In this paper, we investigate the use of Aspect-Oriented Programming (AOP) [13] in the domain of Mobile Ad-hoc NETworks (MANETs). More precisely we study the availability issues in Proactive routing protocols. This paper classifies the different possible attacks and examines the countermeasures to ensure availability. Our approach is based on a detection-reaction process. The reasoning followed by the detection process is built on a formal description of normal and incorrect node behaviors. This model allows us to derive security properties. These properties are woven into our implementation using the AOP. Our algorithm checks if these security properties are violated. If they are, detection of incorrect (malicious) behaviors occurs to allow the normal node to find a path without incorrect node behavior. Therefore the detector node sends to its neighborhood the detection information to allow its neighbors to avoid choosing the intruder as a node to cross to. A node chooses the path using its local diagnosis and the reputation of other nodes. Using a field in the standard control message to communicate the detections, our approach does not change the message format, so it is very easy to use and there is no overhead. While we use OLSR as an example of protocol for our studies, we argue that the presented techniques apply equally to any proactive routing protocol for MANETs.
