The importance of optimizing data transfers between mobile computing devices and the cloud is increasing with an exponential growth of mobile data traffic. Lossless data compression can be essential in increasing communication throughput, reducing communication latency, achieving energy-efficient communication, and making effective use of available storage. In this paper we introduce analytical models for estimating effective throughput and energy efficiency of uncompressed data transfers and compressed data transfers that utilize common compression utilities. The proposed analytical models are experimentally verified using state-of-the-art mobile devices. These models are instrumental in developing a framework for seamless optimization of data file transfers.
