Connectivity, Resource Management and Application-enabling Infrastructure for Networking of Smart Mobile Devices

医疗保健、社交网络、娱乐和高速公路交通管理等领域对电子社会应用的需求不断增长，对智能移动设备（smd）的网络构成了巨大的挑战。这些smd需要高能效、高比特率和异构无线网络支持，以满足新兴应用的需求。特别是，为smd设计的无处不在的个人和社交应用需要更具适应性和节能的网络协议和算法。许多这些社交应用程序倾向于形成参与或协作共同活动的用户集群，在这种情况下，集群之外的应用程序的价值被削弱了。smd通常是电池供电的，需要有效的电力使用来进行通信。无线网络中的干扰以多种方式增加了电力消耗；例如，需要更高的发射功率来维持所需的信号-干扰-噪声预算，并且需要额外的协议处理来在使用中的路径被阻塞时改变路径。拟议的工作将开发技术，以提高smd的功率效率，包括干扰感知协议设计。多样性、合作和异质性的概念将是我们设计的关键组成部分。本研究对该领域做出了重大贡献：(a)减轻了干扰对介质访问控制和路由的影响；(b)以无线通讯的分集技术为基础，将其减低功耗、提高速率和扩展范围的好处转化为改善系统性能；(c)利用局部聚类开发媒介访问控制和路由的干扰和移动性模型；(d)通过干扰感知移动多播路由支持视频流和协作应用；(e)利用当前协作缓存方法的协作决策能力，创建功率感知的协作缓存，以优化其功耗；（六）制定资源综合管理方案。该项目设计的网络和应用程序支持将有助于移动应用程序行业的持续增长。

The growing demand for e-society applications in areas such as health care, social networking, entertainment, and highway traffic management poses enormous challenges to the networking of Smart Mobile Devices (SMDs). These SMDs require power-efficient, high-bit-rate, and heterogeneous wireless networking support to meet the demands of emerging applications. In particular, the ubiquitous personal and social applications designed for SMDs demand more adaptable and power efficient networking protocols and algorithms. Many of these social applications tend to form clusters of users that participate or collaborate on common activities, in which the value of applications outside the cluster is diminished. SMDs are typically battery powered and require efficient power usage for communication. Interference in wireless networks increases power consumption in a number of ways; for example, higher transmit power is needed to maintain the required signal-to-interference-and-noise budget, and additional protocol processing is required to change paths when those in use are blocked. The proposed work will develop techniques to improve the power efficiency of SMDs that includes interference-aware protocol design. The concepts of diversity, cooperation, and heterogeneity will be key components of our design. This research makes significant contributions to the field by: (a) mitigating the impact of interference on medium access control and routing; (b) building on diversity techniques in wireless communication to translate their benefits of power reduction, rate gain, and range extension into improved system performance; (c) exploiting localized clustering to develop interference and mobility models for medium access control and routing; (d) supporting video streaming and collaborative applications through interference-aware mobile multicast routing; (e) creating power-aware cooperative caching by leveraging the collaborative decision-making capacity of current cooperative caching methods in order to optimize its power usage; and (f) developing integrated resource management scheme. The network and application support designed in this project will contribute to the ongoing growth of the mobile application industry.
