Application of an MD1 Queuing Model to WiMAX-Based Wireless Mesh Networks : Grid Topology Case Study

Abstract EN

Wireless mesh networking is an effective approach to reach high performance in the last mile of broadband Internet access.

The mesh structure is the basic step toward providing cost-effective, dynamic, and high-bandwidth wireless connection.

In this paper, WiMAX-like wireless mesh network is considered, emphasizing the grid arrangement which is the general topology described in the literature.

To evaluate the performance of the conventional and proposed scheduling algorithms, each link is modeled using an M/D/1 queue and a virtual node concept is introduced to describe comparable performance metrics for the system.

Performance measures of the system in addition to the simulation results are assessed in terms of the network length and the arrival rates.
