The Reverse Path Join Multicast Protocol based on the Probability

摘要

This paper proposes the Reverse Path Join Multicast protocol based on the probability(RPJMPP).The RPJMPP will discover some paths which can't easily reach the target sender. The probe message won't be forwarded from the discovered paths. So the flooding is avoided. Using analysis, the complexity of RPJMPP is O(n) and the number of probes in the RPJMPP is at most the number of probe messages in the directed reverse path join (DRPJ)protocol. Through simulation, it is shown that the RPJMPP protocol reduces probe messages.
