Current TCP protocols have lower throughput performance in satellite networks mainly due to the effects of long propagation delays and high link error rates. In this paper, a new congestion control scheme called TCP-Peach is introduced for satellite networks. TCP-Peach is composed of two new algorithms, namely Sudden Start and Rapid Recovery, as well as the(More)
—The software defined networking (SDN) paradigm promises to dramatically simplify network configuration and resource management. Such features are extremely valuable to network operators and therefore, the industrial (besides the academic) research and development community is paying increasing attention to SDN. Although wireless equipment manufacturers are(More)
1. APPLICATION SCENARIO AND DESIGN CHALLENGES Sensor networks are commonly deployed to monitor natural phenomena in the physical world. The sink uses data collected by sensors to build a map of the spatial propagation or the temporal evolution of the phenomenon under study. Recently, it has been observed that, even under normal operating conditions, data(More)
— Body area networks (BANs) promise to enable revolutionary biomedical applications by wirelessly interconnecting devices implanted or worn by humans. However, BAN wireless communications based on radio-frequency (RF) electromagnetic waves suffer from poor propagation of signals in body tissues, which leads to high levels of attenuation. In addition,(More)
