Maximizing the lifetime of wireless sensor networks with mobile sink in delay tolerant applications project is a 2010 cse project which is implemented in java platform. This project explains about implement a model for effectively use the power consumption at sensor nodes and also increase life time of the sensor networks. In wireless sensor network communication is done though sensor node which will collect information form environment and communicate with other over wireless Tran’s receiver and sent to mobile sink. In this process there is delay in communication with mobile sink. Data is not sent directly to sink they are stored at nodes and send information when mobile sink is at the most favorable location.
