Abstract: Systems and methodologies are described that facilitate communication in a wireless network environment. In particular, access points can dynamically adjust transmit power and/or carrier-sensing thresholds to allow multiple access points to communicate concurrently. In aspects, access points exchange node information, including RSSI and node addresses, of nearby nodes. The node information can be utilized to detect hidden nodes and estimate interference levels. Transmit power and/or carrier-sensing thresholds can be modified as a function of distance between source and destination access points, interference from hidden nodes, transmission rates, and/or path loss.

Abstract: The invention is defined by a method for establishing quality of service (QoS) communications in an ad hoc network, comprising: ascertaining a path to a destination device; sending a Request- to-Reserve (RTR) control packet to at least a first intermediate device identified along the path,- receiving a first Reservation Confirm (RC) packet from the at least a first intermediate device in response to the RTR packet, the first RC packet including a schedule; transmitting a second RC packet to the at least a first intermediate device in response to the first RC packet; and corresponding apparatus and computer- readable mediumware also claimed.
