Providing reliable multicast is a basic requirement to build more advanced distributed protocols such as total order or leader election, and much research has gone into providing this functionality for wired networks. However, the protocols developed for wired networks tend to be unsuitable for deployment on Mobile Ad hoc NETworks (MANETs), as these do not take into account the node mobility or increased sensitivity to network load and congestion. Recently, a few reliable multicast protocols designed explicitly for MANETs have been proposed which take into account the characteristics of MANETs. This paper will given an overview of the proposed protocols and evaluate the relative merit of each.
