Abstract

Mobile Adhoc Networks (MANETs) play the vital role in communication. It makes one to get the complete utilization of ubiquitous computing. That is data can be accessed from anywhere at any time using any devices. As the facility by using the MANETs are increased, the complications and issues are also increased. The main support to be strengthened is security. A variety of attacks exist in MANETs. The major attack which affects any communication is the Session hijacking attack. It is a multilayer attack. But, it generally affects the transport layer exploiting transmission Control protocol (TCP). It takes away the session between the source and destination. It affects the confidentiality and the Quality Of service (QOS). The attack has several variants like Active attacks, Passive attacks and Hybrid attacks. An analysis is performed to handle these attacks. Since the MANET communications are multimedia oriented, the multimedia messages are considered for transmission and study. The QoS analyses reveal that the TLD Method performs well and minimizes the effect of the attack.
