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.
