In Voice-over-IP, the quality of interactive conversation is important to users. Quality-based playout buffering seeks an optimum balance between delay and loss. However, such a scheme still suffers when packet losses are bursty. Path diversity can alleviate the effect of losses and improve perceived quality by providing redundancy. In this paper, a new scheme is proposed which evaluates the pe...

We study networks representing the dynamics of elementary 1D cellular automata (CA) on finite lattices. We analyze scaling behaviors of both local and global network properties as a function of system size. The scaling of the largest node in-degree is obtained analytically for a variety of CA including rules 22, 54, and 110. We further define the path diversity as a global network measure. The ...

In this paper we present new improvement ideas of the original PageRank algorithm. The first idea is to introduce an evaluation of the statistical reliability of the ranking score of each node based on the local graph property and the second one is to introduce the notion of the path diversity. The path diversity can be exploited to dynamically modify the increment value of each node in the ran...

Packet path diversity is one of the recent advances in networkadaptive video streaming. In this paper we first examine two specific techniques for video streaming that exploit diversity to achieve improved performance. The first technique uses a framework for rate-distortion optimized scheduling of the packet transmissions over the available network paths. The second technique exploits feedback...

This paper presents a scalability and load balancing study of the All-Path protocols, a family of distributed switching protocols based on path exploration. ARP-Path is the main protocol and it explores every possible path reaching from source to destination by using ARP messages, selecting the lowest latency path. Flow-Path and Bridge-Path are respectively the flow-based and bridge-based versi...

Multipath routing allows building and use of multiple paths for routing between a source-destination pair. It exploits the resource redundancy and diversity in the underlying network to provide benefits such as fault tolerance, load balancing, bandwidth aggregation, and improvement in QoS metrics such as delay. There are three elements to a multipath routing, namely, path discovery, traffic dis...

Recently, a number of empirical models have been introduced in the literature for the behavior of direct path used in the design of algorithms for RF based indoor geolocation. Frequent absence of direct path has been a major burden on the performance of these algorithms directing researchers to discover algorithms using multipath diversity. However, there is no reliable model for the behavior o...
