Efficient Cluster Heads Selection Based on Index-Modulation in Wireless Sensor Networks

Index-Modulation (IM) has been recently emerged as a promising direction towards improving error performance and spectral efficiency in wireless networks. To this end, IM-based Wireless Sensor Networks (IM-WSN) applied decision gathering scheme clustered Networks, by which significant improvement the rate (DER) is achieved. Later, following same IM principle, efficient IM-WSN (EIM-WSN) introduced, but with emphasis on reducing computational complexity of while performance. Although these schemes cluster heads (CHs) vary dynamically, still they suffer from unfair distribution CH role among nodes. As result, nodes energy will be unequally dissipated, hence network lifetime deteriorated. In study, aiming at balancing nodes, new reporting scheme, namely index-shift, proposed. The proposed analysed terms DER compared previous schemes, EIM-WSN. Analytical simulation results show that demonstrates fair all This, turn, led to extend up 50% other addition acheive better than almost identical
