摘要： A method and apparatus are described for selecting an access point in a wireless network, including initializing a channel index, recording a received signal power and information contained in one of a beacon message and a probe request response message, calculating an access link metric for each candidate access point, the access link 13 metric being between an end device and each candidate access point on the channel indexed by the channel index responsive to the received signal power and information receiving a path metric between each candidate access point and a gateway, estimating a function using the access link metric and the path metric, selecting one of the candidate access points based on the function and establishing a connection with the selected access point. Also described is a method and apparatus for maintaining a connection with an access point.

摘要： Because packets dropped due to network congestion cannot reach the intended receiver whereas corrupted packets can still be received, the reception status of multiple packets is different for congested and non-congested paths. This difference reflects a spatial variation in the received data stream that is indicative of congestion. Network congestion detection is described that treats the reception status of sequences of multiple packets as patterns and converts the problem of congestion detection into a two-class pattern classification problem. A Support Vector Machine (SVM) classifier is trained to classify the reception status of sequences of packets as being indicative or not of network congestion. If network congestion is detected, congestion control measures can then be taken. Extensive simulations demonstrate high detection accuracy under different network parameters.
摘要翻译：因为由于网络拥塞而丢包的分组不能达到预期的接收机，而仍然可以接收到损坏的分组，所以对于拥塞和非拥塞的路径，多个分组的接收状态是不同的。该差异反映了指示拥塞的接收数据流中的空间变化。描述了将多个分组的序列的接收状态视为模式的网络拥塞检测，并将拥塞检测的问题转换为两类模式分类问题。对支持向量机（SVM）分类器进行训练，将分组序列的接收状态分类为网络拥塞的指示。如果检测到网络拥塞，则可以采取拥塞控制措施。广泛的仿真表明在不同网络参数下的高检测精度。
