Abstract
A system and method of communicating between nodes in an ad hoc polling based communication infrastructure such as a Bluetooth system. Frames on a link between two nodes are designated as checkpoint frames on which each of the two nodes checks for presence of the other. Based upon factors such as attendance or absence of the checkpoint frames and usage of the link, one or the other node can adjust the node checking intensity and the other node follows suit in accordance with predefined rules. The checkpoint frames can either be periodic or pseudo random.
Claims28
A method of communicating between a first node and a second node in an ad hoc polling based communication infrastructure, the method comprising steps of:
- defining frames for the first and the second nodes, said frames comprising checkpoints;
- checking by the first node one or more of the checkpoints for presence of the second node;
- adjusting a first node checking intensity in response to results of said checking step;
- and
- communicating by transmitting a signal from said first node to said second node in accordance with the adjusted first node checking intensity.
The method of claim 22, wherein the second node passively checks the first node by listening for a packet.
A system comprising a node in an ad hoc polling based communication infrastructure system, the node comprising:
- a transmit unit for transmitting signals to other nodes;
- a receive unit for receiving signals from the other nodes, said received signals comprising results of checking for presence of the other nodes;
- a scheduling unit in communication with the transmit unit and the receive unit;
- a checkpoint information maintenance unit in communication with the transmit unit and the receive unit;
- and
- a checkpoint generation unit which generates checkpoints having a node checking intensity based upon the results of checking for presence of the other nodes.
