System and method for reducing congestion in mesh network

A method to reduce congestion in an access control wireless mesh network, the method comprising steps of:

• generating and transmitting, by way of a control circuitry (104) of a system (100), a read request comprising a first initiation signal to each node of the plurality of nodes (102);
• retrieving, by way of each node of the plurality of nodes (102) a node address of each neighbouring node of the one or more neighbouring nodes;
• receiving, by way of the control circuitry (104), in response to the read request, from each node of the plurality of nodes (102), the plurality of credentials associated with the one or more neighboring nodes;
• generating, by way of the control circuitry (104), a node mapping based on the received plurality of credentials;
• determining, by way of the control circuitry (104), based on the node mapping, a hop count and a response time associated with each node of the plurality of nodes (102);
• and
• generating, by way of the control circuitry (104), a routing path for each node of the plurality of nodes (102) based on the node mapping.

A system (100) to reduce congestion in an access control wireless mesh network, the system (100) comprising:

• a plurality of nodes (102) such that each node of the plurality of nodes (102) is coupled to one or more neighbouring nodes, and configured to store a mapping between a plurality of credentials associated with each neighbouring node of the one or more neighbouring nodes;
• wherein each node of the plurality of nodes (102) is configured to:
• (i) receive a health message generated by each neighboring node of the one or more neighboring nodes, wherein the health message comprises a node address and a Received Signal Strength Indicator (RSSI) associated with each neighboring node of the one or more neighboring nodes;
• (ii) match the RSSI associated with the health message with the plurality of credentials stored in each node of the plurality of nodes (102);
• and
• (iii) generate an error signal when the health message is received after an expiration of a predefined time interval;
• and
• control circuitry (104) that is coupled to each of the plurality of nodes (102), and configured to:
• allocate a predefined time slot to each node of the plurality of nodes (102) such that each node of the plurality of nodes (102) communicates with the control circuitry (104) at the predetermined time slot;
• generate a second initiation signal based on the error signal and provide the second initiation signal to the corresponding node of the plurality of nodes (102) such that, in response to the second initiation signal, the corresponding node of the plurality of nodes (102) retrieves the node addresses of each neighbouring node of the one or more neighbouring nodes;
• transmit a read request to each node of the plurality of nodes (102);
• receive, in response to the read request, from each node of the plurality of nodes (102), the plurality of credentials associated with the one or more neighboring nodes;
• generate a node mapping based on the received plurality of credentials;
• allocate an output transmission power to each node of the plurality of nodes (102) based on the generated node mapping;
• and
• generate a routing path for each node of the plurality of nodes (102) based on the node mapping.
