Moversight: An approach to support mobility in collaborative applications

Increasing mobility and collaboration require novel schemes for group communication that actively support closed collaborations in mobile scenarios. Existing protocols do not sufficiently support, for instance, temporary losses of connections with the group. In this paper, we introduce Moversight, a new P2P group communication protocol, which is especially designed for closed groups in mobile scenarios with varying churn rates. It supports up to 100 mobile, nomadic, or stationary participants. Moversight applies a new group communication paradigm, called mobile optimistic virtual synchrony, to handle churn-related peer failures. We describe the basic idea of Moversight.
