As energy availability limits usage time for mobile devices, modern wireless systems implement Power Saving Mechanisms (PSMs). Determining optimal PSM parameters and switch points when applying all PSM mechanisms jointly in the same scenario is a trade-off between power savings and system performance degradation. This paper presents an unpublished performance study of the joint operation of Sleep Mode and Idle Mode on an accurate 802.16e PSM NS-2 simulation implementation, with the MS experiencing two different classes of Internet traffic, namely HTTP Web Browsing and Always-On traffic.
