Bluetooth Based Smart Sensor Networks

A WSN is a type of wireless networks that consists of collection sensor nodes which are tiny devices. Each sensor node of the network has different processing capability. It may contain multiple types of memory (program, data and flash memories), have a RF transceiver, have a power source (e.g., batteries and solar cells), and accommodate various sensors and actuators. The nodes communicate wirelessly and often self-organize after being deployed in an ad hoc fashion [13, 14]. Optimum need of each sensor node is to maximize its own utility function. Also the whole network requires resource assignments balance to perform in a useful and efficient way. This chapter presents a brief survey on WSNs showing its types, characterizing features, protocols and applications.

In our project, we are trying to provide an embedded wireless system by using the Army base stations can monitor the health of soldiers using wireless body area sensor networks such as temperature sensor, heart beat sensor, etc. Base stations can also track the location of soldiers by using Global positioning system (GPS)

Bluetooth is a convenient way of communication in the modern society as it has many benefits for both individuals and companies.

In order to establish a given area network, wireless communication means is used by wearable devices to transmit data to proximate devices. Data transmission must be secure since wearable devices transmit vital information. Wearable wireless communication system is exciting new frontier techniques. There are many devices worked in

Another growing section of wireless technologies is Bluetooth. Every day a new Bluetooth device is released, these devices are security nightmares for the most part. Bluetooth has been proves to have

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).

Bluetooth is named after the 10th century Viking king Harald Blatand, who conquered all of Denmark and Norway and converted the Danes to Christianity. (Aardsma, 2001) The king was known for his desire to snack on blueberries and his ability to unite the warring factions that is now known as Denmark, Norway, and Sweden. (Newstex, 2012) The idea that the blueberries caused his teeth to turn blue is not confirmed. But his ability to unite different people groups inspired the SIG to use the name “Bluetooth.”

Abstract – This paper is a report on Bluetooth wireless technology. In this report, we have included an introduction to the emerging technology, scenarios, existing research issue, problem statements, suggestions to improve and conclusion. In the introduction, we explained about what is Bluetooth, how does it communicate, and technical standards and performance levels of Bluetooth. In scenarios, we explained the applications of Bluetooth. For the existing research issue, we have included 2 researches on Bluetooth which is types of device that use Bluetooth and Bluetooth accessible services. Explanation of problems faced by users when using Bluetooth is included in the problem statement. The solution for these problems will be included in

Bluetooth is a short-range wireless technology designed to enable wireless communication between devices. It has gained popularity and acceptance in the modern world. The paper begins with a description of the technology in terms of the hardware, network infrastructure, and software. Then it addresses the related issues of interference and reliability. This analysis is followed the advantages of this technology and its role in the global third generation wireless scheme, health isseues, safety concerns, and business implications.

Wearable sensors are developed in 10-10 years ago, but sensors are wired for records processing, facts saved in facts recording unit. Stressed out networks are strong, however for person it difficult to manage large sensor network with wired and additionally hard to long data transmission. Wi-Fi transmission becomes available to triumph over the stressed out community. For quick Wi-Fi statistics transmission, some protocols are used like Zigbee, Bluetooth. Wearable sensors are help to gather the information and transmit to require area. Every wireless sensor, community has transceiver. In this wearable sensors include respiration, EDA and EMG sensor, used as wireless sensor nodes. Records transmission are in the form of single packet. The packet length and length are configurable. Capabilities are extracted from sensors outputted information. After the capabilities extraction actual outcomes of health relates are passed off. USB transducer is used to show sensor statistics in real-time on a computer monitor in the course of sensor calibration.

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.

Bluetooth and Wi-Fi are two branches of the same tree. They only differ in the way they are used. Bluetooth is used to transfer data between devices, which are placed near to each other, without the use of cables. Terminology of Wi-Fi is quite the same but the range of distance between the devices could be quite large. A typical Wi-Fi network that is being used in a household could have a range of 200m but a Wi-Fi network that is being used by a business firm could transfer data in several kilometers.

Now a Days all people like to use a technology, in this project we try to make Home appliance system which will be controlled by personal smart phone via Bluetooth. In This Paper we try to explain whole circuit, all components which we will use, and how the system works.

Wireless body area network is a type of wireless sensor network technology that has confined limits to the body of the person under observation. Being a major area of interest due to variety of advantageous applications like continuous and flexible health monitoring of patients or performance analysis of athletes etc, WBAN is one of the major and most interesting area of study of present.
