Where is Bluetooth in the Internet of Things? Essays

Amplitude/Loudness, Intensity: There are 3 classes of Bluetooth technology depending on their power consumption and their range and this is shown in table 1. As seen in table 1, Class 1 is around the same level as mobile phones and the other 2 classes are much lower, so therefore Class 2 and 3 are considered less hazardous than mobile phones. (Layton & Franklin, [date unknown])

The technology is being used in many of the devices that are used in business and at home today. While there can be a cost savings in many applications, there are also issues with security and the ability of devices from different manufactures being able to work together. At this time, there have not been any standard protocols developed to allow easy integration of devices from different manufacturers on a network.

A decade ago there weren’t many people who had objects that were able to connect to the internet and if you were an early adopter of smart phone technology you probably had one or maybe two objects that had the ability to connect to the internet. But today almost every person in the world has more than one object that connects to the internet. Anything from smartphones, smart TVs, Cars, Game systems and even refrigerators are now able to connect to the internet. It estimated by 2020 there will be 50 billion objects connected to the internet. This is the Internet of Things. A network of internet connected objects that are able to collect and exchange data using embedded sensors (businessinsider). In this paper I will discuss how the Internet of Things creates many improvements to the world, increasing our convenience, health and safety, while at the same time improving energy efficiency and comfort (ercim).

Ibeacon is a new technology which helps to companies to communicate with people indoors. When start using a new technologic tools such as Ibeacon, some problems can be occurred. For using Ibeacon, there are some steps before the start. Firstly, customers have to turn on Bluetooth, accept location services on the relevant app and give permission to receive indoor notifications (Business Insider, 2014). There is also minimum hardware requirement, the device should carry the Bluetooth 4.0 technology and the minimum software requirement for Apple devices iOS 7.0, and for Android devices is Android 4.3 or greater.

Created in 1994, Bluetooth technology was apprehended as a wireless alternate to data cables by exchanging data using radio broadcasts. The name Bluetooth originated from a tenth century Danish King, Harald Blatand or, in English, Harold Bluetooth (Bluetooth, 2016). Bluetooth establishes smaller, continuously connected, networks. Bluetooth 's speed and coverage range is much smaller than Wi-Fi 's, however the trade-off permits Bluetooth to function at much lower energy expenditures and link to different devices in the course of a day that is impeccable for vastly mobile devices with inadequate batteries, such as cellular phones (Gardner, 2003). Bluetooth devices consume radio waves instead of wires or cables to connect to a phone or computer. A Bluetooth artifact, like an earpiece or watch, contains a small computer chip with a Bluetooth receiver and software that enables it to easily connect. When two Bluetooth devices need to communicate with each other, they need to pair. Communication between Bluetooth devices occurs over short-range, ad hoc networks identified as piconets. A piconet is a system of devices linked using Bluetooth technology. The system arrays from two to eight paired devices. When a network is recognized, one device precedes the role of the dominant while all the other devices act as subservient. Piconets are established vigorously and repeatedly as Bluetooth devices enter and leave radio vicinity (Bluetooth, 2016).

Low cost communication technology that uses little power was the reason Bluetooth was developed. Developers wanted to be able to connect devices from different manufactures and with different purposes, such as computers from Apple and mice from Microsoft. At low cost and a secure connection. (Newstex, 2012) The design was to remove cables so that virtually

Bluetooth is another technology that has become an increasingly standard instrument for the seamless negotiation of

Under this, there are eight goals. The first goal is support for data and voice by the air protocol. Secondly, it has the ability to create ad hoc connections so that Bluetooth devices can detect the available devices surrounding them and establish connections. The third goal is the ability to withstand. Another

The development of the Internet of Things would critically depend on progress in machine-to-machine interfaces and

Body area network (BAN) has been widely researched for last few decades in variety filed from a military use to a personal healthcare system. Moreover, the development of modern network and integrated circuit (IC), and microelectromechanical systems (MEMS) technology provide easy accessibility for the public, and opens new application regime, such as Internet of things (IoT). It seems like a simple combination of these modern technologies, but it is required for deep understanding of hardware, software, signal processing, and networking technology for the effective design in the actual building process. This is because the BAN, especially the wireless environment (WBAN), the system should be designed within the limited resources such as energy, processing power, and storage. Consequently, research in BAN is focused on tackling this constrains by introducing a new design concept, creating or improving existing protocols, and specific model or algorithm for specific applications.

A number of journals, technical reports and case studies were referred in order to develop an in – depth knowledge on the concepts of this study. Firstly, this section deals with the various traditional travel time collection techniques in order to provide a comparison with the Bluetooth travel time method. Secondly, the working concepts of Bluetooth and its components are reviewed in detail. The final section reviews the application of Bluetooth technology in travel time data collection. It involves the literature on the sensitivity analysis, veracity of the travel time obtained compared to other sensors and the cost comparisons.

Future mobile applications demand novel wireless communication technologies due to new challenges as- sociated with the shortage of spectrums, low-power radio architectures, and communication security. For example, though mmWave can fulfill some of the spectrum demands, it can still struggle to meet the growing demands for higher data connectivity over a myriad of devices, e.g., Internet of Things (IoT) []. Therefore, more bands in the electromagnetic domains will be needed. Besides, in current and future wearable devices, battery lifetime is the critical design constraint that limits the sensor performance and data throughput []. In addition, security in wireless communication is another significant challenge since future mobile devices

Bluetooth has a small area of influence (area in which a particular device or network has some influence). Mostly Bluetooth is used to transfer data between personnel devices such as handsets, tablets etc. Content that is basically transferred using Bluetooth is usually small, in Mbs, such as music sounds, low quality, short videos and stuff like that.

allows designers to bring wireless applications to market in the minimum time with significantly reduced development effort and cost.

Making IoT reality there are some features that must be satisfied. Low power demand is one of them. This is particularly useful when devices have no or limited access to power sources. The device must be active on the requirement, involve occasional human or system interaction or connected to a large network of devices that cumulatively consume a lot of power. The practical implementation of this is possible when it is supported by updates to control signaling, idle and sleep mode, link adaptation, and uplink (UL) power control. Collaboration with other devices is also an alternative to decrease power consumption (Wu, Talwar, Johnsson, Himayat, & Johnson, 2011). The example is IP (Internet Protocol) stack, a light protocol that links a large number of communicating devices all over the world. Its operation required only small and battery operated embedded devices (Atzori, Iera, & Morabito, 2010).
