— The use of cellular systems enhanced by fixed relays has previously been proposed as a way to provide wide area coverage for high bit-rate at a reduced cost of the wireless ac...
The third-generation (3G) mobile communication systems provide great coverage, complete subscriber management and nearly universal roaming. Nevertheless, 3G systems are subject to...
Overlay Networks (ONs) are logical networks built on top of a physical network with the aim of moving part of the routing complexity to the application layer. At the same time, sen...
