Abstract: -The wireless sensor network is designed to install the smart network application or network for emergency solution, where human interaction is not possible. WSN consists of many sensors to monitor physical or environmental conditions, such as health state monitoring, military applications, temperature, sound, pressure, motion or pollutants and to cooperatively transfer the data through network to a central location. The main constraint of WSN are low power and minimum processing. The nodes in WSN have to self organize as per the users requirements to monitor environments. The sensor nodes are deployed in an unreachable location for particular mission, it is difficult to exchange or recharge the nodes battery. To increase the lifespan of Wireless Sensor Network, well-organized utilization of power is required. In this paper we introduce a new mechanism to increase life time of the sensor nodes in the network. The proposed work minimizes the length of the packet by processing the data at the node. Furthermore We emphasize on Node state switching mechanism which helps to increase the lifespan of WSN. The proposed method reduces the length of the packet by processing the data at the node itself using Delta Modulation. In the proposed method present data value is compared with the previous data value, and if present data value is greater than the previous data value, output is non zero i.e. 1 otherwise output is ‘0.’ It reduces the size of packet and hence the energy consumption. Sensor represents two states i.e. Active and Ideal. Only small number of sensor nodes is in active state in the covered regions and the remaining are in ideal state. Sensor represents two states i.e. Active and Ideal. WSN sporadically change their status from active to ideal and ideal to active according to network requirement. Time to time communication between entire nodes of a specific region is essential to avoid unexpected network failure. After a fixed time interval ideal state nodes must be in a position to check whether the active nodes are still active or not. Every active node required energy to sense data on the another hand energy of ideal nodes is saved and it will be used only when it gets active.
