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日益增长的需求对智能移动设备(SMDS)的联网提出了巨大的挑战。这些SMD需要高能效、高比特率和异类无线网络支持，以满足新兴应用的需求。特别是，为SMDS设计的无处不在的个人和社交应用要求更具适应性和能效的网络协议和算法。这些社交应用中的许多都倾向于形成参与或协作共同活动的用户集群，这会降低集群外应用的价值。SMD通常由电池供电，需要高效地使用电源进行通信。无线网络中的干扰以多种方式增加功耗；例如，需要更高的传输功率来维持所需的信干噪比预算，并且需要额外的协议处理来在使用中的路径被阻塞时更改路径。这项拟议的工作将开发提高SMDS功率效率的技术，其中包括干扰感知协议设计。多样性、协作性和异质性的概念将是我们设计的关键组成部分。这项研究在以下方面做出了重大贡献：(A)减轻干扰对媒体访问控制和路由的影响；(B)建立无线通信中的分集技术，将其功率降低、速率增益和范围扩展的好处转化为改进的系统性能；(C)利用局部分簇为媒体访问控制和路由开发干扰和移动性模型；(D)通过干扰感知的移动组播路由支持视频流和协作应用；(E)通过利用当前协作缓存方法的协作决策能力来创建功率感知的协作缓存，以优化其功率使用；以及(F)制定综合资源管理方案。该项目中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.
