Secure Data Transmission in Mobile Networks Using Modified S-ACK Mechanism

摘要

Mobile ad hoc network is an important application in the current wifi world. There is no need of any network infrastructure. Each node acts as a transmitter that transmits the messages to the nearby nodes and receiver that receives the messages. Each node also acts as a cluster head to receive information from the virtually connected nodes. All grouped information is sent to base station. MANET is self-governing networks. The dynamic nature of MANET, where the topology is changing very rapidly and randomly. Wireless network medium used for message dispersion is prone to attack, as it is accessible by all. It is a necessity to develop a secure and efficient technique to identify cyber attackers to protect MANET from attacks. The proposed technique 'Modified S-ACK' will provide secure and efficient way of data transmission in Mobile Networks.
