ABSTRACT

Wireless ad-hoc network is exposed easily to security vulnerabilities due to limited resources and open network structure. Routing and data transfer is performed through the flooding because of especially the mobility of nodes. The damage is huge as flooding attacks using these characteristics affect the whole network. In this paper, we propose hybrid defense mechanism that can detect RREQ flooding and data flooding attack in whole network and isolate. The amount of whole traffic of network is investigated in order to improve active detection and accuracy against attack nodes. The area-based shape which divides whole network to constant area to improve detection performance of suspicious nodes is used. The proposed method does comparative experiments with PFM, TBSS method in order to evaluate its performance and the superior performance of the proposed method is confirmed by the experiments.
