Clustering is one of the effective technique used to stabilize and extend the network lifetime in wireless sensor network (WSN). Recently, many routing protocols on clustering structure have been designed and proposed for heterogeneous based on network stability and lifetime performance. In fact, early death nodes are one of the key challenges that reflect to the network performance. The aim of this research study is to improve network stability and lifetime period for EDEEC protocol by modify the EDEEC protocol using probability technique in heterogeneous wireless sensor network which is call Hybrid-EDEEC. Hybrid-EDEEC protocol formed from a hybrid method which is by a combination of EDDEEC and IEDDEEC protocols. Dynamically the selection of cluster-heads is based on probability of three-level heterogeneity and probability threshold. The results are analysed and compared with relevant protocols DEEC, DDEEC and EDEEC. As a simulation results shows that the Hybrid-EDEEC protocol has better performance in term of network stability and lifetime performance compared to other protocols.
