Transmission over wireless ad hoc networks is a challenging problem, because the wireless channel is characterized by limited bandwidth, multihop connectivity, mobility of nodes, and dynamically varying network topology. Current unipath routing protocols result in performance degradation in mobile networks due to unreliability of the wireless infrastructure and mobility of nodes. Multipath rout...

Multipath is among the major sources of errors in precise positioning using GPS and continues to be extensively studied. Two Fast Fourier Transform (FFT)-based detectors are presented in this paper as GPS multipath detection techniques. The detectors are formulated as binary hypothesis tests under the assumption that the multipath exists for a sufficient time frame that allows its detection bas...

Motivated by multipath routing, we introduce a multi-connected variant of spanners. For that purpose we introduce the p-multipath cost between two nodes u and v as the minimum weight of a collection of p internally vertex-disjoint paths between u and v. Given a weighted graph G, a subgraph H is a p-multipath s-spanner if for all u, v, the p-multipath cost between u and v in H is at most s times...

Multipath streaming is used by resource intensive applications to stream their data over multiple, disjoint paths, thereby cumulating the resources of the different subpaths. The trend towards application-layer implementations of communication protocols allows the deployment of a multipath streaming protocol in the current Internet. However, because resource availability fluctuates in the Inter...

Multipath TCP[31] is a recent TCP extension being developed within the MPTCP workgroup of the Internet Engineering Task Force. Multipath TCP enables a TCP connection to exchange data over different interfaces. This extension has recently received a growing interest from both researchers who publish a growing number of articles on the topic and the vendors since Apple has decided to use Multipat...

Many multipath routing schemes have recently been proposed to improve the performance of wireless networks. Multipath routing is helpful for reducing end-to-end delay, for distributing the load among paths and also for increasing the throughput. However, multipath routing is not always efficient in terms of delay as, mutual interference between multiple paths may degrade the performance of rout...

model, a RAKE receiver can be used to detect the signal from the multipath fading channel. the tap weights were assumed known when deriving RAKE receiver, but in practice a correlator is used to estimate the tap weights. Multipath fading is one of the major practical concernS in communications. Multipath problem always exists in mobile environment, especially for m~ bile unit which is often emb...

A blind joint estimator for multipath diversity and PN code timing error is proposed in this paper for direct-sequence spread-spectrum signaling on a frequency-selective fading channel. In the multipath diversity combiner, a modi ed known modulus adaptive (KMA) algorithm is used to cope with time-varyingmultipath e ects and to perform multipath diversity combining in the blind mode. In the code...

Concurrent multipath transport layer mechanisms have gained recently increasing interest in research and standardization because of the potential for bandwidth aggregation, load balancing and increased reliability. Multihomed end devices may benefit from IP-based multipath protocols like Multipath TCP or Concurrent Multipath Transmission via SCTP. In the future, concurrent multipath transport m...
