We have a Voting Poll system on our website where any site visitor can vote.
we want to make sure that he does not cheat by submitting his vote multiple
time or in any others ways.
We suggested that the visitor should be registered member of the site, this
can control fraud voting. But we are not happy with this idea of registered
user.
Can any one suggest any mechanism to avoid fraud voting?

You could always check their IP address.
When someone votes you write that away. However most people wont have
static IP addresses but it would stop someone submitting multiple votes in
the same session.

Having the user log in is the only sure way you can guarantee no cheating.
Dynamic IP addresses can change fairly frequently, and some people share IP
addresses through proxy servers & such so this will not stop someone who is
determined to cheat.
You can use cookies, but people can delete cookies and/or disable them so it
is not perfect either.

Well you can verify the person's identity in any number of ways if they have
an account with you.
You can use cookies and compare names, email address, IP addresses, phone
numbers, etc. with existing user accounts to help prevent multiple accounts
being created by the same person.
