Widespread availability and affordability of devices and easy accessibility of internet has accelerated the pace of ubiquitous computing. Connectivity to the internet has resulted in an exponential growth in terms of content and traffic available on the internet. When the barriers such as type of devices, location, time, and format have become meaningless in the era of ubiquitous computing; the issue of energy consumption and resultant carbon emission is a matter of concern. Energy consumption is an issue in ubiquitous computing, as the majority of the devices involved will be mobile devices that depend on the limited power offered by the battery inside the device. Carbon emission is a concern due to the combined impact made by the devices hooked over to the internet. This chapter discusses the issues related to energy consumption for various activities when the services offered by the internet are availed. The chapter also discusses the challenges to be overcome to achieve conservation of energy consumed by the internet and devices.
Chapter Preview

Internet Usage

The popularity of smart devices used in the ubiquitous computing continues to grow at an exponential rate. This is due to the affordability of devices and availability of 3G, 4G and 5G networks. Currently there are as many mobile devices all over the world, as there are computers. The availability of smart phones is also increasing to the extent that global smart phone activations outnumber global child births by three to one (Tom, 2014). Trends reveal that smart phone customers are expected to reach 2.08 billion by 2016 (Statistia, 2016).
