Maximizing Network Lifetime of Wireless Sensor Network

Wireless sensor networks are used to extract various information that is used to collect data. It includes a large volume of data so that its performance may get slower and lifetime of the network may get restricted. This paper deals with the aximum usage period of the networks. The modified LEACH protocol is used to which supports the mobility of the node and so extends the lifetime of the network. The network may contain a large number of sensor nodes in which some are the static refers to Cluster Head (CH), and some Mobile Base station (BS). These sensor nodes consequently detect and send the sensed data to the nearest CH, and later this sends to the Mobile Base Station. This leads to efficient extract of information. To display the improvement and reliability this protocol is compared with the fixed node approac
