8. The method of claim 1 , wherein the selecting the relay node device comprises: selecting, as the relay node device, a device among the set of devices, that has been determined to have a smallest traffic arrival rate, a largest traffic size or a largest traffic volume.

9. A non-transitory computer-readable storage device having executable instructions stored thereon that, in response to execution, cause a coordinating device comprising a processor to perform operations, comprising:

identifying one or more devices associated with a same entity as the coordinating device, wherein the coordinating device and the one or more devices are part of a set of devices associated in a personal area network; and

coordinating with the one or more devices to enable a single radio resource connection (RRC) between the set of devices and a base station, and wherein the coordinating comprises:

selecting a relay node device, from among the set of devices, to relay data transmitted from the set of devices during a relay transmission mode, and wherein the data is relayed to the base station using the single RRC;

determining a network energy efficiency of the set of devices based on transmission time, an amount of allocated physical resource block, transmission power, and reception time of one or more devices of the set of devices; and

enabling the relay transmission mode based on the network energy efficiency of the set of devices.

The non-transitory computer-readable storage device of claim 9 , wherein the relay transmission mode is enabled when an amount of additional power consumption and resource caused by transmissions between the relay node device and the set of devices is less than an amount of power conservation resulted from replacing individual receptions of the set of devices with relay node device reception.

13. The non-transitory computer-readable storage device of claim 9 , wherein the relay transmission mode is enabled based on a function of a measure of traffic loading for a number of the one or more devices being less than a defined value.

14. The non-transitory computer-readable storage device of claim 13 , wherein the measure of the traffic loading is associated with a first measure of traffic arrival rate, a second measure of traffic size and a number of the one or more devices.

15. An apparatus, comprising:

a coordinating device comprising a processing device configured to at least:

identify one or more devices associated with a same entity as the coordinating device, wherein the coordinating device and the one or more devices are part of a set of devices associated in a personal area network; and

coordinate with the one or more devices to enable a single radio resource connection (RRC) between the set of devices and a base station, and wherein coordination with the one or more devices comprises:
