    摘要:

    提出了一种基于软件架构的无线网绿色节能代理系统.针对无线网络的特点，通过在代理服务端创建网内其他终端的虚拟网卡和虚拟镜像,配合针对终端移动的代理服务器切换机制与重发机制,使得无线终端在节能时快速进入休眠状态,在响应请求时快速、有效地被唤醒.该软件系统不对原有网络拓扑或硬件系统做任何改变,所以具有普适性和可移植性强的特点.该系统被实际部署到一个包括11 台有线与无线上网的计算机测试平台上.通过长时间的监测,整个网络功耗节省了超过60%,充分说明了该系统在实际应用中的经济价值.

    Abstract:

    This paper suggests the green proxy software system to keep wireless devices accessible while saving the energy. It is a system that uses a proxy server to build virtual NICs and virtual images for wireless devices in the same WLAN, so that the devices can sleep during idle time while their functionality are pretended to be carried on by the virtual image in the proxy. If a network request is sent to a device, the proxy server will wake up the device. Using this software system does not require any changes to hardware system or network topology; therefore, it has strong flexibility and universal applicability. The green proxy software system is deployed in a test bench with 11 wireless or wired computers, and real-time measurements of energy consumption are provided to sense and record the energy consumption of the system. The results show significant energy reduce that reaches 60% of the total PCs energy consumption. The economic benefit is obvious if the system is widely deployed.
