초록 ▼

A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of the proximity of objects. A central computer accumulates the data produced or received and relayed by each module. One of the modules is operable as a leaf node having a sleep mode to conserve energy and an interactive mode. The central computer can send a message to the leaf node commanding it to stay awake in order to receive subsequent communications.

대표청구항 ▼

1. An adaptive network including a control module and a plurality of interactive modules adaptively communicating with the control module, the adaptive network comprising: at least one of the plurality of modules configured to be operable in a sleep mode and in an interactive mode as a leaf node in the adaptive network and to selectively transmit a first message, indicating that the at least one module has exited the sleep mode, to the control module via communication channels between one or more of the plurality of modules in the adaptive network;said control module configured to receive and implement instructions to transmit a command to the at least one module, in response to receipt of the first message from the at least one module, instructing the at least one module not to revert to sleep mode; andsaid control module configured to, in response to receiving the first message from the at least one module, transmit, to the at least one module, a second message acknowledging receipt of the first message and the command instructing said at least one module not to revert to sleep mode. 2. A method for operating a self-adaptive network including a control module and a plurality of interactive modules adaptively communicating with the control module in which at least one of the plurality of modules is operable in a sleep mode and in an interactive mode as a leaf node in the self-adaptive network, the method comprising: when the at least one module has exited the sleep mode, selectively transmitting a first message, indicating that the at least one module has exited the sleep mode, from said at least one module to the control module via communication channels between one or more of the plurality of modules and the control module;receiving instructions at said control module to transmit a command to the at least one module, in response to receipt of the first message from the at least one module, instructing the at least one module not to revert to sleep mode; andtransmitting from the control module to the at least one module, in response to receipt of the first message from the at least one module, a second message acknowledging receipt of the first message and the command instructing said at least one module not to revert to sleep mode. 3. The self-adaptive network of claim 1, wherein the at least one module, when in the sleep mode, only responds to broadcast signals containing a specific identifier corresponding to the at least one module. 4. The self-adaptive network of claim 1, wherein the at least one module is configured to identify an adjacent module as having a best radio link and store information representing the identified adjacent module prior to entering the sleep mode. 5. The self-adaptive network of claim 4, wherein the at least one module is further configured to re-establish a communication channel with the identified adjacent module, using the stored information, upon awakening from the sleep mode of operation. 6. The method according to claim 2, further comprising: said at least one module operating in the sleep mode only responding to broadcast signals containing a specific identifier corresponding to the at least one module. 7. The method according to claim 2, further comprising: said at least one module operating as the leaf node identifying an adjacent module as having a best radio link and storing information representing the identified adjacent module prior to entering the sleep mode of operation. 8. The method according to claim 7, further comprising: upon awakening from sleep mode, said at least one module attempting to re-establish a communication channel with the identified adjacent module using the stored information prior to attempting to communicate with any other module in the network. 9. The method according to claim 7, further comprising: upon awakening from sleep mode, said at least one module re-establishing a communication channel with the identified adjacent module using the stored information.
