Communication nodes for use with a wireless ad-hoc communication network
View Patent ↗Communication nodes for use with a wireless ad-hoc communication network are disclosed. In an embodiment of the present invention, the communication node comprises a transducer, which generates a signal in response to an external signal. The ad-hoc network communication is supported in part by static communication nodes, which defined an organized infrastructure network in order to achieve the various functions of the transducers. In another embodiment, the communication node for use with a wireless ad-hoc network does not include a transducer. Such communication nodes are preferred for use with a less structured network with virtually no infrastructure and allow for being used with expanding and contracting networks. Mobile communication nodes mostly support the propagation of signals. However, pseudo-static or static communication nodes are also used in wireless communication ad-hoc networks.

a processor;
a transceiver in communication with the processor for receiving signals and for transmitting signals, the signals transmitted and received via a wireless communication medium;
a transducer, in communication with the processor for sensing a first physical parameter and for providing a first signal, including data, relating to the first physical parameter;
the processor for identifying a received second signal as one destined for the monitoring node and other than destined for the monitoring node, and when the identification is indicative of the second signal being destined for other than the monitoring node, relaying the received second signal via the transceiver, and when the identification is indicative of the second signal being destined for the monitoring node, providing an indication to the receiving party of the received signal;
the processor for generating a third signal for transmission, wherein the third signal includes at least the first signal including data relating to the first physical parameter; and
wherein the monitoring node executes an ad-hoc communications protocol to communicate with at least one other monitoring node to form an ad-hoc network.
2. A monitoring node according to claim 1 , wherein the transducer is a security sensor for sensing security data and for providing a first signal including data relating to the sensed security data.
3. A monitoring node according to claim 2 , including a protocol processor for inserting within the first signal data indicative of the security monitoring node.

7. A monitoring node according to claim 2 , wherein the monitoring node includes a protocol processor for identifying the data indicative of the destination for the security data and for relaying the security data when the identified data indicate that the node is other than a destination for the security data.
8. A monitoring node according to claim 2 , wherein the transducer is a household-type security detector.
9. A monitoring node according to claim 2 , comprising a memory for storing an indication of a transmitted third signal and upon receiving a second signal, performing one of transmitting the second signal when the stored indication indicates that the second signal was other than transmitted from the monitoring node and other than transmitting the second signal when the stored indication indicates that the second signal was transmitted from the monitoring node.
10. A monitoring node according to claim 9 , comprising a clock wherein the time the third signal was first relayed is stored.
11. A monitoring node according to claim 9 , comprising a clock wherein the time the third signal was first relayed is stored and after a predetermined period of time, the time is cleared form the memory.
12. A monitoring node according to claim 1 , including a memory having stored therein data, the data for execution by the processor for implementing a predetermined protocol for identifying a received second signal as relating to previously received second signal or other than previously received second signal.
13. A monitoring node according to claim 1 , wherein the transducer comprises a consumption metering circuit for providing a meter signal indicative of data relating to a metering performed by the consumption metering circuit.
14. A monitoring node according to claim 13 , wherein the processor includes instruction data stored in association therewith for, when executed, transmitting the received second signal when it is both other than previously received and other than destined for the consumption meter.
15. A monitoring node according to claim 13 , wherein the processor comprises circuitry for implementing a predetermined protocol for identifying a consumption meter used as a source of data indicative of consumption metering performed by a consumption metering circuit.
