Mobile ad hoc network (MANET) is one of the well-known technologies in network and communication. MANET offers significant features that help to improve applications. In this paper for MANET's secure routing and improved routing protocol is introduced. The proposed routing technique is a trust-based routing protocol that evaluates the characteristics of intermediate nodes in the network. During the evaluation of nodes, a weighted trust value for all intermediate routers is calculated to create a secure path establishment. To compute weighted trust the network parameters of nodes are used i.e. packet drop ratio, RRT and energy consumption rate. Additionally, a trust threshold is used for classifying the malicious and legitimate nodes in a network path. Therefore trust threshold is used to make decisions for the selection of a secure and efficient path. Finally, a comparative study between traditional AODV and proposed trust-based AODV is performed. The experimental results demonstrate the proposed routing is efficient and secure as compared to traditional AODV routing protocol.
