transport is a transport-level solution that makes it possible for end hosts to use multiple access networks simultaneously. This dissertation analyzes the feasibility of using multipath transport in mobile networks. Prior studies suggest that a protocol for multipath transport requires user need, that the protocol is superior to existing solutions, and that the network has capacity. This disse...

This paper presents a method that is based on Electromagnetic Modeling (EM) technique for modelling GPS carrier phase multipath signals. A commercial software plus modules developed in-house are used for modeling and processing carrier phase multipath error parameters. Static multipath modeling experiments show that up to about 35% carrier phase errors and about 25% 3D positioning errors can be...

Abstract—This paper considers detection techniques for unresolved Ricean/Rayleigh fading multipath channels. It is wellknown that the optimal receiver has an estimator-correlator form, with a Minimum Mean-Square Error (MMSE) estimate. With known multipath delays and unknown specular phases, the Ricean non-coherent multipath channel is a case where the received noiseless signal process is non-Ga...

Mobile ad hoc networks (MANETs) faces various challenges in routing. Many routing protocols has been evaluated for better performance in terms of delays, throughputs, load balancing and congestion control in multipath routing which is widely used in MANET. The mobility of nodes allows nodes to enter and leave the network dynamically. More Attention is given to the multipath transmission capabil...

The Federal Communications Commission (FCC) mandate for locating the position of wireless 911 callers is fueling research in the area of mobile-positioning technologies. Overlapping multipath propagation is one of the main sources of mobile-positioning errors, especially in fast channel fading situations. In this paper we develop a technique for detecting and providing an estimate of the number...

In this paper, we study space-time block coding for single carrier block transmissions through frequency selective multipath channels of order L. We prove that maximum diversity of order 2(L + 1) can be achieved with two transmit and one receive antennae. We show that simple linear receiver processing can achieve full antenna diversity gains, and investigate the performance versus complexity tr...

Space-time adaptive processing is a powerful tool for interference rejection. However, its performance may significantly degrade in the presence of multipath. Due to the coherence between the multipath of the interference, adaptive methods are not able to satisfactorily remove the interference. In this paper, we present a simulation study to quantify the degradation of a common adaptive method ...

Standard TCP is the de facto reliable transfer protocol for the Internet. It is designed to establish a reliable connection using only a single network interface. However, standard TCP with single interfacing performs poorly due to intermittent node connectivity. This requires the re-establishment of connections as the IP addresses change. Multi-path TCP (MPTCP) has emerged to utilize multiple ...

Due to the constrained communication range and high density of sensor nodes in wireless sensor network, forwarding packets in sensor networks is a important field of research over the past decade. At present, multipath routing approach is widely used in wireless sensor networks to improve network performance through efficient utilization of available network resources. Accordingly, the main aim...
