This document discusses potential research projects using the NS3 Network Simulator Tools. It lists several notable research concepts that could be explored, including SDN-based multicasting over heterogeneous cellular networks, congestion control using CC-ADOV, evaluating VANET routing protocols using SUMO and NS3, detecting jammed areas in wireless ad-hoc networks, and a QoS forwarding strategy for triple play services using Named Data Networking. It also outlines some common applications of communication projects like instant messaging, file sharing, traffic control, smart home/grid technologies, video streaming, content distribution, and health monitoring. Major NS3 models that could be modified include LTE and WiFi/WiMax models related to roaming,
