A Proxy-based Mobile Group Membership Protocol for Large Scale and Highly Dynamic Groups

We propose a RingNet hierarchy of proxies for mobile group communications, which is a combination of logical rings and logical trees to take advantages of the simplicity of the former and the scalability of the latter. Based on the hierarchy, we propose a fault tolerant mobile group membership protocol for large scale and highly dynamic groups. Simulation studies show that the proposed protocol scales very well when the size of the network becomes large, and that it is highly resilient to failures when the node failure probability becomes large.
