If the LAN interface on router is displaying high value of broadcast, how could I identify which particular IP is source for that broadcast

You can snif a LAN interface of the switch the Router is connected to.

Make sure you sniff in the same VLAN eq broadcastdomain here. If you realy experience a high volume of broadcast from just One host (not likely), it should be visible this way.

Hi

If your physical layer is ok, please verify the CPU of your switches and routers.

Routers with higher cpu utilization (above 95%) sometimes can drop or delay packets.

also make sure that stp is running on all the switches and unplug the hub for a while.
