Its growth increases day by day. Sensor node normally senses the physical event from the environment such as temperature, sound, vibration, pressure etc. Sensor nodes are connected with each other through wireless medium such as infrared or radio waves it depends on applications. Each node has its internal memory to store the information regarding the event packets. Basically this whole sensor network called sensor net is working in a distributive manner, sensor nodes are deployed in a huge area and use to send data packet in broadcast manner. This data packet finally reaches to the base station or called sink and vice versa. Nodes are deployed over a huge region in an ad-hoc based manner and use to sense the physical events. If any region cannot be sensed by any nodes then that region is called blind area. If blind area is too large then data retrieval is become un...

Its growth increases day by day. Sensor node normally senses the physical event from the environment such as temperature, sound, vibration, pressure etc. Sensor nodes are connected with each other through wireless medium such as infrared or radio waves it depends on applications. Each node has its internal memory to store the information regarding the event packets. In this paper we will come to know the various algorithms in clustering techniques for wireless sensor networks and discuss them. Clustering is a key technique used to extend the lifetime of a sensor network by reducing energy consumption .It can also increase network scalability. Sensor nodes are considered to be homogeneous since the researches in the feild of WSNs have been evolved but in reality homogeneous sensor networks hardly exist. Here we will discuss some of the impact of heterogeneous sensor networks on WSN and various clustering algorithms used in HWSN.

Routing protocol with energy efficiency has been a challenging issue in the design of wireless sensor networks. Efficiency and security are two topics in the design of routing protocol for WSNs. Heinzelman, ET. Al. introduced a hierarchical clustering algorithm for sensor networks; called Low Energy Adaptive Clustering Hierarchy (LEACH).The new proposed scheme describes two new ways to select Cluster head. Analysis shows that the improved or enhanced LEACH protocol balances the energy expense, saves the node energy and hence prolongs the lifetime of the sensor network.
