Abstract

In Wireless Sensor network (WSN) the energy consumed by the cluster head and other nodes for communicate to each other. Due to randomness property in cluster head selection, any sensor node can become cluster head and also form uneven sized cluster. The communication in WSN is made between CH and BS for data transfer. A large a number of sensor is effective for gathering the data in Varity of environment and sensed data is gathered and transfer to the base station for further processing to meet end user queries. In large size cluster, member nodes need more energy for data transmission. More number of clusters in sensing field reduces the cluster size as well as energy consumption of cluster members. It can increase data transmission from cluster head to base station (Inter cluster communication) that consumes lot of energy in the larger area network. A homogeneous sensor network consists of identical nodes, while a heterogeneous sensor network consists of two or more types of nodes organized into hierarchical clusters The network characteristics of existing classical clustering protocols for wireless sensor network are homogeneous. Clustering protocols fail to maintain the stability of the system, especially when nodes are heterogeneous. LEACH use Homogenous or heterogeneous sensor network and find the cost complexity .Simulation result using MATLAB are shows that the proposed Leach heterogeneous system significantly reduce energy consumption and increase total lifetime of wireless sensor network but the cost complexity is increases compared to homogenous LEACH protocol this show using some factors like magnitude, phase response, filter Information, round noise spectrum.
