Device Discovery Schemes for Energy-Efficient Cluster Head Rotation in D2D
Abstract: In this paper, novel
device discovery approaches for the cluster head rotation, which is a state-of-the-art
method for the Device-to-Device communication, are proposed. The device
discovery is the process to detect and to include new devices in the
Device-to-Device communication. The proposed device discovery is aimed to
attain energy efficiency for the communication devices. We propose two schemes
for the device discovery: eNB-assisted and independent device discovery.
Compared to previous work, the proposed device discovery is utilizing the
cluster head rotation method, to achieve better energyefficiency. In this work,
several simulations were performed and discussed for both schemes. In the first
simulation, the device energy consumption is examined. After that, the number
of devices that get rejected is studied. The device discovery processes in
multi cluster head scenario, which is cluster head rotation, are examined in
this paper. The result of the simulation shows that eNB-assisted device
discovery can provide better energy efficiency. Also, the number of rejected
devices of the eNB-assisted device discovery is slightly lower than independent
device discovery.
