The clustering algorithm is considered as a kind of key technique used to reduce energy consumption. It can help in increasing the stability period and network life time. Routing protocol for efficient energy utilization should be designed for heterogeneous Wireless Sensor Networks (WSNs). The authors purpose Hybrid-DEEC (H-DEEC), a chain and cluster based (hybrid) distributed scheme for efficient energy utilization in WSNs. In H-DEEC, elected Cluster Heads (CHs) communicate the Base Station (BS) through beta elected nodes, by using multi-hopping. They logically divide the network into two parts, on the basis of the residual energy of nodes. The normal nodes with high initial and residual energy will be highly probable to be CHs than the nodes with lesser energy.
