In recent years, the researchers do lot of research on Wireless Sensor Network (WSN). But the most research going on the prolongation of the lifetime of the WSN and declined the energy consumed by the sensors. There are lots of protocols which are generated for routing in WSN but these have some limitations. In this paper, analyzes the cluster head selection phase of LEACH protocol and presents the improved approach of LEACH i.e. CSLQ (CluSter-head based on Link Quality) that improves the lifetime of the network. In CSLQ the cluster - head is selected on the basis of link quality so that number of packet loss is decreased as compared to the LEACH protocol.
