Abstract
Instant Messaging (IM) service has drawn growing attention in current wireless networks. However, the Quality of Experience (QoE) of IM service users are instable, since the IM service is not served with dedicated channel or guaranteed bandwidth. In this paper, we adopt a Representative Service (RS) based QoE model for IM service, and propose a scheduling algorithm to provide fair QoE to IM service users. In the QoE model, the subservice that a user is currently focusing on is defined as the RS and the quality of RS, Representative Service Quality (RSQ), is considered as the QoE of an IM service user. In our scheduling algorithm, RS is estimated when several subservices are launched simultaneously, and resource allocation is done accordingly to avoid the QoE degradation due to resource insufficiency. Simulation results validate the rationality and effectiveness of the proposed algorithm, show that it outperforms classical fair scheduling algorithms.
即时通讯(IM)服务在当前的无线网络中受到越来越多的关注。但是,由于即时消息业务没有专用通道,没有带宽保证,用户的体验质量不稳定。本文采用一种基于代表性服务(RS)的即时通信服务QoE模型,提出了一种调度算法,为即时通信服务用户提供公平的QoE。在QoE模型中,将用户当前关注的子服务定义为RS,将RS的质量RSQ (Representative Service quality)视为IM服务用户的QoE。在调度算法中,我们在多个子服务同时启动时估计RS,并相应地进行资源分配,以避免由于资源不足而导致QoE下降。仿真结果验证了该算法的合理性和有效性,表明该算法优于经典的公平调度算法。
