Method and system for providing data communication through a cluster head for machine type communication (MTC) based group communication

A method for providing data communication for machine type communication (MTC) devices for multiple base-stations in a wireless communication by a cluster head, the method comprising:

• informing to one or more MTC devices in a cluster a primary base station to which each of the one or more MTC devices is assigned, wherein an activation of the one or more MTC devices is updated to the cluster head by each of the one or more MTC devices;
• requesting for a network resource to the primary base station whenever a transmission is ready for each of the one or more MTC devices;
• requesting for providing a secondary base station to the primary base station, if there is a disruption in communication due to unavailability of network resources;
• shifting the one or more MTC devices from a sub-cluster corresponding to the primary base station to a sub-cluster corresponding to the secondary base station, wherein the shifting occurs when a half of a delay tolerance associated with the one or more MTC devices is over and the one or more MTC devices do not get the network resources associated with the primary base station;
• and
• informing to the one or more MTC devices the secondary base station on which one or more MTC devices corresponding to the sub-cluster is able to shift.

A method for providing data communication for machine type communication (MTC) devices for multiple base-stations in a wireless communication by a first sub-cluster head, the method comprising:

• informing to one or more MTC devices in a cluster a primary base station to which each of the one or more MTC devices is assigned, wherein an activation of the one or more MTC devices is updated to the first sub-cluster head by each of the one or more MTC devices;
• requesting for a network resource to the primary base station whenever a transmission is ready for each of the one or more MTC devices;
• requesting for providing a secondary base station to the primary base station, if there is a disruption in communication due to unavailability of network resources;
• receiving information of the secondary base station from which the first sub-cluster head is able to initiate MTC communication;
• searching for a second sub-cluster head which is linked to the secondary base station in a grouping information;
• shifting the one or more MTC devices from a sub-cluster corresponding to the primary base station to a sub-cluster corresponding to the secondary base station,
• receiving, from the second sub-cluster head, to which sub-cluster the one or more MTC devices is able to shift;
• and
• initiating data traffic transfer from the one or more MTC devices to the secondary base station through a dedicated connection established between the second sub-cluster head and the secondary base station.

A method for providing data communication for machine type communication (MTC) devices in a group-based wireless communication by a cluster head, the method comprising:

• receiving a message from one or more MTC devices for data traffic transfer when the one or more MTC devices are activated, wherein the message comprises a buffer occupancy status of the one or more MTC devices and the cluster head is selected for a cluster comprising the one or more MTC devices which are members of the cluster;
• sending a dedicated connection request with the buffer occupancy status of the one or more MTC devices to a base station;
• establishing a dedicated connection with the base station for transferring the data traffic from the one or more MTC devices to the base station based on availability of one or more network resources for transferring data traffic, wherein the availability of the one or more network resources is determined based on the buffer occupancy status of the one or more MTC devices by the base station;
• and
• transferring the data traffic from the one or more MTC devices to the base station through the dedicated connection established between the cluster head and the base station.
