Abstract

A system and method for providing connectivity between mobile devices and access points of a network without redundant solicitation of communication by the mobile device at each access point is described. The method involves receiving a data packet at a first access point in a control group; transmitting the data packet from the first access point to the mobile device; determining if the mobile device acknowledges receipt of the data packet; responsive to determining that the mobile device failed to acknowledge receipt of the data packet, forwarding the data packet to a second access point; and transmitting the data packet from the second access point to the mobile device.
