The Minimum Relative Delay First Strategy for Multipath Transmission

Multipath time-delay estimation

A transmitted and known signal is observed at the receiver through more than one path in additive noise. The problem is to estimate the number of paths and for each of them the associated attenuation and delay. It is a frequent problem in sonar, radar and geophysics. We propose an algorithm that is easy to implement, that has a reasonable computational load and seems to be able to solve the pro...

Multipath Delay Estimation for Frequency Hopping Systems

Viii. Multipath Transmission

Theoretical investigation of the use of feedback around the limiter for improving the capture conditions at the input to the limiter has led to the formulation of a simple theory that unfolds some remarkable properties hitherto unreported. Contrary to the claim of R. M. Wilmotte (1), who made the first (and apparently only) around-the-limiter feedback proposal that exists in published work, thi...

Transmission Scheduling Optimizations for Concurrent Multipath Transfer

SCTP is a general-purpose Transport Layer protocol with out-of-the-box support for multi-streaming as well as multihoming. A protocol extension, which is denoted as CMTSCTP, extends SCTP by supporting Concurrent Multipath Transfer (CMT). That is, multiple network paths are utilized simultaneously in order to improve the payload data throughput. However, dissimilar paths – i.e. paths having diff...

Minimum Energy Reliable Multipath Ad Hoc Networks

We give an edge-based mechanism to provide reliable transport services and minimize the total energy in ad hoc networks. The implementation is based on path diversification, which uses spatial diversity in the network through multipath routing, and erasure codes to provide guaranteed reliability. We use a cross-layer design where higher network layers use information about packet loss and energ...
