The attention on WiMAX and WiFi technologies are rapidly progressing and now it is common to find them not just in laptops and personal digital assistants (PDAs), but in equipment as mobile phones, parking meters, security cameras and home entertainment equipment. A combination of WiFi and WiMAX deployment, will offer more cost-effective solution than a sole WiMAX or WiFi implementation. Its technology is best meets the demand for personal broadband services. This project is focused on the performance evaluation of WiMAX and WiFi systems. It is conducted using open source simulator called NCTUns 6.0. Several scenarios have been created, to evaluate the coexistence of WiMAX and WiFi technology. The data of the simulation results have been gathered and the performance with the effects of transport layer protocol, send rates, packet sizes, distances, bandwidth and queue length were analyzed. Based on the results obtained, the performance of both WiMAX and WiFi technology are not affected due to distances variation but its performance can be improved by using of other parameter such as packet size, bandwidth and queue length.

“…To the best of our knowledge, the existing works in this context are focused only on the distributed election procedure run by nodes to access the control slots. In [12] a model is proposed for the distributed election procedure under simplified assumptions, while a simulation study was carried out in [33]. Based on these results, the interval between two consecutive accesses to the control slots can become fairly large in dense WMNs, which can eventually lead to poor network utilization.…”

Abstract-In wireless mesh networks, the end-to-end throughput of traffic flows depends on the path length, i.e., the higher the number of hops, the lower becomes the throughput. In this paper, a fair end-to-end bandwidth allocation (FEBA) algorithm is introduced to solve this problem. FEBA is implemented at the medium access control (MAC) layer of single-radio, multiple channels IEEE 802.16 mesh nodes, operated in a distributed coordinated scheduling mode. FEBA negotiates bandwidth among neighbors to assign a fair share proportional to a specified weight to each end-to-end traffic flow. This way traffic flows are served in a differentiated manner, with higher priority traffic flows being allocated more bandwidth on the average than the lower priority traffic flows. In fact, a node requests/grants bandwidth from/to its neighbors in a round-robin fashion where the amount of service depends on both the load on its different links and the priority of currently active traffic flows. If multiple channels are available, they are all shared evenly in order to increase the network capacity due to frequency reuse. The performance of FEBA is evaluated by extensive simulations. It is shown that wireless resources are shared fairly among best-effort traffic flows, while multimedia streams are provided with a differentiated service that enables quality of service.

“…Therefore, the distributed scheduling mechanism is more flexible and efficient in terms of system utilization and data transmission. Some research works [20][21][22] focused on the improvement of the throughput by modifying the original distributed access scheme, and some [23][24][25] tried to identify and model the effect of parameters in distributed scheduling for assigning different traffic types to achieve QoS support. Despite of the performance benefit of distributed scheduling over centralized scheduling, the complicated behavior of distributed scheduling makes it difficult to provide precise bandwidth allocation, which also makes it inappropriate in QoS support.…”

SUMMARY IEEE 802.16 (WiMax) technology is designed to support broadband speeds over wireless networks for the coming era of broadband wireless access (BWA). IEEE 802.16 is expected to provide transmission of high-rate and high-volume multimedia data streams for fixed and mobile applications. As an extension of point-to-multipoint (PMP) configuration, the IEEE 802.16 mesh mode provides a quicker and more flexible approach for network deployment. Multimedia networking requires quality-of-service (QoS) support, which demands elaborate mechanisms in addition to the four service types defined in the specification. By examining standard centralized and distributed scheduling/routing schemes in the mesh mode from QoS aspect, a BS-controlled and delay-sensitive scheduling/routing scheme is proposed in the paper. Associate mechanisms including admission control, flow setup and link state monitoring are also proposed. Integration of the proposed mechanisms is presented as a complete QoS framework. Simulation study has demonstrated that the average delay as well as the delay jitters per hop in the proposed scheme is smaller than that of the distributed scheme and much smaller than that of the centralized scheme. Furthermore, proposed mechanisms can also achieve higher throughput than the contrasts and generate much smaller signaling overhead, making the proposed framework a promising scheme for multimedia support in the IEEE 802.16 mesh network.
