Network Lifetime Optimization in Sensor Cloud

Sensor cloud is a new technological development and improvement of numerous dayto day life applications. It is in the form to embed for cloud computing with wireless Sensor network. As wireless no more furnishes with processing, information storage and exploring but it all done by the use of cloud andalso it help to overcome problems like efficiency, lifespan and energy supply. The proposed methodology works on push pull mechanisms to save the node’s energy and to improve the network lifetime. The two way communication from sensor to cloud is made possible along with making nodes in active and sleep mode to preserve the node’s energy and prolong the lifespan of network. Push mechanism is responsible for sending the active nodes data to cloud server and push is operated for two ways communication i.e. user request are executed by communicating with sensor nodes from cloud server and intern sensor network provide the required data to cloud server. The result shows that there is an improvement in saving node energy, less end to end delay and hence prolonging network lifetime.
