Location-Based Multicast in Mobile Ad Hoc Networks
Young Ko, Nitin H. Vaidya · 1998
Multicast distribution in mobile wireless networks is a topic that has recently begun to be explored. For multicasting, conventional protocols define a multicast group as a collection of hosts which register to a multicast group address. However, in this paper, we define a location-based multicast group which is based on a specific region ("Multicast Region") in a mobile ad hoc network (MANET). Hosts within the multicast region at a given time form the multicast group at that time. We present two algorithms for delivering packets to such a multicast group, and present simulation results. 1 Introduction Multicast distribution in mobile wireless networks is a topic that has recently begun to be explored [22]. When an application must send the same information to more than one destination, multicasting is often used. Multicasting has played an important role in supporting multimedia applications, such as audio/video broadcasting. Multicasting is much more advantageous than multiple unic...
