Routing Protocols Security in Ah Hoc Networks

Mobile Ad hoc networks, also known as MANETs, are a new and useful innovation in the field of mobile wireless communication. Due to the various applications that have been and can be developed under this technology including ocean and wildlife monitoring, manufacturing machinery performance monitoring, building safety and earthquake monitoring, and many military applications, MANETs have been attracting many researchers. Unlike other types of networks, MANETs are usually deployed without a centralized control unit; the devices participating in a MANET rely on other units to route information to their destinations. This, along with the fact that MANET nodes are often constrained in power, makes MANETs vulnerable to various malicious attacks and applying the routing techniques that work with wired networks is infeasible here. In this research project we will analyze the routing protocols and security attacks in such networks. We will survey MANET routing protocols and security schema. Finally, we will propose new features to secure Ad hoc on demand Distance Vector routing protocol (AODV) against Denial of Service (DOS) attacks, and to detect malicious nodes, including black and gray holes attacks.
