Abstract

Mobile stations (MS) in IEEE 802.16m network undergo frequent battery drain out with mobile Internet services due to inappropriate power saving model (PSM) and power saving class (PSC). Although, PSM models for mobile Internet based services have been available in literature, they do not converge towards the best effort traffic requirements, namely, web browsing and file transfer protocol (FTP). Hence, to conserve energy towards green communication, PSMs are developed by considering the scaling, shaping and location or threshold parameter of the web browsing and FTP traffics. With these proposed PSMs, the MS with conventional PSC suffer from high-energy consumption and response delay as the interarrival time of the traffic increases. Hence, a modified PSC is proposed for the aforementioned traffics. Although the modified PSC performs well with web browsing traffic, it needs improvement under FTP traffic. Therefore, an adaptive PSC is proposed to improve the system performance with FTP traffic. With web browsing traffic, the proposed PSC reduces the response delay and energy consumption by 79.38 and 73.26 %, respectively, than the existing PSC. Also, with FTP traffic, the proposed PSC lessens the response delay and energy consumption by 62.58 and 41.79 %, respectively, than the existing PSC.
