The fundamental limits on channel capacity form a barrier to the sustained growth on the use of wireless networks. To cope with this, multi-path communication solutions provide a promising means to improve reliability and boost Quality of Service (QoS) in areas that are covered by a multitude of wireless access networks. Today, little is known about how to(More)
—Current wireless channel capacities are closely approaching the theoretical limit. Hence, further capacity improvements from complex signal processing schemes may only gain modest improvements. Multi-path communication approaches, however, combine the benefits of higher performance and reliability by exploiting the concurrent usage of multiple(More)
Many of today's wireless networks have already closely approached the Shannon limit on channel capacity. A powerful alternative to increase the overall data rate then becomes one in which multiple, likely different, networks are used concurrently. The concurrent use of multiple networks simultaneously has opened up enormous possibilities for increasing(More)
—We study the performance of FTP file transfers over a WLAN and propose a new analytic model that translates the highly complex dynamics of the FTP/TCP/IP/MAC-stack, and their interactions, into a single parameter, called the effective load, and use this to describe the flow-level behavior of FTP-based file transfers over WLANs without admission control as(More)
The management of heterogeneous and hybrid networks has been always a challenge for network operators. Different frameworks and architectural approaches have been proposed and investigated in the literature. The purpose of this paper is to present the evaluation results of an integrated network management solution for the provisioning and maintenance of IP(More)
