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.
