The IEEE 802.16 standard for wireless broadband networks includes the mesh mode in its specifications, where network nodes interact to deliver packets from a client to a remote destination through intermediate nodes. This paper presents a study of the capacity of IEEE 802.16 wireless networks in mesh mode by using M/G/1/L queuing model that represents each network node by incorporating the features of the standard in order to calculate the average delay and throughput in the node. An iterative method integrates the calculation results at each node, obtaining the end-to-end delay from any node of the mesh to the Base Station. Because of multiple hops, a node far from the Base Station may have its flows damaged. To minimize this problem, we propose a criterion for a fair distribution of resources. We show the numerical results of the model which indicate a good fit when compared with simulation results.

Wireless mesh networks have emerged as high-performance and cost-effective approaches to extending the coverage area of wireless local networks and providing last-mile broadband Internet access. In this paper, we develop an analytical model to investigate delay, loss rate, and performance metrics of central mode of IEEE 802.16d mesh structure. Two well-known scenarios are selected for simulations: BS-centered and BS-cornered scenarios. In the first scenario, the base station is located at the center of the network; while in the second one, the base station is located at one the four corners of the network. In this analytical model, two major delay constraints namely queuing and scheduling delay which affect the end-to-end delay of the system have been considered. It has been shown that the height of the network is limited due to the constant frame duration. Meanwhile, the position of the BS is considered in the analysis. The simulations conducted to measure the average end-to-end delay confirm the results obtained by the analysis.

“…In Distributed scheduling, each node competes for channel access using a pseudorandom election algorithm based on the scheduling information of the two hop neighbors. However, the complicated behavior of Distributed scheduling makes it difficult to provide precise bandwidth allocation, which also makes it inappropriate in QoS support [22].…”

IEEE 802.16 Wireless Network technology is a hot research issue in recent years. It provides wider coverage of radio and higher speed wireless access, and Quality-of-Service plays an important part in the standard. For mobile multihop wireless network, IEEE 802.16j/MR network not only can supply large area wireless deployment, but also can provide high quality network service to mobile users. Although Mobile QoS supporting has been extensively investigated, Mobile QoS supporting in the IEEE 802.16-MR network is relatively unexplored. In this article, the probability of a mobile user who visits a Relay Station (RS) is known beforehand. With the visiting probability at each RS and the system specified size of the range for bandwidth allocation, Base Station (BS) can calculate the required bandwidth to meet the mobile user's demand and allocate appropriate bandwidth for a mobile user roaming in the range of the bandwidth allocation. The range of bandwidth allocation for mobile users is called the Zone in this article, which includes the user's current RS and the nearby RSs. The proposed scheme is therefore called Zone-based bandwidth management scheme. The simulation results demonstrate that Zone-based bandwidth management scheme can reduce QoS degradation and bandwidth re-allocation overhead.
