Khalid Ahmad Darabkh, Jumana N. Zomot · 2018
In this article, a new cluster head selection algorithm is proposed which is considered as a major modification of Centralized Energy Efficient Distance (CEED) algorithm, namely, Modified CEED (MOD-CEED). Actually, MOD-CEED balances the energy consumption between all sensor nodes by distributing the workload among them. More specifically, we compute the optimal number of cluster heads in the network based on the energy dissipation model of LEACH algorithm. Furthermore, we introduce an efficient cluster head selection technique by taking into consideration the residual energy of the sensor node and the distance between the sensor node and the Base Station. Our proposed algorithm is evaluated in terms of network lifetime using MATLAB simulator version 8.5. Simulation results summarize that MOD-CEED contributes efficiently in extending the network lifetime. Moreover, it has demonstrated its superiority over CEED and another relevant algorithm, namely, LEACH-DT.
