Project Management

Introduction

Wireless systems have become an indispensable part of modern day communications, from living rooms to airplanes. While the latest technological advancements in wireless have given birth to new kinds of devices and access techniques, there is an accompanying increase in the system complexity and sophistication. Hence, measurements have become more crucial than ever to design and evaluate these complex emerging systems. While previous measurement approaches do measurements after fully building a system, there is a proposal that measurements should be the tightly integrated as the building block of system design for emerging wireless systems. The project management concepts will be explained with the help of the description related to the wireless systems implemented in the building. Therefore, all the issues related to the project management of wireless systems will be discussed in detail.

Background of the Wireless Systems

The advance of technology in electronics has enabled many people to remotely collect physically measured information with electric sensors and transform the collected data into knowledge with software. The network facilities, includes ethernet, Wi-Fi, and cellular networks, enable remote access to the data sampled by a sensor. A number of potential applications can perform such remote data collection for various purposes, including environmental monitoring, industrial sensing, battlefield awareness, surveillance, forest fire monitoring, wild exploration, remote diagnosis, and so on. As an example, a group of sensors may be deployed in a forest to sense the local humidity or detect fire in the surroundings. The data from the sensors can be wirelessly sent to a nearby station and even further delivered to a remote monitoring center through computer networks. As another example, equipped with a camera sensor and a radio transceiver, a robot may enter a hazardous area to conduct searching tasks. An additional example is in the health care field. A patient may wear a blood pressure sensor and that sensor detects his blood pressure and transmits that value to his smart phone via Bluetooth (Boukerche, 2005).

The smart phone further delivers the blood pressure reading to a remote hospital through Wi-Fi for diagnosis. An electric sensor is usually pre-programmed to detect ambient conditions. Sensors permeate our life in various forms, e.g., cameras, GPS, thermometers, and blood pressure sensors. According to its making and use, the type of information detected by the sensor varies, including but not limited to environmental attributes, states of other equipment or itself, and conditions of human body. A sensor may sense ambient humidity, record images and noises of its surroundings determine its own location, detect the voltage of an active circuit, record the heart rate of a patient, and so on. A sensor may be installed indoors, outdoors, or attached to another object including devices and human. For example, certain large buildings have a few temperature sensors installed inside; a number of earthquake sensors may be distributed in the wild; a moving robotic vehicle can integrate a GPS receiver, a radio transceiver and a camera sensor as part of its circuit board; a smart phone ...
