The Implementation and Performance Analysis of Mobile Multicast in WLAN Environments

摘要

With the development of Mobile IPv6 and multicast technology, mobile multicast becomes a research hotspot. Based on two basic mobile multicast methods, the Bi-directional Tunnel (BT) method and the Remote Subscription (RS) method, some mobile multicast schemes have been proposed. However, most of them evaluate the performance by means of analysis and simulation, but lack of testing the performance in a real test-bed. So in this paper, we implemented several mobile multicast schemes and evaluated their performance in our test-bed. The experimental results show that (1) the mobility management protocols have an important impact on the BT-based methods; (2) the distribution of multicast delivery tree affects the performance of RS-based methods.
