Energy conservation has been the prime motivation behind the design of conventional protocols for wireless sensor networks (WSNs). However, recent trends toward high data rate multimedia communication over WSNs demand trafficand deadline-aware content delivery with minimum energy expenditure. The basic quality of service requirement in wireless multimedia sensor networks (WMSNs) is time-bound d...
We consider the problem of collectively delivering some message from a specified source to a designated target location in a graph, using multiple mobile agents. Each agent has a limited energy which constrains the distance it can move. Hence multiple agents need to collaborate to move the message, each agent handing over the message to the next agent to carry it forward. Given the positions of...
We consider the problem of delivering m messages between specified source-target pairs in an undirected graph, by k mobile agents initially located at distinct nodes of the graph. Each edge has a designated length and each agent consumes energy proportional to the distance it travels in the graph. We are interested in optimizing the total energy consumption for the team of agents. Unlike previo...
As a research project supported jointly by the National Institute of Information and Communications Technology (NICT) in Japan and the European Commission under its 7th Framework Program, the GreenICN Project has been in operation from 2013 to 2016. The GreenICN project focused on two typical application scenarios, one a disaster scenario and the other a video delivery scenario. The disaster sc...
Timely and energy efficient data delivery is important in wireless sensor network applications. To reduce the probability of wireless sensor network disconnection from user a lower energy consumption gateway must be used, but data delivery speed should be maintained as high as possible. So our purpose is to compare and analyze common approach of building gateway for wireless sensor network appl...
There is very much interest in balancing remote delivered multimedia quality and energy consumption in a heterogeneous wireless network environment. This paper proposes a solution for Energy-efficient Device-differentiated Cooperative Adaptive Multimedia Delivery over wireless networks (EDCAM), a hybrid innovative approach which combines multimedia quality adaptation and content sharing mechani...
Energy consumption has been a critical factor for video services on mobile devices. Existing energy-aware video delivery solutions focus on reducing the energy consumption at either networks or mobile devices, at the expense of decreasing video quality. This article proposes E-Mesh, an energy-aware wireless routing algorithm which balances the need for energy saving with that of maintaining goo...
BACKGROUND In the critically ill, energy delivery from enteral nutrition (EN) is often less than the estimated energy requirement. Parenteral nutrition (PN) as a supplement to EN may increase energy delivery. We aimed to determine if an individually titrated supplemental PN strategy commenced 48-72 hours following ICU admission and continued for up to 7 days would increase energy delivery to cr...
High delivery ratio with low energy consumption is one of design challenges for wireless sensor network routing protocols. In this paper, we identify the drawbacks of pure single path routing scheme and multi -path routing scheme, in terms of guaranteed delivery with low energy consumption. Accordingly, we describe a scheme, in which data is forwarded along a pre-established single path to save...
