The mobile networks play a vital role in the information and communication technology. There are two kinds of mobility supported by mobile networks such as host mobility and network mobility. The enhancement of Quality of Service (QoS) in NEtwork MObility (NEMO) environment is more complex than host mobility environment. One of the complexities in NEMO environment is routing of packets. The routing algorithms play a significant role in enhancing QoS. This necessitates looking into the weaknesses of existing routing algorithms. Based on the weaknesses, we have already proposed a Delay-Sensitive Routing for NEMO (DSRNEMO) to enhance the QoS in NEMO environment with respect to delay parameter. The objectives of this paper are to derive a mathematical model for DSRNEMO and to simulate the operations of DSRNEMO. The outcome of the mathematical model and simulation results show that the DSRNEMO gives better results than the existing algorithm, NEMO. Ultimately, this paper contributes to enhance the QoS in mobile networks.
