Decreasing Transmission Power with Provisioning Quality of Experience in Mobile Communication Networks

Abstract

Mobile communication systems should be able to support multimedia traffics with limited transmit power due to the frequency reuse for maximizing the channel accommodation. Real-time data is very sensitive to delay, and they need to be transmitted instantly. On the other hand, non-real time data is less sensitive to delay, and their packet loss can be handled more flexibly. Therefore an adaptive resource management scheme is essentially required which enables to keep the minimal power allocated in the base station while guaranteeing the user requirements for QoE within a permissible range. Power-saving techniques are required in order to support multimedia services in the mobile networks because the power consumption increases greatly with the transmission rate increase. This paper proposes a novel scheme which enables to keep the allocated power minimal while guaranteeing the user requirements for QoE within a permissible range. 키워드 : 체감 품질, 자원 관리, 서비스의 질, 종단 간 QoS, 최소 전력 Key word : QoE, Resource Management, QoS, End-to-End QoS, Minimum Power Received 22 July 2016, Revised 25 July 2016, Accepted 08 September 2016 * Corresponding Author Jong-Chan Lee(E-mail:chan2000@kunsan.ac.kr, Tel:+82-063-469-4863) Department of Computer Information Engineering, Kunsan National University, Gunsan 54150, Korea Open Access http://doi.org/10.6109/jkiice.2016.20.12.2219 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
