Download or read book Differential Radio Link Protocol written by Jaideep Sarkar and published by . This book was released on 2005 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: New generations of wireless cellular networks, including 3G and 4G technologies, are envisaged to support more mobile users and a variety of wireless multimedia services. With an increasing demand for wireless multimedia services, the performance of TCP becomes a bottleneck as it cannot differentiate between the losses due to the nature of air as a medium and high data load on the network that leads to congestion. This misinterpretation by TCP leads to a reduction in the congestion window size thereby resulting in reduced throughput of the system. To overcome this scenario Radio Link Protocols are used at a lower layer which hides from TCP the channel related losses and effectively increases the throughput. This thesis proposes enhancements to the radio link protocol that works underneath TCP by identifying decisive frames and categorizing them as crucial and non-crucial. The fact that initial frames from the same upper layer segment can afford a few trials of retransmissions and the later frames cannot, motivates this work. The frames are treated differentially with respect to FEC coding and ARQ schemes. Specific cases of FEC and ARQ strategies are then considered and it is shown qualitatively as how the differential treatment of frames can improve the performance of the RLP and in effect that of TCP over wireless networks.

Download or read book Aeronautical Radio Communication Systems and Networks written by Dale Stacey and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Typically, there are over twenty radio systems on board the average commercial jet aircraft dealing with communication, navigation and surveillance functions. Very high frequency (VHF) air-to-ground communication is usually the main method of information and control exchange between pilot and air traffic control. Satellite and high frequency radio links are used to complement this system for long range or oceanic information exchanges. Other communications systems are required between the airline operation centre and the pilot and sometimes between the passengers and the ground. A comprehensive guide to current systems, networks and topologies, this book covers application requirements for communication and related radio-navigation and surveillance functions in aeronautical systems. There is also an insight into future possibilities as technologies progress and airspace operation and control scenarios change. Ideal for civil aviation authorities, airspace management providers and regulatory organizations, Aeronautical Radio Communication Systems and Networks will also appeal to aircraft and radio equipment manufacturers and university students studying aeronautical or electronic engineering. Key features: Provides a broad and concise look at the various communications systems on board a typical aircraft from a theoretical, system level and practical standpoint with worked examples and case studies throughout. Considers all types of aircraft from light aircraft to large commercial jets and specialised supersonic aircraft. Looks at existing airport radio communication infrastructure and proposals for new very high bandwidth radio applications within the airport environment. Provides a complete list of formulae for engineering design analysis and quick checks on system performance or interference analysis.
