Main aim of the author's paper is to send and receive packets without any problems such as hacking, congestion, traffic, overloading etc., There are many techniques were introduced to avoid these above problems; in this paper, in existing system he introduced mix networks to avoid congestion problem. The major disadvantage of this mix network is introducement of various mix networks if the previous mix overloads. This effect caused the increased size of networks into larger one with the insertion of various nodes. And also he use encryption and decryption (Key generation) process for security purposes. So in the proposed system (future enhancement), he eliminate the introducement of Mix nodes.
