Performance Analysis of WSN by varying number of clusters

A Wireless Sensor Network (WSN) consist of huge number of Sensor Nodes (SN’s) which are powered by irreplaceable battery source. So as to get best outcome of WSN, better network lifetime, equal load balancing among all SN’s and scalability of the network among the network are to be taken care off. For getting optimal lifetime from sensor network, clustering is one of the best techniques. Basically it is a process of placing similar kind of nodes together which works parallel with each other. One elected node from a cluster is responsible for transmitting data cluster’s aggregated data to the resource opulence node known as sink or Base Station (BS). An efficient scheme is required for formation of clusters & electing CH for network optimization. This work focuses on analysing network performance by varying number of clusters during the network operation. In the end it checks the lifetime (stable & Overall) of the network by varying probability factor for number of CH’s (Cluster Head) in network. Result analysis shows that lifetime of the network decreases gradually while increasing the probability of CH (Cluster head) however there is not as much difference observed in Stable Lifetime.
