A mobile ad hoc network (MANET) is a self-organizing, self-configuring confederation of wireless systems. MANET devices join and leave the network asynchronously at will, and there are no predefined clients or server. The dynamic topologies, mobile communications structure, decentralized control, and anonymity creates many challenges to the security of systems and network infrastructure in a MANET environment. Consequently, this extreme form of dynamic and distributed model requires a revaluation of conventional approaches to security enforcements. In this paper, we propose a new routing mechanism to combat the common selective packet dropping attack. Associations between nodes are used to identify and isolate the malicious nodes. Simulation results show the effectiveness of our scheme compared with conventional scheme.
