A confident community to secure mobile ad hoc networks

Abstract : Providing a security solution for mobile ad-hoc networks (MANETs) is not an easy task. This is due to the unique characteristics of MANETs, such as the lack of a pre- existent infrastructure, the dynamic topology of the network, the non-existence of a control authority and the constraints of device resources. In this paper, we introduce the monitoring and cluster manager modules to improve our distributed hierarchical architecture. Moreover, we study the concept of dynamic demilitarized zone (DDMZ) defined in our hierarchical architecture to avoid a single point of failure in MANETs. The DDMZ is formed by the dispensable nodes which belong to the confident community. The confident community is formed by sets of confident nodes which have high trust levels and collaborate with each other to ensure secure services. We propose a probabilistic model to define the direct connectivity between confident nodes in order to study the resistance degree of DDMZ against different attacks. Furthermore, we estimate the robustness and the availability of DDMZ and we also analyze the effects of direct connectivity and transmission range on the stability and security of the network.
