[balaji.bandi]

its all depends on the deployment : (what RP fix the issue explained below )

cisco official guide :

RP is needed for Sparse mode to work.

If you are not already too far down the path of PIM-SM and IGMPv2, you might consider PIM-SSM and IGMPv3 instead. Unlike PIM-SM, SSM does not require RPs, eliminates group address collisions and provides a modicum of security against injection of bogus multicast traffic.

Well, according to Cisco a RP is required for PIM-SM, more details here.  The details show various ways of providing the RP.

If you would additional information about PIM multicast, including PIM-SSM and IGMPv3, as mentioned by @Ramblin Tech , you might start here.
