“…Our algorithm takes into account several QoS parameters and heuristically seeks for a set of paths which provides the required level of QoS in a flexible and dynamic way. To cope with this, we have designed a cross-layer algorithm [6] involving parameters referred to an individual path such as mobility metric, reliability metric, available bandwidth, delay, delay jitter and losses. We also have developed a modification of the DSR (Dynamic Source Routing) protocol which is able to maintain multiple paths between source and destination and which also applies a simple and dynamic load-balancing scheme.…”

“…The proposed system to improve the performance of the video-streaming services over ad hoc networks using multipath schemes has been designed over the ns-2 simulator [5]. We have developed our modified DSR-based protocol able to search multiple routes between source and destination [6]. The IEEE 802.11 e MAC layer with its different queue priorities has also been included in the simulator [2].…”

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.

“…This scheme determines strength of the error correction code and a quantization parameter for video encoding according to the number of hops. In [15], Frias et al exploit the multipath routing protocol for scheduling prioritized video streams and best effort traffic. They schedule the traffic on the basis of the number of multiple routes.…”

This paper performs application-level QoS and user-level QoS assessment of audio-video streaming in cross-layer designed wireless ad hoc networks. In order to achieve high QoS at the user-level, we employ link quality-based routing in the network layer and media synchronization control in the application layer. We adopt three link quality-based routing protocols: OLSR-SS (Signal Strength), AODV-SS, and LQHR (Link Quality-Based Hybrid Routing). OLSR-SS is a proactive routing protocol, while AODV-SS is a reactive one. LQHR is a hybrid protocol, which is a combination of proactive and reactive routing protocols. For application-level QoS assessment, we performed computer simulation with ns-2 where an IEEE 802.11b mesh topology network with 24 nodes was assumed. We also assessed user-level QoS by a subjective experiment with 30 assessors. From the assessment results, we find AODV-SS the best for networks with long inter-node distances, while LQHR outperforms AODV-SS for short inter-node distances. In addition, we also examine characteristics of the three schemes with respect to the application-level QoS in random topology networks.
