The authors numerically analyze the performance of the emerging 802.16m's sleep mode operation in order to gain a new insight regarding its power consumption and traffic transmission delay when a Mobile Station (MS) in the sleep mode is served with both non-realtime and realtime traffic simultaneously. They validate the analysis via the comparison with simulation results. In IEEE 802.16 Wireless Metropolitan Area Networks (WMANs), Mobile Stations (MSs) can save their energy consumption with sleep mode when they are served with lightly loaded and/or realtime traffic. For the purpose, three types of Power Saving Classes (PSCs) are specified depending on traffic types. Accordingly, an MS in the sleep mode manages properly chosen PSC(s) for its connections according to their corresponding traffic types.
