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.
