Abstract-In this paper, we propose a Quality of Service (QoS) method for a real time service by using priority-based packet classification method in Home Gateway (HG). A real time service is sensitive to QoS factors such as delay and jitter. On the contrary, A non-real time service is tolerant to above mentioned QoS factors. To improve QoS for the real time service, UDP is granted a high priority compared with TCP in Data Buffer Part (DBP) of HG. We analyze the expected waiting time of prioritybased packet by using queueing analysis. The result shows that a significant QoS benefit due to the reduced waiting time for the real time service.
We have experienced an explosive increase of the IoT(Internet of Things) technology based devices including smart phones and the wireless communications. Also the growing power consumption in IEEE 802.11 WLANs(Wireless LANs) driven by these dramatic increases in not only mobile users and but also wireless APs(Access Points). To reduce the power consumption, this paper proposes a wireless AP power saving algorithm, which minimizes the transmission power without decrease the transmission and carrier sense ranges. A wireless AP which is use in our algorithm checks its own original coverage periodically for whether there is a new STA(Station) or not when its transmission power is decreased. Moreover, if there are no signaling message to connect the wireless AP, it changes its operation mode Wake-up to sleep. A Result shows that the proposed AP algorithm can reduce the total power consumption of the wireless AP approximated 18% and 35% compared to the conventional wireless AP with and without the existing power saving algorithm, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
