Abstract:

For random distribution of large-scale wireless sensor networks (WSNs), a hexagonal centralized cluster-based multi-hop routing protocol (HCCM) is proposed. The base station divides clusters with the lowest energy consumption by choosing the length of a hexagon, and then optimizes clusters according to the number of nodes in practice. Based on the received energy information, the cluster head and multi-hop transmission path are determined with suitable slots being allotted to transmit data. Simulation results show that compared with the low energy adaptive cluster hierarchy (LEACH) and differential evolution-based routing algorithm (DE_LEACH), this protocol prolongs the network life with fewer packets being received in the small scale network. But in large scale networks, this protocol prolongs the network life by 15% and receives 9.5% more packets compared with the energy-efficient clustering technique(EECT), thus improving the network performance, which verifies that this protocol is suitable for large-scale WSNs.
