Considerable improvements have been made towards providing ad hoc network security. However, conventional lines of defense are inefficient to put all attacks and intrusions off. In view of security limitations, we present a survey of the most relevant survivable initiatives for MANETs. Survivability is defined as the network ability to fulfill correctly its functions even in the presence of attacks or intrusions. We propose a new classification of the defense lines taking into account the resiliency-oriented approach and we identify survivability properties. Survivable initiatives are described and categorized into three groups: routing discovery, data transmission and key management. We observed that security solutions focus still on one network layer or one type of attack, using essentially preventive or reactive mechanisms.
