A Subject Trust Management Model with Multiple Decision Factors for MANET based on Analytic Hierarchy Process

A mobile ad hoc network (MANET) is a self-organized system comprised by multiple mobile wireless nodes. Due to the openness in network topology and the absence of centralized administration in management, MANET is vulnerable to attacks from malicious nodes. In order to decrease the hazards from these malicious nodes, we incorporate the concept of trust into the MANET, and build a subject trust management model with multiple decision factors based on the analytic hierarchy process (AHP) theory-AHPStrust. Several experiments have been conducted to evaluate the efficiency of this trust management model in network interactive quality improvement and malicious node identification.
