  Introduction The Network Simulator 2 (NS-2) is a popular discrete event simulator target at networking research. This tool can suport simulation of TCP, routing, and MAC protocols over wired and wireless networks. Although it's possible to simulate wireless local area network (IEEE 802.11), ad hoc networks and satellites networks, ns does not provide a WiMAX module. This project implements a WiMAX module based on the IEEE 802.16 standard for the ns-2 simulator, release 2.28. The focus of this implementation is the MAC layer and its mechanisms for bandwidth allocation and QoS support. The module implements the 802.16 five service flow types and their bandwidth request/grant mechanisms; moreover, it allows users to configure the QoS requirements of applications. Service flows are modeled by finite sate machines that capture how each service type react to different events. This module supports TDD mode and PMP topology. The wireless channel available in the ns-2 simulator is used. T...

  UM-OLSR UM-OLSR is an implementation of the OLSR (Optimized Link State Routing) protocol for the  ns-2 Network Simulator . The code is released under the terms of the GNU General Public License ( GPL ). Due to lack of time this project is not maintained by myself any more, feel free to take over the task of maintenance if you are interested. UM-OLSR complies with IETF RFC 3626 and supports all core functionalities of OLSR plus the link-layer feedback option. The software has been successfully tested on ns-2, and patches for several versions of the simulator are provided. It is widely employed by the wireless communications research community, as the high number of references in research papers reveal. In addition, it was ported to ns-3 by Gustavo Carneiro (INESC Porto) and to Omnet++ by Alfonso Ariza (Universidad de Málaga). Thus, you can also run OLSR simulations in modern network simulators.        Features Compliant with core OLSR (as described in RFC ...
