The clustering Algorithm is a key technique used to prolong the lifetime of a sensor network by reducing energy consumption. It can prolong the network lifetime and improve scalability. In this paper, we propose a novel hybrid distributed energy-efficient heterogeneous clustered protocol for wireless sensor networks (HDEEHC). The HDEEHC protocol periodically selects cluster heads according to a hybrid of a primary parameter and a secondary parameter. The residual energy and the type of a node is the first parameter in the election of a cluster head, and the proximity to its neighbors or node degree is the second. The nodes which have high initial and residual energy will have more chances to be the cluster-heads than the low-energy nodes. The clustering does not depend on the network topology or size. Finally, the simulation results show that HDEEHC achieves a longer lifetime and more stability than HEED clustering protocols in heterogeneous environments.
