I am allocating IP addr with DHCP Server to my clients with 300Sec a leased time...
I understood renewal time = 50% * leased time, hence After 150 sec i am expecting request from clients to sever for renewal....
But when i captured traffic by wireshark, DHCP request interval from client is not uniform and varying between 117sec to 147sec...
Why ? What could be the reason???

See section 4.4.5, "Reacquisition and expiration," of RFC 2131, "Dynamic Host Configuration Protocol." Two times, T1 and T2, are defined. T1 is the renewal time. It defaults to 50% of the lease time, but the server can specify a different value.
The RFC gives two reasons why the client might try to renew its lease at times that are not exactly equal to T1:
