An OFDMA TDD model extension of the NS-3 WiMAX module was created. The necessary background in 802.16 WiMAX standards is presented. Additions supporting OFDMA are presented along with the challenges encountered during development. The addition of an extra dimension of sub-channels required new data structures to manage allocations. This required significant changes to portions of the NS-3 WiMAX OFDM schedulers. The model was extended to use the CDMA ranging required by the OFDMA WiMAX standard. Many message structures were extended or added. The basic upload scheduler design from the NS-3 WiMAX model and the enhanced version are extended to work with the OFDMA implementation. The OFDMA model performance of various cases are compared and discussed. Possible extensions and improvements to the current model are offered.

“…We adopt the network simulator SimulX [35] that supports features that enable the design and the evaluation of future communication protocols like cross-layer interactions, multi-interface inter-working in terminals, and heterogeneous network environments. We have integrated to SimulX the IEEE 802.11 architecture [14] and the WiMAX architecture [36]. Both have been validated through simulation tests that result in well-known performances of both technologies.…”

The Next Generation Wireless Networks (NGWNs) are seemed to be heterogeneous networks based on the integration of several wireless technologies. These networks are required to achieve performances equivalent to classic wireless networks by ensuring the continuity of communications and the homogeneity of network management during horizontal and vertical handovers. This task is even more important when management services, like security and quality of service (QoS), are deployed at access technology level. In this paper, we propose a framework for heterogeneous wireless technology integration based on network architecture skeleton and a handover management mechanism. This framework optimizes the layer-2 handover procedure to achieve performances required by sensitive applications while ensuring the minimization of signaling overhead required for operated networks. As an application example, we make use of this framework to propose a heterogeneous network based on WiFi and WiMAX technologies. We present an application example of the framework using the specification of a WiFi-WiMAX network. We propose several performance evaluations based on simulation tests based on this application. The latter confirm the efficiency of handover delay optimization and the minimization of management signaling costs.
