Modelling Power Consumption in IEEE 802.16e WiMAX Mobile Nodes

Energy availability is the main delimiter for usage time of mobile devices. As wireless network interfaces are usually the most power-demanding subsystem in a mobile device, mechanisms for their power consumption optimization are extensively researched. However, determining the power saving gains from using such optimizations is not an easy task, specially for simulation-based analysis. This work presents an extended power consumption model for the WiMAX interface in Mobile Nodes (MN), capable of capturing minimal contributions such as signalling overhead or burst allocation geometry. Simulation results show an effectiveness comparison of discussed power consumption models.
