MANET is multi-hop network which is a decentralized and infrastructure-less network that includes collection of mobile nodes that are self configurable and co-operates with each other for transmission of data. It has dynamic nature in terms of topology. Due to this dynamic nature of topology and no fixed infrastructure in MANET, these nodes have to be dependent on each other for transmission of data and thus are prone to packet drop attacks like Blackhole, grayhole attack. These attacks hinder the smooth transmission of data between nodes and hampers effective communication. In this paper, a new mechanism Traffic Light Trust Based (TLTB) is proposed to detect both Blackhole attacks and Grayhole attacks. This mechanism works after modification in the standard AODV routing protocol and Watchdog mechanism. This mechanism uses color scheme to define trust level of a node or any path. Just like traffic light it includes three colors to depict the level of trust. AODV routing protocol packets are modified to include new fields for application of proposed trust mechanism. These Solutions are compared with Light-weight Trust Based (LTB) and EDRI mechanism for Normalized Control load, Packet Delivery Ratio, accuracy in Blackhole and Grayhole detection and reliability of paths.
