Probabilistic trust management in wireless communication system

Wireless communication system consists of wireless communicating entities that transmit data through bandwidth flexibly and conveniently. Wireless entities have the freedom to change their position which implies wireless communications support mobility in the system. With such benefits, wireless communication systems are challenged by many security issues. In this paper, we have prevented malicious behaviour of compromised communicating entity or any other malevolent entity to disrupt the communication system with our probabilistic approach of trust based security management. We have proposed Probabilistic Trust Management (PTM) in wireless communication system with consideration of current and previous interactions along with indirect evaluations depending on timing constraint. Our simulation results show the efficiency of proposed PTM in wireless communication system.
