In day-to-day life security has become major issues for data transmission over wired and wireless Network. Due to the transmission of valuable data over the network, security is the big issue for the information technology sector. For the data transmission in network may not be secure and is defenseless to many threats. The various security mechanisms have been incorporated in the recent times, which greatly improve the data security. In this paper, the new way of transmission, the information using a routing algorithm such as DSDV or AODV with encryption algorithm (i.e. Reverse Encryption Algorithm (REA)) improve the data security over network.
