Bluetooth Information Exchange Network

Bluetooth Information Exchange Network Review



Bluetooth is a low cost and low power wireless technology for connecting portable and / or fixed Bluetooth enabled devices to form short-range wireless ad hoc personal area networks (PANs). As the Bluetooth specification does not specify a protocol to form ad hoc Bluetooth networks, a method for forming an efficient Bluetooth network under a practical networking scenario is still an open research problem. This work introduces an approach to implement an indoor ad hoc Bluetooth wireless network, Bluetooth information exchange network (BIEN). A set of Bluetooth enabled devices are able to spontaneously establish a dynamic multi-hop wireless network using Bluetooth technology without the need of formal network infrastructure. This work is an attempt at implementation of a distributed multi-hop scatternet with an integrated routing in the practical environments, while most of the literature focuses on covering the modelling of it. It intends to demonstrate how Bluetooth technology with Java technology can be used to design, develop and deploy ad hoc wireless networks, and examine how well Bluetooth technology supports ad hoc multi-hop network technology.

iPhone External Accessory Programming Exercises

iPhone External Accessory Programming Exercises Review



Here you will find, step-by-step, how you can write iPhone or iPod Touch code, in Objective-C 2.0, to access an external accessory. You will do so by using the ExternalAccessory Framework.

The ExternalAccessory Framework, introduced with iPhone OS 3.0, provides a set of classes so that iPhone and iPod Touch applications can find, and communicate with, external accessories.

An external accessory is a device external to the iPhone or iPod Touch. The external accessory connects to the iPhone or iPod Touch in one of two ways:

1. Using the external connector (the same USB connector you use to charge your device).

2. Using the Bluetooth wireless connection.

The classes that make up the ExternalAccessory framework include:

- EAAccessoryManager. The external accessory manager class. You will use this class to access the external accessory manager.

- EAAccessory. The external accessory class. You will use this class to access the external accessories properties.

- EASession. The external accessory session class. You will use this class to create an input and output stream between your application and the external accessory.

As you will see, there are five major tasks that your application must do to communicate with an external accessory:

1. Gain access to the external accessory manager.
2. Get a list of external accessories from the external accessories manager.
3. Check the accessory properties for each accessory in the list, to find the desired accessory.
4. Create a session with a specific protocol with the accessory.
5. Stream data to/from the accessory.

How can you learn to write external accessory code before having access to an actual external accessory? The answer is that the iPhone simulator includes a simulation of two external accessories, hence you can perform the exercises here even if you do not have access to a real external accessory.

CONTENTS

0. Introduction
1. Step 1. Create New Xcode Project
2. Step 2. Add Framework Header File
3. Step 3. Add Framework Reference
4. Step 4. Access EAAccessoryManager
5. Step 5. Get Array of Connected Accessories
6. Step 6. Display Accessory Properties

GPS For Newbies! (115 Pages) AAA+++

GPS For Newbies! (115 Pages) AAA+++ Review



GPS design is based partly on ground-based radio navigation systems developed in the early 1940’s that were used in World War II. These systems were named LORAN and Decca Navigator and were focused on knowing where the enemy was so they could either attack or retreat depending on the size of the forces.

Additional inspiration for modern day GPS systems came when Sputnik was launched by the Soviet Union in 1957. A team of scientists monitored Sputnik’s radio transmissions and discovered that because of the Doppler Effect, the frequency of the signal being transmitted was high as the satellite approached and lower as it moved away. The Doppler Effect is the change in frequency and wave length of a wave as it is perceived by an observer moving relative to the source of the waves.

This team of scientists that was observing Sputnik’s radio transmissions soon realized that since they knew their exact location on the globe, they could pin point where the satellite was along its orbit by measuring the Doppler distortion. This was groundbreaking and very exciting for the military at the time.

The United States Navy used the first satellite navigation system called Transit. It was first successfully test in 1960 and was quite mind-boggling for everyone in the military. When the Navy tested Transit, they did so hoping for some quite specific results. Using a constellation of five satellites, they found that the system could provide a navigational fix approximately once per hour.

In 1967, the Navy developed the Timation satellite which proved the ability to place accurate clocks in space. This is a technology that the GPS system relies on. In the 1970’s, the ground-based Omega Navigation System, based on signal phase comparison, became the first world-wide radio navigation system.

In February of 1978, the first experimental Block-I GPS satellite was launched into space and the development of modern-day GPS systems began. These original satellites were initially made by Rockwell International. Now, the satellites we use for GPS are manufactured by Lockheed Martin.

By 1985, ten more experimental Block-I satellites had been launched into space to validate the concept of GPS and in 1989; the first modern Block-II satellite was launched. By December of 1993, the GPS system achieve initial operational capability and just a month later, a complete constellation of 24 satellites were in orbit with full operational capability declared by NAVSTAR in April of 1995.

A year after that, President Bill Clinton realized the importance of GPS to civilian users as well as military users which prompted him to issue a policy directive that declared GPS to be a dual-use system meaning civilian as well as military. He established an Interagency GPS Executive Board that was responsible for managing GPS as an asset of the United States. the previous examples going off in all directions. So instead of a series of circles, you get a series of spheres.

The auto GPS system, or the vehicle global positioning system is a unique magnetic piece of advanced technology that makes use of a regional map fed into the electronic guide and fitted either on the dashboard of a car or under the carriage to act as a driver’s navigational aid when on the road. It gives directions to the destination point and how to best reach it safely, in time and with a choice of alternate routes, landmarks to cross and distances covered besides also acting as an anti-theft device and helping the owner locate the vehicle if he’s forgotten where he parked it! Now, life doesn’t get better than that, does it?
