The primary goal of node clustering is network preprocessing that is used to obtain information and limit energy consumed. To support high adaptability and better accumulation of information data, sensor nodes are often grouped into disconnected, non overlapping batches, groups of nodes called clusters. Clusters design hierarchical WSNs which incorporate adequate performance of finite reserves of sensor nodes and thus enhance network lifetime. In this paper different clustering algorithm are compared having different cluster head selection approach. Our paper presents review of different energy efficient cluster head selection algorithms in WSNs. Keywords- clustering algorithms, cluster head (CH), wireless sensor networks (WSN). __________________________________________________*****_________________________________________________ I. INTRODUCTION Wireless sensor network is a communication technology which used in many applications for transmitting data from source node to destination node. A wireless sensor network consists of collection of thousands of sensing devices called as sensors. The sensor node has ability of sensing the environment as well as transmitting data. The huge number of sensor within a wireless sensor network is distributed to monitor and detect the environmental and physical condition i.e. Sound, vibration, temperature. It may also be used in many application like military, battlefield, monitoring, wild animal monitoring, health care applications and also commercial application such as target tracking etc. The sensor node is made up of the hardware components such as CPU, battery power, memory, ADC, sensing devices. The working procedure for sensor node is as firstly, the environment is sensed, secondly the processing for sending the message is done and lastly communication with the B.S or sink is done. The sensor nodes are simulated by various other algorithm and protocol for properly handling the traffic and delay of data transmission from sensor node to destination node. Thee sensor nodes have limited energy, which has given rise to clustering. Energy efficiency is an important factor to extend the lifetime of sensor node. Architecture of WSN is classified as layered architecture and clustered architecture. In layered architecture the sensor nodes communicates with B.S in i-hops whereas in clustered architecture the sensor nodes are arrange in group called cluster and the member nodes communicate only with their respective cluster head and the cluster head with the B.S. Cluster head acts as a leader for its remaining members performing intra cluster data arrangement, data sending and so on. Cluster head aggregates data from other cluster members and sends to sink as single packet, thus Cluster Head reduces data transmission to base station. Fig1: layered architecture
