Ongoing research work shows that homogeneous sensor networks have poor security, connectivity, performance and scalability. Heterogeneous sensor network (HSN) consists of physically different types of sensor nodes. The feasibility of implementing Elliptic Curve Diffe-Helmen (ECDH) in HSN is simulated in this approach. Under dynamic condition of sensor node, implementation of grid-based coordinate route driven scheme has been proposed. This route driven scheme is highly adaptable for public key management scheme for HSN. It also compares the energy and throughput efficiency for dynamic position of sensor nodes. The proposed method is compared with the existing routing techniques like AODV and DSR. The proposed method dramatically increases network lifetime based on the elected coordinator nodes and the size of the grid area.
