An improved clustering scheme for EEDC

An improved clustering scheme is proposed for the defeat of producing single-node cluster in EEDC algorithm. In the scheme, a combination of single-hop and multi-hop communication within the cluster is adopted, and the factors of energy, degree, position are considering during election of head node. Simulation results show that compared with EEDC algorithm, the new scheme runs under a more load-balanced network with less single-node clusters and extends the network lifetime more effectively.
