A Survey of Routing Protocols in Wireless Sensor Network

As per the industries demand& advancement of wireless technology, sensor device are vey useful for that area where human cant be reach. In WSN, sensor node having limitation of transmission, processing, storage and lifetime of network due to low battery power of sensor nodes. However sensor nodes have limitation in power strength and bandwidth. Therefore a new idea is required that increase energy efficiencies and increase the lifetime of the network. Routing protocols are main area where work is required for maximize the life of sensor nodes. In this paper we present a survey of routing protocols of wireless sensor network for energy optimization.
