"Now-a-days, security in Mobile Ad-hoc NETwork (MANET) is very important issue. Due to dynamic topology and mobility of nodes, Mobile Ad hoc Networks are more vulnerable to security attacks than conventional wired and wireless network. Nodes of Mobile Ad hoc Network communicate directly without any central base station. That means in ad hoc network, infrastructure is not required for establishing communication. Mobile Ad-hoc NETwork (MANET) is different than Wireless Sensor Network (WSN). Mobile ad hoc network is more vulnerable than WSN. Therefore, attacks in MANETs are very frequent than other networks."
