In the present era Internet has changed the way of traditional essential services such as banking, transportation, power, health, and defence being operated. These operations are being replaced by cheaper, more efficient Internet-based applications. It is all because of rapid growth and success of Internet in every sector. Unfortunately with the growth of Internet, count of attacks on Internet has also increased incredibly fast. Denial-of-service attack is one of them, which poses immense threat on the availability.
