Abstract: A host device acting as a wireless hotspot can suffer poor network performance when many client devices are connected simultaneously, particularly devices with a poor connection speed. To improve network performance, the host device can identify a client device with the worst network connectivity based on wireless signal strength, a peer-to-peer (P2P) packet drop rate, and a P2P ping response time, and instruct the client device to scan the other client devices to identify the best candidate to serve as a new host device for the client device. The hotspot functionality can then be offloaded to the new host device with respect to the client device, thereby reducing the number of client devices connected directly to the main host device and improving the network performance of the client device.

Abstract: A cleaner reciprocating structure comprises a reciprocating mechanism, a water pump assembly, and a second guide assembly. During use, a reciprocating shaft is connected to a driving assembly, and the driving assembly is operated to drive the reciprocating shaft to rotate. Since a first guiding assembly is in guiding fit with a guiding portion on the reciprocating shaft, and a sleeve is connected to the first guiding assembly, the sleeve performs reciprocating movement in the length direction of the reciprocating shaft under the rotation of the reciprocating shaft. Since a plunger is connected to the sleeve, the plunger performs piston reciprocating movement in a reciprocating cavity to suck water from a first channel and discharge the water from a second channel.
