Energy Efficient Scalable Data Routing Protocol for Heterogeneous Clustered WSN

In this paper it is intended to propose energy efficient routing protocol for WSNs. The WSN comprises of countless sensor nodes. Commonly the sensor nodes are put in a far-off region to satisfy the necessities of observing or exploration. All the sensor nodes are battery-worked. The existence of a node relies on the battery. As well as sending the node’s own information it likewise assumes a part of a halfway node by getting and sending the other nodes’ information towards the base station or sink.Various effective events have as of now been made to accomplish this objective, yet at the same time there is a need to chip away at this space for additional upgrades. Network and information connect layers in a sensor node assume an indispensable part in the WSN correspondence. The network layer is utilized for way assurance and the MAC sub-layer of information connect layer controls the channel access and advance or get the information to/from neighbor node or sink. Routing and MAC protocols are utilized for information correspondence in WSNs.
