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. ********
