Application level protocols such as the Hypertext Transfer protocol (HTTP) and transport layer protocols such as Transmission Control Protocol (TCP) have performance issues on wired networks. These issues are greatly magnified by the particular conditions of satellite systems. For example, a user experiences long delays e.g. during web browsing, due to the impact that the latency of the satelli...

Introduction Europe targets to develop low-carbon and energy efficient technologies through the 2020 roadmap. On the other hand, forecast on ICT industry states an exponential increase in data traffic going through wireless cellular networks. A dense deployment of small cells (SCs) is necessary to satisfy the future traffic requirements, which results in a fast increase of energy consumption wi...

In cellular networks, conventional user association algorithms are solely based on downlink (DL) performance, which may lead to inefficient transmission power and high interference in the uplink (UL) transmission. In addition, the backhaul data rate constraint has been neglected by the majority of the existing user association algorithms. However, the backhaul constraint has become more severe ...

Massive deployment of small-cell base stations (SBSs) is going to play a key role for capacity and coverage enhancements in 5G networks. However, the backhaul for these networks remains one of the important issue to solve. Ideally, the capacity of backhaul has to be in the same order of wireless links in order to avoid bottlenecks in the delivery and sustain huge traffic generated by mobile use...

Mobile data traffic is expected to increase substantially in the coming years, with data rates 1000 times higher by 2020, having media and content as the main drivers together with a plethora of new end-user services that will challenge existing networks. Concepts and visions associated with the ICT evolution like the network society, 50 billion connected devices, Industrial Internet, Tactile I...

In this monograph, the impact of cooperation on the performance of wireless cellular systems is studied from an information-theoretic standpoint, focusing on simple formulations typically referred to as Wynertype models. Following ongoing research and standardization efforts, the text covers two main classes of cooperation strategies. The first class is cooperation at the base station (BS) leve...

FOR the potential of providing rates of multiple Giga-bps in a single channel, millimeter wave (mmWave) communications have recently attracted substantial research interest. While mmWave technology is already being used in stationary scenarios such as indoor hotspots or backhaul, it is challenging to use mmWave frequencies in mobile networks, where transmitting/receiving nodes may be moving, ch...

In this paper, we introduce the root of digital human binary coded Jong Nang communications as the wooden gate in Korea Jeju Island custom, has been using after about 1234 years. We compare the digital logic with modern traffic signal codes and analysis of both cases. Shannon channel capacity of the Jong Nang are 3 input NOR and binary erasure multiple access channel. Jong Nang communications i...
