Abstract
A wireless network, which includes a wireless router client operable to broadcast data packets to at least one wireless server and one additional wireless client. Each client and server includes programs for determining optimum routes between them. The client also includes a program for determining if a received data packet is not addressed to it and if the packet has been sent via a new optimal route unknown to the client, and for notifying the respective server of such a new optimal route.
