In this paper, we present a comparative performance evaluation
of three general-purposeondemand multicast protocols, namely
ADMR, MAODV, and ODMRP, focusing on the effects of changes such
as increasing number of multicast receivers or sources, application
sending pattern, and increasing number of nodes in the network.
We use mobile networks composed of 100 or 200 nodes, with both
a single active multicast group and multiple active multicast
groups in the network, in a wide range of multicast scenarios.
Although some simulation results for these protocols have been
published before, the three protocols have not been compared,
and prior studies have focused on smaller networks using a small
set of simulation scenarios, many with only a single active
multicast group. We focus here on the effects of the protocols
relative degree of on-demand behavior and their performance in
different multicast scenarios.
