Abstract
This paper presents methods to improve lifetime of the wireless sensor networks (WSN). Wireless sensor networks consisting of several thousands of sensor nodes and few sink nodes. There are three different methods proposed and one method used to increase the lifetime of the WSN. The methods are – rescheduling the network, mutli-hop transmission and deleting the weak node from the network. A multi-channel system is used to create a cellular structure by assigning one frequency channel per cluster. We have used simulator to evaluate sensors energy level in various rounds. The results are studied and analyzed.
