Energy consumption is a concern with mobile de-vices nowadays. Network interfaces are among the most power hungry components in these devices. In this paper, we describe the design and implementation of a client-centric protocol for energy efficiency. Inspired by earlier work, our protocol works by exploiting the TCP flow-control mechanism to shape incoming traffic into bursts in order to utilize...
Providing effective means of congestion control in high BDP networks represents a complex paradigm facing a variety of challenges. The landscape of such paradigm is complicated considering limited availability of congestion signaling information as well as the diverse range of utilized links including but not limited to wireless and satellite links. In this paper, the results of a performance profiling...
Most of future digital services for home and office users will be deployed and delivered through the Internet and wireless connectivity. However, employing regular access points (APs) and protocols will not allow an efficient coexistence among heterogeneous application flows. Indeed, real-time and elastic applications are (and will be) supported by different protocols and featured with different performance...
TCP is the main and most widely used transport protocol for reliable communication. Because of its widespread need, researchers have been studying and proposing new TCP variants trying to improve its behavior towards congestion to make it use the most available bandwidth while preserving a logical level of fairness towards other protocols. This paper aims at evaluating and comparing the performance...
While Transmission Control Protocol (TCP) is the most popular transport protocol used in terrestrial networks, its performance is not adequate in wireless networks with long delay, e.g., satellite networks. Though some improvements of TCP and new transport protocols have been proposed, we focus on Variable-structure congestion Control Protocol (VCP) designed for high Bandwidth Delay Product (BDP)...
In this paper the reference system is given by wireless users aboard of fast moving vehicles, such as trains, connected to the Internet by means of satellite links. Performance of several TCP flavors are investigated in this scenario and they are obtained by simulation in presence of hand-overs which happen when a train enters a tunnel and the satellite comes to be unreachable. These hand-overs imply...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
