EDCOPA : Enhancing DCOPA Protocol by Exploring New Criteria for Improved Clustering
Foudil Mir, Ahcène Bounceur, Farid Meziane · 2023
The Internet of Things (IoT) has significantly expanded the connectivity of smart devices, emphasizing the crucial importance of clustering for optimizing device energy, particularly in data communication. The DCOPA protocol is presented as a distributed clustering protocol for data communication in IoT based on Wireless Sensor Networks (WSN). The DCOPA protocol uses competition among network nodes, based on the multicriteria aggregation approach. Residual energy and Distance from a Base Station (DistBS) criteria are used to elect Cluster-Heads (CHs). DCOPA operates in two distinct phases: a Setup phase dedicated to CH designation and a Steady-state phase that includes specific periods for normal nodes and CHs. In this article, we propose an enhancement to the DCOPA protocol called EDCOPA, in which we focus on integrating two additional parameters that can influence and optimize the selection of CHs for increased energy efficiency and a better network lifetime. This improvement preserves the distributed and multicriteria aspects of the protocol. The number of times a given node has assumed the role of CH, as well as the energy consumed in the previous round, have been incorporated into the objective function. Simulation results demonstrate that this integration has significantly improved the network’s lifetime and the energy consumption of both nodes and the entire network.
