When discussing powering wireless sensor network nodes, there are a few major energy consumers: communications, microcontroller and the sensor. We propose a wireless sensor network platform architecture minimizing the energy consumption of sensing. The architecture proposed herein is based on a reactive approach to sensing. A number of possible hardware approaches are evaluated and compared. Th...

The increase in energy demand has raised concerns over adverse impacts on the environment from energy generation. It is important to understand the status of energy consumption for institutions such as Curtin Sarawak to ensure the sustainability of energy usage, and also to reduce its costs. In this study, a preliminary audit framework was developed and was conducted around the Malaysian campus...

The explosion of the Internet traffic volume resulting from both the worldwide broadband subscriber base extension and the increasing number and diversity of available applications and services require a relentless deployment of new technologies and infrastructures to deliver the expected userexperience. At the same time, it also raises the issue of the energy consumption and energy cost of the...

The Sensor Network consists of densely deployed sensor nodes. Energy optimization is one of the most important aspects of sensor application design. Data acquisition and aggregation techniques for processing data in-network should be energy efficient. Due to the cross-layer design, resource-limited and noisy nature of Wireless Sensor Networks(WSNs), it is challenging to study the performance of...

Network lifetime is a critical issue in Wireless Sensor Networks (WSNs). In which, a large number of sensor nodes communicate together to perform a predetermined sensing task. In such networks, the network life time depends mainly on the lifetime of the sensor nodes constituting the network. Therefore, it is essential to balance the energy consumption among all sensor nodes to ensure the networ...

in recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...

Recent advances in wireless networking technologies introduce several energy aware routing protocols in sensor networks. Such protocols aim to extend the lifetime of network by reducing the energy consumption of nodes. Many researchers are looking for certain challenges that are predominant in the grounds of energy consumption. One such protocol that addresses this energy consumption issue is ‘...

Due to the thriving of the mobile devices market, there has been a great momentum in adopting Java technology in embedded mobile devices where optimizing energy consumption is extremely critical. However, since Java Virtual Machines (JVMs) are conventionally used for server side clusters, the energy and memory tradeoff on embedded devices are not well understood. In this work, we attempt to fin...

Power consumption of smartphone applications is one of the major concerns because of the limited battery capacity. An application, although functionally correct, may suffer from unexpected power consumption or energy bugs (ebugs). The existence of such e-bugs is checked for programs with energy profilers although most of them are design bugs. We propose a new model-based power consumption analy...
