Wireless sensor network

issues in WSNs are based upon a lot of theories and assumptions. The basic concepts of connectivity and coverage have an essential role in understanding this issue. In this section, we describe the notions of connectivity and coverage, the category of sensor nodes, sensing models and communication models. 2.1. Connectivity and coverage The objective of deploying a WSN is to keep the FoI under strict surveillance and then forward the obtained information to a designated gateway/data sink. Hence,…

referred to as IoT denotes the internetworking of physical devices with software, network connectivity and sensors that enable them to communicate. The physical devices include buildings and vehicles. These physical devices are embedded with actuators, electronics, network connectivity and sensors that enable them to collect and exchange data leading to an infrastructure of the information society. Through the sensors and internet connectivity, Internet of Things enables the remote control of…

by right sensor the robot will turn to its left and vice versa. When the robot detects the edge on both the sides it moves backward untill it doesn’t detect any edge and then moves to the right side a little and repeats the above process. Line following robot : Now, lets design a line following robot, for that, I need to pick a 50 ext block and attch 2 straight connectors to it like this. then I am going to attach both the sensors to this 50 ext block, and then I am fixing this sensors at the…

actuation. MEMS technology used in sensing applications with use of basic mechanical elements such as microcantilevers, beams, diaphragms, springs, gears and so on. In this research paper, microcantilevers are used as basic elements for design of Sensors. This paper shows the design and simulation of microcantilevers with static loads and respective variation in different parameters. Keywords— MEMS, Microcantilevers, Actuation, Sensing. I. Introduction MEMS made microsensors are used for…

A number of caries detection devices are available in the market today. Each of these is based on a certain underlying physical principle such as X- Rays, Visible light, Laser light, Electrical current and Ultrasound (Pretty, I. 2006). The four basic characteristics that need to be looked at for comparing devices are explained below. 1. Reliability Reliability ensures a procedure that is consistent, stable and dependable with minimal error on repeated measurement of the same variable (Pretty,…

Plantronics voyager Bluetooth headset When you start searching for wireless headsets on the internet, you would get confused as there are numerous options available. However, if you have the correct priorities, you would be able to choose the correct headset without any kind of problem. Once the factors which you need to hold at the highest level of importance is company reputation. If a headset brand does not have a positive image, do not consider it to buy headsets even if you are getting them…

core objectives of this lab is to understand the concept of cell association of received power (Rx) and designing a modified network planning for an LTE services using multiple eNodeBs for an indoor premises (shopping complex). We are also going to compare the noise limited and interference limited systems along with its interference synchronization in radio access network. To accomplish these objectives, we are going to perform the following tasks: 1. To expand the indoor design of LTE service…

Wifi is used all over the world. Every wonder how it was made? Hedy Lamar created frequency hopping in the 1940s which lead to wifi. She created the frequency hopping technique for the navy, but when she explained it to them they said it would never work. So Hedy Lamar gave her patent to the Navy and never earned a penny off her invention. She died at the age of eighty six and did not get much credit for her idea. Now, wifi is used everyday by millions of people. Hedy Lamar made a huge impact in…
