Resumen
This article highlights the issue of participation of mobile telephone users and distribution of wireless communication networks. Multicasting is a more efficient method of supporting group communication than unicasting or broadcasting, as it allows transmission and routing of packets to multiple destination using fewer network resources. Applications of wireless multicast support group-oriented mobile commerce, military command and control, distance education, and intelligent transportation systems. Such applications require continued connectivity atomic all-or-none transactions, and secure and reliable wireless multicast. Wireless multicast is required for a range of emerging wireless applications employing group communication among mobile users. Such a ubiquitous application would require both multicast protocol and middleware support to overcome differences in bit rates, channel quality, resources, location management, reliability, and security.
