Abstract:
1. A method of operating wireless computing units in a wireless network system having a wireless access point (AP), the method comprising: grouping a plurality of wireless computing units into a cluster, the plurality of wireless computing units including a first wireless computing unit having the largest amount of data to transmit relative to the plurality of wireless computing units, and a second wireless computing unit having the second-largest amount of data to transmit relative to the plurality of wireless computing units; designating the first wireless computing unit as a cluster head unit; designating the second wireless computing unit and any remaining ones of the plurality of wireless computing units as cluster member units; transmitting data from the first wireless computing unit to the AP for a first predetermined time proportional to the amount of data to be transmitted by the first wireless computing unit; thereafter, re-designating the second wireless computing unit as the cluster head unit; re-designating the first wireless computing unit and any remaining ones of the plurality of wireless computing units as cluster member units; and transmitting data from the second wireless computing unit to the AP for a second predetermined time proportional to the amount of data to be transmitted by the second wireless computing unit.
