Abstract

A system for network topology includes a first edge router node and a plurality of first sensors operatively connected to the first edge router node. A second edge router node is operatively connected to the first edge router node and to the plurality of first sensors. A plurality of second sensors are operatively connected to the second edge router node and to the first edge router node. The first and second edge router nodes are operatively connected to a cloud server through a respective cloud connection, so that in the event of one of the cloud connections becoming unavailable the plurality of first and second sensors in the system can remain operatively connected to the cloud server through the remaining cloud connection.

First claim

What is claimed is:

1 . A system for network topology, comprising:
a first edge router node; a plurality of first sensors operatively connected to the first edge router node; a second edge router node operatively connected to the first edge router node and to the plurality of first sensors; and a plurality of second sensors operatively connected to the second edge router node and to the first edge router node, wherein the first and second edge router nodes are each operatively connected to a cloud server through a respective cloud connection, so that in the event of one of the cloud connections becoming unavailable the plurality of first and second sensors in the system can remain operatively connected to the cloud server through the remaining cloud connection.

2 . The system of claim 1 , wherein communication between sensor and edge router nodes occurs using frequency bands having transmit time limitations.

3 . The system of claim 1 , wherein communication between sensor and edge router nodes occur in frequency bands without transmit time limitations when communication requiring wider bandwidth takes place.

4 . The system of claim 1 , wherein the cloud connections are selected from the group consisting of WiFi, Bluetooth, GPRS and PSTN.

5 . The system of claim 1 , wherein communication between the edge router nodes occurs using frequency bands without transmit time limitations.

6 . The system of claim 1 , wherein the first and second edge router nodes are wall powered having a battery backup power.

7 . The system of claim 1 , wherein the plurality of first and second sensors are battery operated.

8 . The system of claim 1 , further comprising:
a third edge router node operatively connected to at least the first and second edge router nodes; and a plurality of third sensors operatively connected to at least the third edge router node and one other edge router node.

9 . The system of claim 1 , further comprising:
a third edge router node operatively connected to the cloud server and at least one other edge router node; and a plurality of third sensors operatively connected to at least the third edge router node and one other edge router node.

10 . The system of claim 1 , wherein the first edge router node is a main edge router node to the first plurality of sensors and the second edge router node is an alternate edge router node to the first plurality of sensors.

11 . The system of claim 10 , where the second edge router node is a main edge router node to the second plurality of sensors and the first edge router node is an alternate edge router node to the second plurality of sensors.

12 . A system for network topology, comprising:
a plurality of edge router nodes operatively connected to each other, including a first edge router node and a second edge router node wherein at least the first and second edge router nodes are operatively connected to a cloud server; and a plurality of sensors operatively connected to the plurality of edge router nodes, such that a portion of the plurality of sensors are operatively connected to the first and second edge router nodes, wherein at least the first and second edge router nodes have a wireless link to the portion of the plurality of sensors.

13 . The system of claim 12 , wherein communication between sensors and edge routers occurs using frequency bands having transmit time limitations.

14 . The system of claim 12 , wherein communication between sensor and edge router nodes occur in frequency bands without transmit time limitations when communication requiring wider bandwidth takes place.

15 . The system of claim 12 , wherein communication between the edge router nodes occurs using frequency bands without transmit time limitations.

16 . The system of claim 12 , wherein the plurality of edge router nodes are wall powered.

17 . The system of claim 12 , wherein the plurality sensors are battery operated.

18 . The system of claim 12 , wherein each of the sensors are operatively connected to a main and alternate edge router node.

19 . A network topology for a security and access authorization system, comprising:
at least two edge router nodes operatively connected together; at least one sensor operatively connected to the at least two edge router nodes; a cloud server operatively connected to the at least two edge router nodes through a respective cloud connection; and an alarm operatively connected to the cloud server, wherein in the event of one of the cloud connections becoming unavailable the plurality of first and second sensors in the system can remain operatively connected to the cloud server through the remaining cloud connection.

20 . The system of claim 15 , wherein the at least one sensor senses a hazardous condition and communicates the hazardous condition to the alarm through the edge router nodes and the cloud server.
