The Wireless Sensor Network (WSN) consisting of a large number of sensors are effective for gathering data in a variety of environments. Sensors are usually randomly deployed where battery replacement or recharge is difficult or even impossible to be performed. In this paper, the authors first completely analyze the basic distributed clustering routing protocol LEACH (Low Energy Adaptive Clustering Hierarchy). The classical schemes consider that all nodes are deployed with same amount of energy. Here they consider a heterogeneous medium, i.e. each node is provided with varying power levels called Heterogeneous - Hybrid Energy Efficient Distributed protocol (H-HEED).
