A Survey of QoS Multicast in Ad Hoc Networks

Abstract

This survey on Quality of Service (QoS) in multicast ad hoc networks uses a framework based on the mechanisms in three important elements: resource estimations, multicast tree/mesh administration, and multicast routing. Our contribution is an exploration of the design space and an identification of areas that have not been fully explored. We discuss the design space of central mechanisms and classify proposed QoS multicast schemes according to the mechanisms they used. In addition, we summarize the scenarios used for evaluating their performance. Furthermore, we identify issues, mechanisms, and scenarios that have not been fully investigated in existing works. The paper provides a coherent understanding of design principles, conceptual operation, and evaluated scenarios of schemes designed for QoS multicast application in mobile ad hoc networks (MANETs). It also outlines new areas for future research in this field.

Evaluation of Multicast and Unicast Routing Protocols Performance for Group Communication with QoS Constraints in 802.11 Mobile Ad-hoc Networks

“…In literature, a number of review papers have been found those either separately or jointly consider multicast routing. We found that QoS multicast communications in MANETs are reviewed in [15,16,17,18]. In [15], the authors surveyed challenges in providing QoS aware multicast communication in MANET for real-time and non-real-time scenarios.…”

“…All of the above three papers have included only a portion of QoS provisioning multicast protocols in MANETs. In [18], the authors provided a detailed survey of thirtyone QoS enable multicast routing protocols for MANETs. But, the perceptions of multicasting and QoS were not much highlighted.…”

On the optimal operation of wireless networks

“…These protocols have their advantages in traditional internet, but they do not perform well in a dynamic changing wireless network environment. Studies [24,25] list challenges for supporting multicast service in mobile ad hoc networks (MANETs) and summarize multicast routing protocols designed for MANETs. In MANETs, network topology dynamically changes due to random node mobility.…”
