I'd wait a day before trying again. they may be having problems with the files at their end.

Finally i solved my problem and would like to share it with you friends as i think it is a best linux forum which i can find.

I did the following as per your advise.

yum clean all
yum make cache
yum update

It Doesnt Work for me.

but solved the problem after that i edit /etc/yum.conf
and add the

http_caching=packages

'packages' means that only RPM package downloads should be cached (but not repository metadata downloads).
then run:

yum clean metadate
yum update

my yum.conf look like this:

[main]
cachedir=/var/cache/yum
http_caching=packages
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
metadata_expire=1800
