AQUINO SANTOS, Raúl; EDWARDS BLOCK, Arthur  e  GARCIA RUIZ, Miguel. A Performance Study of Multicast Routing Algorithms on Wireless Ad Hoc Networks. Comp. y Sist. [online]. 2007, vol.11, n.2, pp.105-116. ISSN 2007-9737.

This paper presents a performance analysis of topological and geographical multicast routing algorithms for mobile wireless ad hoc networks. Flooding and On-Demand Multicast Routing Protocol (ODMRP) are simulated and compared with two novels protocols proposed: Topological Multicast Routing Protocol (ToMuRo) and Geographical Multicast Routing Protocol (GeMuRo) in pedestrian and vehicular scenarios. The scenarios evaluated consider one multicast transmitter and one, two, and three multicast receivers under various mobility and transmission ranges. The behavior of 250 nodes is evaluated in terms of End to End Delay (EED), Jitter and packet delivery ratio and overhead. Results show that ToMuRo is suitable for pedestrian scenarios due to its tree-based architecture and GeMuRo is proper for vehicular scenarios because it is based on a mesh topology.
