Multipath Routing for video-streaming services over IEEE 802.1le Ad hoc Networks

Abstract

Mobile Ad hoc NETworks (MANETs) are nowadays being used much more than some years ago. One of the major reasons is the increasing number of devices that have risen lately capable of forming part of such networks. This situation makes feasible the development of new services. Especially, videostreaming is one of the most successful services demanded by the customers. In this paper we propose a QoS-aware multipath DSR-based (Dynamic Source Routing) routing protocol which helps to improve the reliability of the connections while balancing the load and decreasing the end-to-end delay. Several multipath routing designs have been evaluated seeking to get better global performance of the network. Besides, we propose a QoS-aware architecture that includes a cross-layer scheme in which a network layer scheduler manages different priority traffics and operates according to the IEEE 802.11e MAC (Medium Access Control) layer. Extensive simulations have been carried out to show the benefits of our scheme in providing different levels of QoS, including user-level QoS parameters.

QoS Oriented Cross-synch Routing Protocol for Event Driven, Mission-critical Communication Over MANET: Q-CSRPM

“…A design of cross-layer framework between application and MAC and between MAC and transport layer was proposed in [28]. Authors [29] emphasized on developing a joint optimization model in between MAC layer and the application layer that enabled mapping of video frames on the basis of its priority and network traffic load. To augment QoS provision and reliable communication, authors [29] developed a multipath DSR-based routing protocol.…”

Polynomial time algorithm for constructing vertex-disjoint paths in transposition graphs

“…More concretely, we © 2009 Wiley Periodicals, Inc. consider a problem of connecting a given source vertex s and a set of destination vertices D by a set of vertex-disjoint paths, where two paths are said to be vertex-disjoint if they share no common vertices except for the end vertices. The problem of constructing vertex-disjoint paths is particularly important in network communications [4], since it plays an important role to guarantee the quality of the routing performance in realtime network services [5,7], and to achieve a short download time in parallel downloading systems with several servers. In the literature, a number of vertex-disjoint paths algorithms have been proposed for several classes of graphs, such as star graphs [3,8] and (n, k)-star graphs [11], hierarchical cubic graphs [6], special graphs with fixed clique-width [9], and circular arc graphs [12].…”
