Analysis of a Stochastic Model for Wireless Sensor Networks Submitted By: Syed Ahsan Ali Bokhari Introduction:Our aim is to develop a stochastic model of sensor networks where each sensor node is taken randomly and one after the other in sleep and active state. After analysis of the sensor model‚ we try to formulate the probability when there are many data packets in many sensor nodes. The model is analyzed in terms of energy usage‚ delay in average data and efficiency. With the increasing

Passive infrared sensor A passive infrared sensor (PIR Sensor) is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. Operating principle All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation is invisible to the human eye because it radiates at infrared wavelengths‚ but it can be detected by electronic devices designed for such a purpose

LAW TONG &AIDEN 2013/9/23 AP PHYSICS B Mr. Moss THE LAB OF ATWOOD Procedure: The purpose of this experiment was to verify the predictions of Newton’s Law for an Atwood machine‚ a simple machine constructed by hanging two different masses and from a string passing over pulleys and observing their acceleration.. Newton’s Law predicts that the acceleration should be proportional to the difference between the masses and proportional to their sum‚ where = 9.8 m/s2 is the

Motion in a Viscous Medium Aim The aim of this experiment is to measure the terminal velocity of spherical beads falling under gravity in a liquid determine‚ and hence determine its viscosity using Stoke’s law. Introduction When a stationary solid object is complete or partially immersed in a fluid‚ it experiences an upthrust or buoyant force. According to Archimedes’ principle‚ this buoyant force B is given by where ρ is the density of the fluid‚ Vs is the immersed volume of the

802.15.4 [1] for wireless communications support. The LoWPAN nodes are characterized by small size‚ constrained power‚ limited computing and storage resources. Wireless sensor network (WSN) is a subtype of LoWPAN‚ and sensor nodes can interact with their environment by sensing or controlling some physical parameters. In general‚ sensor nodes cooperate to perform a common task [2]. Some new paradigms are
