With the increase in smartphone sales and the use of clouds, data synchronization is an essential activity in the mobile applications that aim to keep data up-to-date with information from the application server. This paper proposes an analysis of the main approaches for data synchronization concerning energy, which are the polling and pushing techniques. The results show a substantial gain in terms...
In many application scenarios, such as traffic guidance or ambient living, services need to notify mobile applications about status changes. Such notifications to mobile devices can be realized using two principal approaches, namely push- and pull-based. Apart from functional differences, the two options likely result in different energy consumption, which is an important aspect due to the battery...
Sharing ad hoc resources by offering remote services through an appropriate infrastructure enables new applications for mobile devices. However, the willingness of device owners to contribute resources to such applications remains low as long as they cannot control the amount of energy spent in sharing. In this paper, we explore the potential, limitations, and tradeoffs of ad hoc resource sharing...
This paper presents a distributed proxy solution that enables energy efficient BitTorrent downloads for mobile devices. Instead of using a single proxy, this work focuses on using multiple proxy servers to achieve better bandwidth utilization and thus smaller mobile energy consumption. We present an analytical model that can be used to experiment with different proxy setup and evaluate them from the...
Using proxy servers to cache and shape network traffic can significantly improve the energy efficiency of the participating mobile clients. In this paper, we analyze the implications of hosting a BitTorrent proxy on a broadband router, which pushes the content to a mobile phone over wireless radio (WLAN or 3G). The amount of memory in a router is limited and therefore our interest is on how to use...
