Investigations on the performance of secure communication in mobile ad hoc networks

Abstract

newline Nowadays wired technology dominated the usage of wireless network. Military or Tactical Mobile Ad hoc Network (MANET), Internet based MANET, Smart Phone Ad hoc Network (SPAN) and Vehicular Ad hoc Networks (VANET) are few types of ad hoc networks. Vehicular Ad hoc Networks are used for communication between the vehicles to avoid collisions. SPAN uses Bluetooth and Wi-Fi in smart phones without the need of traditional infrastructure. IMANET is used in Persistent System s Cloud Relay. Military or traditional MANET is most commonly used in military applications to secure from attackers. During natural disasters and law enforcement operations etc., the MANET is used as rescue mission. The cellular nodes of a MANET are geared up with a Wi - fi transmitter as well as receiver which is in contact with other nodes. The contact links are wireless links and bidirectional either directly or not directly. Wireless networks maintain the mobility, even though they are capable of information communication between extraordinary parties i.e. the communication will be takes place with anonymous nodes. But the messages are limited depending on the usage of variety of sources and receivers. To solve the above issue, this research work divided as a four stages. In First stage of research work, proposed novel method of enhanced secure wireless communication in MANET, where the mixed Enhanced Adaptive Acknowledgement Scheme (EAACK) and Hybrid Encryption scheme to secure the MANET. Compared to other approach EAACK and hybrid encryption scheme used together to improve the security in MANET. The hybrid encryption scheme is the newest scheme to protect network and newline newline
