A Quality Based Power-Hump Mechanism for High Speed Network Connectivity of Mobile Devices in Digital Living Network Alliance Networks

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, there is need to actively take measures to minimize their power consumption. In this paper, we propose a Power Saving (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–Plug-and-Play (UPP) agents. We define four abstract NC-PS modes and describe their mapping in the case of Bluetooth, a common wireless bearer for mobile devices, now supported in DLNA. Battery power is an important resource in Ad-hoc networks. It has been observed that in Ad-hoc networks, routing control messages and data transmission, these timers are set and refreshed on-demand. Nodes that are not involved in energy consumption do not reflect the communication activities in the network.
