Method and system for optimizing communication in a heterogeneous network

A method for optimizing communication in a heterogeneous network, the method comprising:

• broadcasting, by a constrained device, a message to form an association to a plurality of non-constrained devices in the heterogeneous network;
• receiving, by the constrained device, an acknowledgement message to form the association from the plurality of non-constrained devices;
• computing, by the constrained device, association weightages for each of the non-constrained devices based on at least one parameter related to the each of the non-constrained devices;
• selecting one of the non-constrained devices with a highest association weightage among the association weightages;
• transmitting, by the constrained device, an association request to form the association with the selected non-constrained device;
• receiving, by the constrained device, sleep information of the constrained device from the selected non-constrained device, in response to the association request;
• and
• operating, by the constrained device, in a sleep mode or a wake-up mode based on the received sleep information,
• wherein the sleep information is a sleep time of the constrained device that is determined as one of a minimum value of application loads of constrained devices that identify a traffic of the heterogeneous network, or a minimum value of application loads of constrained devices selected for logging the traffic of the heterogeneous network.

A non-constrained device for optimizing communication in a heterogeneous network, the non-constrained device comprising a processor unit configured to:

• form an association with a constrained device, in response to receiving an association request broadcasted by the constrained device;
• determine a sleep time of the constrained device as one of a minimum value of application loads of constrained devices that identify a traffic of the heterogeneous network, or a minimum value of application loads of constrained devices selected for logging the traffic of the heterogeneous network;
• and
• transmit sleep information including the sleep time of the constrained device to the constrained device,
• wherein the processor unit is further configured to send the sleep information using an acknowledgement message, and
• wherein the sleep information is indicated in a sleep field of the acknowledgement message.

A constrained device for optimizing communication in a heterogeneous network, the constrained device comprising a processor unit configured to:

• broadcast a message to form an association to a plurality of non-constrained devices in the heterogeneous network;
• receive an acknowledgement message to form the association from the plurality of non-constrained devices;
• compute association weightages for each the non-constrained devices based on at least one parameter related to the each of the non-constrained devices;
• select one of the non-constrained devices with a highest association weightage among the association weightages;
• transmit an association request to form the association with the non-constrained device;
• receive sleep information of the constrained device from the selected non-constrained device, in response to the association request;
• and
• operate in a sleep mode or a wake-up mode based on the received sleep information,
• wherein the sleep information is a sleep time of the constrained device that is determined as one of a minimum value of application loads of constrained devices that identify a traffic of the heterogeneous network, or a minimum value of application loads of constrained devices selected for logging the traffic of the heterogeneous network as a sleep time of the constrained device.
