摘要：Mobile ad hoc networks (MANETs) are not favorable to centralized trust architecture and literature review provides several security framework and solutions for trust management. However, there is no unified architecture for MANET to exploit deployed security models based on trust. This study presents compelling trust architecture in which a trust based security model is superimposed with three trust models such as a low-level trust model, a medium-level trust model, and a high-level trust model based on context-aware security. The low-level trust model meets the necessary security requirements using direct observations. The medium-level trust model ensures medium security level using direct observations and recommendation messages. The high-level trust model provides a highly secured system with high complexity and computational cost. The proposed work is formulated based on the application context to determine the trust-level in geographic routing protocol. The proposed trust is fully distributed and application context dependent and dynamic in nature. The proposed multi-level trust model is integrated with Position based Opportunistic Routing (POR) Protocol that selects the trusted next hop in the routing path. The correctness of the proposed scheme is analyzed using network simulator (NS-2). Proposed work increases packet deliver ratio and throughput significantly.
