This document summarizes a clustering protocol for heterogeneous wireless sensor networks called Distributed Energy Efficient Clustering (DEEC). DEEC elects cluster heads based on a probability related to each node's residual energy compared to average network energy. Nodes have different probabilities of becoming cluster heads based on their initial and residual energy levels. The network model considers two types of nodes: advanced nodes and normal nodes. Several improved protocols are also described that build upon DEEC, including SDEEC, DDEEC, SBDEEC, SEDEEC, EDDEEC and EDEEC. Conference and journal venues as well as authors of the base article from 2016 are provided.

 Criteria for cluster head election
Cluster-heads are elected by a probability based on the ratio
between residual energy of each node and the average energy of the
network.
The epochs of being cluster-heads for nodes are different
according to their initial and residual energy
 Heterogeneous network model
Two-level heterogeneous networks - the advanced nodes and
normal nodes
