A queuing model for distributed scheduling in IEEE 802.16 wireless mesh networks

Abstract

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.

“…Arshadi proposed in a window‐based anomaly detection method as a possible application of their findings in which they first estimated the Weibull parameters of interarrival times in each window and then checked the discrepancy of the data with a Weibull distribution with the estimated parameters and set an alarm whenever the difference is significant. A study of the capacity of IEEE 802.16 wireless networks in mesh mode by using M/G/1/L queuing model that represented each network node by incorporating the features of the standard in order to calculate the average delay and throughput in the node was presented in .…”
