EAACK - A SECURE INTRUSION DETECTION SYSTEM FOR MANETS

ABSTRACT MANET consists of wireless mobile nodes that form a temporary network without the aid fixed infrastructure or central administration. Nodes can communicate directly to other nodes within their transmission range. Nodes outside the transmission range are communicated via intermediate nodes such that it forms a multihop scenario. In multi-hop transmission, a packet is forwarded from one node to another, until it reaches the destination with the help of using routing protocol. For proper functioning of the network, cooperation between nodes is required. Here, cooperation refers to performing the network functions collectively by nodes for benefit of other nodes. But because of open infrastructure and mobility of nodes, noncooperation may occur which can severely degrade the performance of networks.
