Programmable network node roles in hierarchical communications network
View Patent ↗The disclosure features a method of creating a communications network. In this method, a first tape node includes a first type of wireless communication interface and a second type of wireless communication interface having a longer range than the first type of wireless communication interface. A second tape node includes the first type of wireless communication interface that is operable to communicate with the first tape node over a wireless communication connection established between the first type of wireless communication interfaces of the first and second tape nodes. Over a wireless communication connection, the first tape node sends programmatic code executable by the first tape node to function as a master tape node with respect to the second tape node.

2. The method of claim 1 , further comprising, by the first tape node: instructing the first and second tape nodes to report their current respective battery levels; and determining whether to designate the second tape node as a master tape node of the first tape node based on the reported current respective battery levels.
3. The method of claim 2 , further comprising, by the first tape node, designating the second tape node as the master tape node based on a determination that the current battery level of the first tape node is below a threshold battery level.
4. The method of claim 2 , further comprising, by the first tape node, designating the second tape node as the master tape node based on a determination that the current battery level of the second tape node is higher than the current battery level of the first tape node.
5. The method of claim 1 , further comprising, by the server system, transmitting programmatic code executable by the second tape node to detect and respond to an event.
6. The method of claim 5 , wherein, based on execution of the programmatic code by the second tape node, performing operations comprising transmitting a wireless communication to an address of a third tape node adhered to an associated parcel in the set, and alerting the master tape node based on a failure of the second tape node to receive a responsive communication from the third tape node.
7. The method of claim 6 , wherein the alerting comprises, by the second tape node, transmitting an alarm packet to the master tape node.
8. The method of claim 1 , further comprising designating, by the second tape node, the first tape node as a master tape node with respect to a third tape node adhered to an associated parcel in the set.
9. The method of claim 8 , wherein each of the second and third tape nodes comprises a respective sensor; and further comprising, by the second and third tape nodes, respectively collecting local parcel condition data and processing the collected local parcel condition data to produce respective processed parcel condition data sets.
10. The method of claim 9 , wherein each of the respective processed parcel condition data sets comprises data values of a respective histogram.
11. The method of claim 9 , further comprising, by the second and third tape nodes, transmitting the respective processed parcel condition data sets to the designated master tape node; and further comprising, by the designated master tape node, processing the processed parcel condition data sets to produce a combined processed data set.
12. The method of claim 11 , wherein the combined processed parcel condition data sets comprises data values of a respective histogram.
13. A communications network, comprising:
a first tape node adhered to a first parcel in a set of associated parcels, the first tape node including a first type of wireless communication interface and a second type of wireless communication interface having a longer range than the first type of wireless communication interface;
a second tape node adhered to a second parcel in the set, the second tape node including the first type of wireless communication interface, wherein the second tape node is operable to communicate with the first tape node over a wireless communication connection established between the first type of wireless communication interfaces of the first and second tape nodes; and
wherein the first tape node is a designated master tape node with respect to the second tape node and the first tape node is operable to transmit programmatic code to configure the second tape node as a master node with respect to the first tape node.
14. A method of creating a hierarchical communications network, comprising:
activating a first tape node and adhering the first tape node to a first parcel in a set of associated parcels, the first tape node comprising a first type of wireless communication interface and a second type of wireless communication interface having a longer range than the first type of wireless communication interface;
activating second and third tape nodes and respectively adhering them to second and third parcels in the set of associated parcels, the second and third tape nodes each comprising the first type of wireless communication interface and a respective sensor, wherein each of the second and third tape nodes is operable to communicate with the first tape node over a wireless communication connection established between the first type of wireless communication interfaces of the first, second, and third tape nodes;
by the first tape node, transmitting to each of the second and third tape nodes programmatic code for detecting and responding to an event.
15. The method of claim 14 , wherein, based on the programmatic code, the second tape node performs operations comprising transmitting a wireless communication to an address of the third tape node, and alerting the first tape node based on a failure of the second tape node to receive a responsive communication from the third tape node.
16. The method of claim 15 , wherein the alerting comprises, by the second tape node, transmitting an alarm packet to the first tape node.
17. The method of claim 14 , further comprising transmitting, by the first tape node, programmatic code instructing the second and third tape nodes to perform operations comprising using their respective sensors to collect local parcel condition data and processing the collected local parcel condition data to produce respective processed parcel condition data sets.
18. The method of claim 17 , further comprising transmitting, by the first tape node, programmatic code enabling the first tape node to perform operations comprising functioning as a master tape node of the second and third tape nodes, and processing the processed parcel condition data sets to produce aggregated processed parcel condition data set.
19. The method of claim 18 , wherein the aggregated processed parcel condition data sets comprise data values of a respective histogram.
