Partial flooding multicast routing protocol for ad-hoc wireless networks

This paper propose a new multicast protocol for ad hoc wireless networks. The scheme, named Partial Flooding, increases packet delivery ratio at high mobility speeds and high traffic rate, without increasing the control overhead. The basic principle is that, nodes will switch to flooding when link failures happen between nodes that are involved in the multicast process. At high mobility speeds link failures are expected to increase and increasing the frequency of updates is not always the ideal way. Our scheme is adaptive to high and low mobility speeds.
