%X Due to the dynamic topology, limited and shared bandwidth, limited battery power of the mobile ad hoc network (MANET), providing Quality of Service (QoS) routing is a challenging task in MANET. The presence of malicious nodes in the network cause an internal threat that disobey the standard and degrades the performance of well-behaved nodes significantly. However, little work has been done on quantifying the impact of internal attack on the performance of ad hoc routing protocols using dynamic key mechanism. In this paper, we focus on the impact of Byzantine attack implemented by malicious nodes on AODV routing protocol as an extension of the previous work. Here, we propose a trust model in which the trustworthiness of each node is evaluated based on trust value and remaining energy of each node. Association level of each node is estimated based on the trust value calculated. Route selection is done using the trustworthiness and performance requirement of each route which is calculated based on both link capacity and traffic requirement to achieve QoS.
