Problems solved by technology

The MU utilizes a maximum power level when transmitting to the AP, regardless of the proximity to the AP, consuming a significant amount of battery power and potentially causing interference with communications between one of the other MUs and a further AP.
However, the ad hoc mode cannot typically support a large number of MUs, and these MUs, while in the ad hoc mode, cannot bridge to the wireless network (e.g., a WLAN) or the Internet, limiting functionality.

Abstract

Described are a system and method for clustering wireless devices in a wireless network. The system comprises a wireless access point and a plurality of wireless computing units grouped into a cluster as a function of a predetermined parameter. The cluster includes a cluster head unit and at least one cluster member unit. The at least one cluster member unit utilizes a first power level when wirelessly communicating with the cluster head unit, and the cluster head unit utilizes a second power level when communicating with the AP.

Description

FIELD OF INVENTION [0001] The invention generally relates to clustering wireless computing devices in a wireless network. BACKGROUND INFORMATION [0002] A conventional wireless network may operate in one of two distinct modes: an infrastructure mode and an ad hoc mode. In the infrastructure mode, a mobile unit (“MU”) transmits wireless signals to other MUs via an access point (“AP”). The MU utilizes a maximum power level when transmitting to the AP, regardless of the proximity to the AP, consuming a significant amount of battery power and potentially causing interference with communications between one of the other MUs and a further AP. In the ad hoc mode, the MU communicates directly with another MU, i.e., without use of the AP. However, the ad hoc mode cannot typically support a large number of MUs, and these MUs, while in the ad hoc mode, cannot bridge to the wireless network (e.g., a WLAN) or the Internet, limiting functionality. Therefore, there is a need for an improved network...
