Abstract: A power socket which monitors an appliance event of a load includes a power sensor, a front-end signal filter, a microprocessor, and a memory electrically connected to the microprocessor. The power sensor senses a power signal induced by the appliance event of the load and accordingly generates at least one sense signal. The front-end signal filter filters the sense signal according to a filtering criteria, in which the sense signal is filtered out or passed by the front-end signal filter. The microprocessor analyzes the sense signal which is passed to identify whether the passed sense signal is in accordance with a configurable event set. A configuration action is performed through an instruction of the microprocessor when the passed sense signal is analyzed and identified in accordance with the configurable event set.

Abstract: Methods performed by a mobile node (MN) in a secured network for handoff of communication from a serving access point (AP) to a target AP are provided. In a bounded delay channel switching (BDCS) method, the MN periodically switches between a first channel and one of multiple other channels during handoff, utilizes the first channel to transmit/receive packets to/from a corresponding node (CN) via the serving AP and utilizes one of the other channels to perform the handoff procedure to the target AP. In a dual-MAC switching (DMS) method, the MN employs a first MAC (medium access control) address to transmit/receive packets to/from the serving AP and a second MAC address to perform the handoff procedure to the target AP. The BDCS and DMS methods may be used concurrently, and may be used in a secured network that complies with, e.g., the IEEE 802.11, IEEE 802.1x or IEEE 802.11i plus IEEE 802.11f standards.

Based on the selected LBSP, the load balancer reallocates network resources and dynamically arranges the load among the APs in the wireless network hotspots. This invention can be applicable to a centralized or a decentralized wireless communication system.

Abstract: A system and method for reducing call establishment delay in wireless network is provided, in which a network node establishes a call to a wireless terminal controlled by an AP via a server. The wireless terminal notifies the server of its listen interval. In the power saving mode, the wireless terminal wakes up every listen interval and listen the beacon to check whether any buffered packet for it. When the wireless terminal learns from the beacon that there are packets waiting, it communicates with the access point to retrieve them. The server records a listen time at which the wireless terminal will wake up and listen to the AP based on the listen interval. When a network node calls the wireless terminal, the server buffers the request for a time interval based on the listen time, and then sends the request to the wireless terminal.
