Abstract
A logical function is executed in addressable units in a wireless local area network based upon the current state value of other units in the network. Depending upon a persistence setting which may be pre-set or programmed into each unit, the logical function may be recomputed at predetermined time intervals, or upon receiving an overriding resetting signal or control packet.
Claims20
A method of operating a wireless area network in which each unit has a state value at any given time, comprising the steps of:
- broadcasting from each unit in the network its network-associated address and state value;
- and
- receiving in each mobile unit in the network the network-associated address and state value of every other unit and computing a predetermined Boolean expression in each respective mobile unit a new state value based upon the received addresses and state values.
A method for providing control signals to network addressable nodes in a wireless area network, comprising the steps of:
- broadcasting an announcement message from each node in the network including a state value corresponding to each respective node;
- receiving the announcement message at each node in the network;
- and
- processing the state value to determine a new state value for each node based upon the state value of at least one other node.
