Power Control Method Based on Users and Applications QoS Priorities(UAQP) in Femtocell Network

摘要

Femtocells, also known as Home enhanced Node B (HeNB), are low cost and low power wireless Access Point (AP). This device is habitually deployed in an indoor environment to provide in-building coverage enhancement. Although femtocells are low power base stations, a vast deployment of femtocells causes many technical problems such as: interferences, user Quality of Service (QoS) and power control and consumption of femtocells. To solve such problems, most exciting works focus on power control and QoS in femtocell networks. In this paper, we provide a new intelligent QoS and power control method, denoted Users and Applications QoS Priorities (UAQP) power control method. This method aims to optimize the energy consumption of Femtocell Base Station (FBS) through adjusting their transmitting power according to two types of priorities, users and applications priorities. The simulation demonstrates the effectiveness of our proposed power control method and their performance compared to fixed power control method.
