“…The IEEE 802.16 standard is a Layer 1 and Layer 2 protocol, so it does not specify how the traffic will be routed in the mesh topology. In centralized scheduling-based research works [11][12][13][14][15][16], different scheduling and routing mechanisms were proposed to improve the performance by lowering the interference of routes and reducing the congestion near the hotspot of the BS. However, longer path introduces more link consumption, which further causes a significant decrease in network utilization.…”

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.

“…Since all the control and data packets need to go through the BS, the scheduling procedure is effortless, but a longer path in the Mesh network is inevitable. In centralized scheduling-based research works [3] [14], different scheduling and routing mechanisms were proposed to improve the performance by lowering the interference of routes and reducing the congestion near the hotspot of the BS. However, longer path creates more link consumption, which further causes a significant decrease in network utilization.…”

Due to current advances in technology, broadband wireless networks are increasing in popularity. For large area network deployment, IEEE 802.16 mesh networks can provide a wide area, high speed and high quality multimedia service. IEEE 802.16 mesh configuration eliminates the need to have a direct link between subscriber stations (SSs) and the base station (BS) and a node can choose the links and path of the highest quality to transmit data and avoid the congested area. To provide a better QoS service over the 802.16 network, layer 3 (L3) and layer 2 (L2) QoS services must be integrated. Therefore, cross-layer mechanisms were designed in our previously proposed IEEE 802.16 QoS frameworks. To compare and identify our proposed cross-layer scheme to traditional two scheduling schemes is a very important part for performance evaluation, so this paper tries to address more simulation to identify the difference. The result of the performance evaluation also demonstrates that our proposed framework scheme has higher throughput, lower delay and signal cost than comparable systems.

“…Previous technologies, such as 802.11 WiFi, do not provide for sufficiently large coverage areas to be feasible in rural area deployments. This is a gap that 802.16e based networks promise to fill [4]. Also, for deployments alongside railroad tracks it is very important to achieve as large a coverage per location as possible in order to make it an economically viable solution.…”

Abstract-Throughput vs. distance analysis and coverage requirements are critical issues in planning wireless network deployments. With the recent availability of IEEE 802.16e and its promise of larger coverage areas for high-speed data communication, evaluating it in a real-world environment is very important to us in our ongoing study of standards based wireless technologies for the Federal Railroad Administration (FRA). In this paper, we present results obtained with our IEEE 802.16e module for NS-2, particularly throughput vs. distance performance, and its consideration for designing a real-world multi-hop IEEE 802.16e testbed. Firstly, a quantitative analysis of throughput vs. distance performance is conducted via extensive simulation, and the optimal modulation and coding scheme as well as channel bandwidth profiles are identified for specific distances. Secondly, we present a real-world multi-hop IEEE 802.16e testbed design intended for installation along BNSF Railway track in Nebraska. We apply our findings towards selecting various base station deployment locations and their appropriate communications parameters in order achieve best possible multi-hop throughput performance. We also provide a client access coverage analysis for the various locations.Index Terms-IEEE 802.16e Wireless Networks, Railroad Mobile Multi-hop Test Bed.
