A Network Connectivity Power-Saving Mechanism for Mobile Devices in DLNA Home Networks
Dimitris N. Kalofonos, Mika Saaranen · 2007
Abstract—Mobile devices are increasingly assuming an important role in “smart home ” network environments. Although their computing, storage and networking capabilities have evolved significantly, these devices remain power-constrained and, therefore, need to actively take measures to minimize their power consumption. In this paper, we propose a Network Connectivity Power Saving (NC-PS) mechanism for mobile devices in Digital Living Network Alliance (DLNA) home networks, which allows them to conserve power without compromising their higher-layer functionality. The proposed mechanism introduces a level of indirection that abstracts the low-level low-power support of different wireless bearers and exposes a uniform interface to higher-layer entities, such as applications and Universal–Plugand-Play (UPnP) agents. We define four abstract NC-PS modes and we describe their mapping in the case of Bluetooth, a common wireless bearer for mobile devices, now supported in DLNA.
