A New Approach to Improve Life Time Using Energy Based Routing in Wireless Sensor Network

Wireless sensor network (WSN) consists of many sensors to monitor physical or environmental conditions, such as health condition monitoring, military applications temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass the data through network to a main location. The main characteristics of nodes in Wireless Sensor Network are low power and minimum processing. So it is essential to optimize the consumption of energy in WSN application. The proposed method used existing sleep wake up method to identify the object within the network. That is only few sensors in a network are active and remaining are in sleep state. It retains the energy of node at a particular level. A new routing method implemented in this paper. That is after identifying the object from the network using sleep wake up method, the bandwidth will be increased and send the data to the base station based on the energy level of nodes. Initially routing path selects shortest path algorithm, meanwhile the network calculate the energy of all the sensor and change the routing path from shortest path to energy based path
