Supporting real-time traffic in a wireless network is a challenging task due to the high probability of errors and to the interference that can be provoked by other networks in the same area. There may be situations in which alien traffic is present by default and communication systems have to deal with difficulty by adapting their characteristics to provide the highest possible level of timing guarantees...
Delay/disruption tolerant networking (DTN) is a class of network techniques developed to accommodate long link delay and frequent link disruptions. Little work has been done in evaluating the effectiveness and performance of the DTN protocols when they are applied for an interplanetary Internet (IPN). In this paper, we present an experimental evaluation of Transmission Control Protocol Convergence...
Along with the rapid progress of the network technologies, as well as the vast cost decreasing of the peripherals, terminals with several interfaces have become increasingly common. Therefore, developing methods for enabling the concurrent use of available interfaces is in great demand. Although the Stream Control Transport Protocol (SCTP) has supported multi-homing feature, the simultaneous data...
In most cooperative communications works, perfect synchronization among relay nodes is assumed in order to achieve cooperative diversity. However, this assumption is not realistic due to the distributed nature of each relay node. In this paper, we propose a new distributed space-time coded transmission (DSTCT) scheme for asynchronous cooperative communications under frequency-selective channels. First,...
