Trust Based Suspicious Route Categorization for Wireless Networks and its Applications to Physical Layer Attack
Authors: ,
Abstract: With the increased usage of networks, security becomes a significant issue. Owing to the open nature, the adversary corrupts the packet by injecting high level of noise, thereby keeping the channel busy so that legitimate traffic gets completely blocked resulting in packet loss at the receiver side. Although several schemes have been proposed to prevent these attacks but none of the existing works have analyzed trust based routing. Nowadays trust based routing is an effective way to prevent the physical layer attacks in wireless network. In this paper, prevention of physical layer attack has been studied by comparing trust metrics. A new scheme known as Trust based Suspicious Route Categorization (TSRC) has been proposed which identifies the misbehaving suspicious routes and it operates in two modules. In module one, the misbehaving routes are marked as suspicious based on its trust condition. In module two, the marked suspicious routes are categorized into four groups using a classifier and from the no risk group a reliable route is selected for data transmission. By simulation studies, it is observed that the proposed scheme significantly identifies suspicious routes with higher detection rate and lower false positive probability; it also achieves higher throughput and lower delay.
