This paper presents the analysis of the power consumption of data transmission with constant bit rate over 3G mobile wireless networks. Our work includes the description of the transition state machine in 3G networks, followed by the detailed energy consumption analysis and measurement results of the radio link power consumption. Based on these description and analysis, we propose power consumption...
The fast deployment of constantly higher speed wireless connectivity for mobile users has lead to a situation where the development of electronics and the battery capacities have not been able to keep up. This has lead to a situation where the batteries of mobile devices run out very quickly when for example enjoying web content. We can enable longer battery life by lowering the QoE by moving to for...
Mobile devices people carry in their pockets every day can use various means to connect to data services all around the Internet, e.g., 2G, 3G and WLAN. This has been an important development towards an easily accessible and always-on the Internet. While radio connectivity, bits rates in particular, has developed tremendously during the recent years, battery technology and electronics has not. Thus,...
Forward error corrections have taken much attention lately due the invention of the patented LT- and Raptor-codes. With these new class of forward error corrections, it is possible to encode and decode data in linear running time. Reed-Solomon however is relatively slow to calculate both on the encoding and decoding side. But Reed-Solomon has it's own benefits: it's free of patents, several implementations...
