由于来自诸如iPod和Android终端的移动的终端的高需求，IEEE 802.11无线局域网（LAN）已经被广泛部署。随着无线局域网的能量消耗的增加，结合到无线局域网中的功率节省技术的开发已经变得重要。在无线局域网中，接入点（AP）持续消耗功率，而不管通信如何。因此，我们提出了无线电按需（ROD）无线局域网，它提供了利用无线局域网的基础上的节能方案。在本研究中，我们特别着重于AP的省电机制，并提出ROD无线局域网的分散式关联管理。在我们的方案中，AP分配关联站（STA）到新的AP切换到睡眠模式之前。仿真结果表明，该方案可以实现充分的节能。
There has been widespread deployment of IEEE 802.11 wireless local area networks (LANs) because of high demand from mobile terminals, such as iPod and Android terminals. With the increasing energy consumption of the wireless LANs, the development of power saving technologies incorporated into the wireless LANs have become important. In wireless LANs, access points (APs) continuously consume the power regardless of the communication. Therefore, we have proposed the Radio-On-Demand (ROD) wireless LAN, which provides power saving schemes on the basis of the utilization of wireless LANs. In this study, we particularly focus on the power saving scheme of the APs, and propose the decentralized association management of ROD wireless LANs. In our scheme, an AP assigns associated stations (STAs) to new APs before switching to sleep mode. Simulation results show that the proposed scheme can realize sufficient power saving.
