A Review Paper on Preventing Forged Acknowledgement in Manets

MANET is a group of mobile nodes that establish themselves into a network without any predefined infrastructure or centralized operation management. Mobile ad hoc networks are advantageous in situation such as flood or earthquake. MANET can quickly be established even though the network infrastructure is unavailable. It is very hard to detect and prevent forged acknowledgement. To prevent from forged acknowledgement, detection of misbehavior nodes plays an important role in MANETs. Dynamically changing topology, limited battery power and absence of centralized control in MANETs, make them vulnerable to detection of misbehavior nodes. Intrusion Detection System (IDS) is required to detect the misbehavior nodes before they can accomplish any significant damages to the network.
