This paper presents an architectural model that implements the Multipath execution model of Prolog programs. Multipath performs a partial breadth-rst traversal of SLD-trees, allowing a more eecient execution than the standard depth-rst traversal. Its advantages can be exploited either in a sequential or parallel implementation. In a sequential execution, Multipath reduces the number of operatio...

Use of anycast service can considerably simplify many communication applications. Two approaches can be used for rout ing anycast packets. Single-path routing always uses the same path for anycast packets from a source, while multipath routing splits anycast traffic into several different paths. The former is simple and easy to implement, while the latter may potentially reduce congestion, impr...

This paper presents a novel multipath energy aware routing for wireless ad hoc network. A deep analysis of different routing metrics such as MBCR, MMBCR and MDR have been led out and the Minimum Drain Rate metric has been selected as energy metric to integrate in the Multipath DSR protocol. Performance comparison with an energy efficient DSR (DSR-MDR) has been presented showing the benefits of ...

GPS multipath has long been considered a major error source in GPS applications. In this paper, however, an attempt is made to use multipath as a signal. The proposed application of using GPS multipath to monitor the slope stability involves two steps. The first step is to extract multipath and to detect its change based on an adaptive filter using the leastmean-square algorithm. In the second ...

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 TCP extension, little is known about its behavior with real applications in wireless networks. This paper analyzes a trace from a SOCKS proxy serving smartphones using Multipath TCP. This first detailed study of real M...

Multipath transport is a promising new paradigm that enables the concurrent use of different paths and resource pooling of their capacity. Ongoing research and standardization activities extend the Transmission Control Protocol (TCP) towards a Multipath TCP solution. The objective of the MPTCP protocol [1] by the IETF Multipath TCP is to aggregate multiple subflows between two endpoints into a ...

in this paper, we introduce the concept of Independent Directed Acyclic Graphs (IDAGs) to achieve resilient multipath routing. The algorithm developed in this paper: (1) achieves multipath routing; (2) guarantees recovery from single link failure. The multipath routing scheme consists of an algorithm to determine a set of multiple disjoint or partially disjoint paths and a mechanism for distrib...

The performance of low-latency video streaming with multipath routing over wireless mesh networks is studied (WMN). This paper presents a novel multipath routing video delivery scheme (MRVD) in which video takes multipath to reach its destination, thereby increasing the aggregate throughput. Based on proposed multipath routing scheme, a video scheduling algorithm is proposed, which achieves hig...

In this extended abstract we present a Bayesian estimation method applicable on single-input multiple-output radio channels. In addition to specular multipath components (MPC) also the parameters of a stochastic process are estimated that comprises non-resolvable dense multipath. Exploiting the hierarchical tree structure of a Bayesian graphical model, the parametric channel estimator is able t...

Multipath propagation is a major source of degradation in the performance of conventional PN code tracking loops. The mean-square tracking error of a conventional delay-locked loop (DLL) exhibits an irreducible floor due to the presence of closely spaced multipath components. In this paper, we present a new PN code tracking algorithm that does not suffer from the presence of multipath component...
