Multipath TCP is a recent TCP extension that enables multihomed hosts like smartphones to send and receive data over multiple interfaces. Despite the growing interest in this new extension, little is known about its behavior in real networks. We analyze a five-month trace collected on multipath-tcp.org using Multipath TCP. This first detailed study of real Multipath TCP traffic reveals several ...

This thesis develops new routing methods for large-scale, packet-switched data networks such as the Internet. The methods developed increase network performance by considering routing approaches that take advantage of more available network resources than do current methods. Two approaches are explored: dynamic metric and multipath routing. Dynamic metric routing provides paths that change dyna...

In recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...

Global navigation satellite system (GNSS) is designed to serve both civilian and military applications. However, the GNSS performance suffers from several errors, such as ionosphere delay, troposphere delay, ephemeris error, and receiver noise and multipath. Among these errors, the multipath is one of the most unpredictable error sources in high-accuracy navigation. This paper applies a modifie...

Line-of-sight (LOS) delay estimation in multipath scenarios is a central problem in global navigation satellite systems (GNSS). Deterministic channel models can be used to describe the multipath environment, but this usually requires the estimation of several nuisance parameters. In order to avoid this effort, stochastic channel models can be used. In this case the multipath statistics have to ...

Recently, adding multipath capability in the Internet protocol suite has attracted increasing interest. By letting end hosts discover several paths to communicate, end-to-end multipath protocols aim to improve utilization rate of Internet resources. Although many proposals for end-to-end multipath communication exist, they have not reached significant deployment. Since the multipath protocols a...

The central question of this paper is: can we enhance the spectral purity of nonlinear circuits by using polyphase multipath circuits? The basic idea behind polyphase multipath circuits is to split the nonlinear circuits into two or more paths and exploit phase differences between these paths to cancel undesired distortion products. It turns out that it is very well possible to use polyphase mu...

Multipath is one of the most dominant sources of errors in Global Navigation Satellite Systems (GNSS). In this paper we present two tracking structures with multiple gate delays and compare their performance with the performance of Narrow Correlator and High Resolution Correlator. The performance criteria are based on the Multipath Error Envelopes (MEEs), the Root Mean Square Errors (RMSEs) and...
