Evaluation of WiMAX Technology in Smart Grid Communications
In this paper, the authors propose a design of IEEE 802.16 Worldwide interoperability for Microwave Access (WiMAX) network to serve as a wireless communication platform for the smart grid. The grid traffic is classified into five priority classes. The traffic then is scheduled using three scheduling algorithms namely; Class-Based Weighted Fair Queuing (CB-WFQ), Class-Based Deficit Weighted Round-Robin (CB-DWRR) and class-Based Strict Priority Queuing (CB-SPQ) scheduling. Simulation results show that no more than 450 smart grid devices should be used to satisfy the delay requirement of class 1 and class 2.
