Abstract: The subject matter described herein includes methods, systems, and computer readable media for reducing Wi-Fi scanning using cellular network to Wi-Fi access point mapping information. In one exemplary method, a mobile communications device receives Wi-Fi and cellular signals and creates or obtains a database of mappings between Wi-Fi access points and cellular network information. The mobile communications device detects signals from base stations in the cellular network. The mobile communications device determines at least one recommended access point from the data derived from the database. The mobile communications device determines whether any Wi-Fi signals are present. In response to determining that at least one Wi-Fi signal is present, the mobile communications device attempts to connect to the at least one recommended access point.

Abstract: Smart devices including smart phones and tablets are getting more powerful and become versatile enough to replace conventional personal computers. Despite the rapid evolution of capabilities of such devices, controlling peripherals such as networked printers is infeasible due to lack of dedicated drivers to communicate with peripherals. To immediately enable smart devices to operate peripherals, a cloud-powered system, CloudBridge, is suggested. A CloudBridge application miming on a smart device works as a TCP bridge relaying packets between two TCP tunnels connected to a networked peripheral on one side and a cloud server on the other side. Through the bridge, issuing operations from a smart device without having drivers becomes possible by asking the cloud server to interpret the operations to a language that the peripheral can understand, CloudBridge further optimizes user experience by using data compression that is adaptively applied by a decision function.

Abstract: Receiver-based methods for controlling TCP sender behavior in cellular communications networks with large buffer sizes are disclosed. One method includes, at a TCP receiver, receiving packets from a TCP sender. The method further includes determining, based on the packets, a minimum round trip time and a moving average round trip time for cellular network carrying the packets between a TCP sender and a TCP receiver. The method further includes adaptably adjusting a received window size to advertise to the TCP sender based on the minimum round trip time and the moving average round trip time. The method further includes advertising the adjusted received window sizes to the TCP sender.
