Power save mechanisms for dynamic ad-hoc networks
First Claim
1. A method of establishing a wireless ad-hoc network connection between a first node and a second node, the method comprising:
- sending a network connection request from the first node during a first subinterval of a plurality of subintervals of a beacon interval, the first subinterval occupying a first position within the beacon interval;
listening for a network connection request from the second node during a second subinterval of the plurality of subintervals, the second subinterval occupying a second position within the beacon interval; and
changing the second position of the second subinterval for a next beacon interval.

Abstract
Techniques for establishing a dynamic ad-hoc wireless network are disclosed. A node transitions between wake and sleep modes during periods defined as beacon intervals. Before a network connection is established and while it is awake, the node transmits network connection request and also listens for network activity. If a beacon or response message is not detected while the node is listening, the node enters sleep mode and thereby conserves power. The node optionally changes the duration of its detection period and/or the time at which it listens for network activity relative to the start of each beacon interval. Information elements are optionally included with transmitted beacons or response messages.

11. A device adapted to establish a wireless ad-hoc network connection, the device comprising:
-
a transmitter configured to send a first network connection, the first network request being sent during a first subinterval of a plurality of subintervals of a beacon interval, the first subinterval occupying a first position within the beacon interval; a receiver configured to detect a second network connection request, the second network request being detected during a second subinterval of the plurality of subintervals, the second subinterval occupying a second position within the beacon interval; and a controller configured to change the second position of the second subinterval for a next beacon interval. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
