Multidimensional Multi-Attribute Approach to Counter the Routing Attacks on MANET

The Dynamic on demand network formation feature of MANET tend to have its biggest the vulnerability that infect the process of route establishment using routing algorithms and exploits many attacks. Identifying the attack and isolating the malicious node to reform the secured routing environment is the major goal of all researchers working for securing the MANET. IDS and trust based collaborative approach (ITCA) is the our first proposed published method which provides the platform for hybrid approach to trap the malicious nodes through combined efforts from multiple dimensions.The proposed framework utilize the benefit of Reputation and Trust based evaluation process to secure route discovery by isolating malicious nodes at early stage of route formation. The more advanced approach, multi-dimensional multi-attribute system (MDMA), incorporates multi-attribute direct, indirect trust mechanism, and use of measured risk by credibility factor, while considering indirect trust. It empowers IDS and make the ITCA more efficient. The attributes considered for calculations of trust are adaptable to change in application environment make MDMA a flexible generalized solution. The MDMA is evaluated by implementing using AODV and compared with our previous proposed method ITCA along with many other solutions. The results are better and more adaptable to the changing environment.
