与Oracle同行：通过位置感知有效使用移动网络
Walking with the Oracle: Efficient Use of Mobile Networks through Location-Awareness
摘要：
始终最佳分组交换（ABPS）是一种用于无线通信的新颖方法，其使得配备有多个网络接口卡（NIC）的移动节点能够动态地确定要使用的最合适的NIC。使用ABPS，移动节点可以无缝切换到不同的NIC，以获得更好的性能，而不会导致应用程序级别的通信中断。为了实现这一点，路由器始终保持活动状态，软件监视器不断探测可用接入点的信道。虽然这确保了最大的连接可用性，但当给定NIC没有可用的接入点时，可能会浪费大量能量。在本文中，我们解决这个问题，通过调查使用的“甲骨文”能够提供信息的网络可用性。这允许基于报告的可用性动态地打开/关闭EEPROM，从而降低功耗。我们提出了一个马尔可夫模型，使我们能够估计的Oracle上的ABPS机制的影响：结果表明，可以实现显着减少能源消耗的影响最小的连接可用性。最后，我们描述了基于Web服务和地理定位的Oracle的原型实现。
英文摘要：
Always Best Packet Switching (ABPS) is a novel approach for wireless communications that enables mobile nodes, equipped with multiple network interface cards (NICs), to dynamically determine the most appropriate NIC to use. Using ABPS, a mobile node can seamlessly switch to a different NIC in order to get better performance, without causing communication interruptions at the application level. To make this possible, NICs are kept always active and a software monitor constantly probes the channels for available access points. While this ensures maximum connection availability, considerable energy may be wasted when no access points are available for a given NIC. In this paper we address this issue by investigating the use of an "oracle" able to provide information on network availability. This allows to dynamically switch on/off NICs based on reported availability, thus reducing the power consumption. We present a Markov model which allows us to estimate the impact of the oracle on the ABPS mechanism: results show that significant reduction in energy consumption can be achieved with minimal impact on connection availability. We conclude by describing a prototype implementation of the oracle based on Web services and geolocalization.
