusters, shorter allowable routes and quick feedback algorithms from the physical medium. On the flip side, a high bandwidth/throughput requirement entails optimal clustering and high fidelity channel-feedback.This project couples two components seldom brought together: and use of physical channel information for adaptation and the elicitation of application constraints to impact communication characteristics. Thus, there are two key innovations in ACLI-ware: (a) interaction amongst layers, with each layer depending on the other layers' inputs and (b) dynamic solutions, with algorithms that adapt in real-time to varying channel conditions and system requirements.

ACLI-WARE：无线实现的应用程序系统的动态数据驱动控制该项目为移动计算创建了一个端到端管理解决方案，该解决方案通过应用程序要求从物理无线通信介质中结合了各个方面。我们的中间软件（ACLI-Ware）将抽象的信息移动到更高的层，使它们通知频道，并传达对较低层的约束和要求，从而使它们意识到。 在提供应用程序通道意识时，有关无线通道，电池电源，邻居及其距离，路线的长度等的信息被从下层到较高的层中抽象。例如，金属墙的外观可能需要选择替代路线并定义新的通信簇。 另一方面，密集的网络需要巧妙的干扰算法以及公平的安排和路由算法。 应用程序还使用了此信息来节气门发送费率或调整数据保真度。 为了达到应用程序意识，应用程序的约束（例如延迟，公平，服务质量等）都会影响下层使用的算法。例如，紧密的延迟约束可以导致较小的通信簇，较短的允许路线和物理介质的快速反馈算法。另一方面，高带宽/吞吐量需求需要最佳聚类和高保真频道反馈。这对夫妻很少聚集在一起：并使用物理通道信息来进行诱惑和启发应用程序约束以影响通信特征。因此，ACLI-WARE中有两个关键的创新：（a）层之间的相互作用，每个层都取决于其他层的输入和（b）动态解决方案，并采用实时适应不同的频道条件和系统需求的算法。
