I have already thought about this. But the problem here is, we dont have a control over neither over our DHCP server nor the system which statically configures the IP address in our subnet. I hope that, this true even with the real time deployment scenario.
So, to overcome I will that it would be better if our dhcp client does an ARP broadcast to detect an IP conflict (as per RFC 2131) and send DHCPDECLINE if it has found IP conflict.
Could you please let me know your thoughts on this.

Why aren't you able to create a reservation on the dhcp server? That is the
very very simple and _correct_ solution to this problem. This is exactly why
dhcp servers have code to allow reservations.
