Abstract
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.

Wireless Sensor Networks (WSN) have recently focused a lot of interest in the research community due their wide range of attractive applications and its important position is promoted rapidly
Under dynamic condition of sensor nodes, uniform grid based coordinate route driven scheme consumed less energy when compare to Ad Hoc On-Demand Distance Vector Routing (AODV) and DSR
The non-uniform grid-based coordinate route driven scheme had consumed less energy when compare to AODV and DSR with respect to dynamic condition of sensor nodes
Summary
Wireless Sensor Networks (WSN) have recently focused a lot of interest in the research community due their wide range of attractive applications and its important position is promoted rapidly. Each sensor node contains a battery-powered embedded processor and a radio, which enables the nodes to self-organize into a network, communicate with each other and exchange data over wireless network links. An important area of research interest is a general architecture for wide area wireless sensor networks that seamlessly integrates homogeneous sensor network and HSN. The main goal of key management in HSN is the establishment of secure links between neighbour sensors at network formation phase. Key establishment protocols are used to set up the shared secrets, but the problem is complicated by the sensor nodes’ limited computational capabilities, battery energy, and available memory.
