MANET consists of spatially distributed autonomous small devices which creates a self connected environment. MANETs are originally motivated by military applications such as border surveillance and battlefield monitoring; today MANET can be used in many civilian applications, including home automation, healthcare, traffic control and habitat/environment monitoring. Basic security services of MANET include authentication, confidentiality, integrity, anonymity and availability. However, in contrast to traditional wireless networks, in MANET, physical security of sensor nodes are not granted as they are usually deployed in remote and hostile environments. Therefore, attackers can easily compromise sensor nodes and use them to degrade the network's performance.
