Power loading: Candidate for future WLANs?

Oscar Punal, Humberto Escudero, James Gross
2012 2012 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM)  
In this work we focus on power adaptation (power loading). Besides physical layer performance analysis, we account for protocol overhead and for practical implementation issues in WLANs.  ...  We show that pure power loading provides only a modest performance gain compared to static schemes and propose power loading combined with the deactivation of highly attenuated subcarriers as a candidate  ...  Hence, we propose power loading combined with subcarrier switch off as a solid candidate for improving the performance of WLANs.  ...

Channel Assignment and Load Distribution in a Power-Managed Wlan

Mohamad Haidar, Robert Akl, Hussain Al-Rizzo, Yupo Chan
2007 2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications  
For a Wireless Local Area Network (WLAN), we propose an algorithm based on power management of Access Points (APs) to improve load distribution and provide an improved channel assignment.  ...  The transmitted power of the data packets is not altered thus avoiding auto-rating. The algorithm then determines a user assignment that distributes the load efficiently.  ...  We consider a user to be a candidate for association with an AP if the power received by that user exceeds a given threshold. One user may become a candidate for association with several APs.  ...

Green WLANs: On-Demand WLAN Infrastructures

Amit P. Jardosh, Konstantina Papagiannaki, Elizabeth M. Belding, Kevin C. Almeroth, Gianluca Iannaccone, Bapi Vinnakota
2008 Journal on spesial topics in mobile networks and applications  
In our experiments, SEAR reduces power consumption to 46%. Using our results we discuss several interesting problems that open future directions of research in RoD WLANs.  ...  RoD strategies power on or off WLAN APs dynamically, based on the volume and location of user demand.  ...  In other words, on one hand, a highly redundant WLAN with several layers of overlapping coverage that is not utilized thoroughly is a candidate for higher power savings.  ...

Power-Saving Schedulers for a WLAN With Task-Linking Topology Awareness

Jung Hyon Jun, Young-Choi Choi, Saewoong Bahk
2007 IEEE Transactions on Vehicular Technology
