AB  - Riverbed(OPNET) Modeler is a packet-level discrete event-driven simulator that can easily simulate complex communication protocols and large-scale networks. However, it requires a deep understanding and extensive modifications to implement a new routing algorithm using the built-in MANET(Mobile Ad-Hoc Network) framework provided by Riverbed Modeler. In this paper, we propose a TDMA(Time Division Multiple Access)-based MANET framework that can make it easier and reduce the possibility of errors in order to solve the difficulty of adding routing algorithm to Riverbed Modeler. The proposed TDMA-based MANET framework has no modules related to other basic processors, such as IP protocol, and was developed in-house to measure the basic packet latency time and packet loss rate. When the routing algorithm is modified using the proposed TDMA-based MANET framework, only the routing algorithm and header information of some packets need to be modified. Using this proposed framework, an example of a tree-type MANET using Dijkstra's algorithm was presented to confirm the measurement of packet latency time and packet loss rate.
