Hence, there is high demand to design and implement an energy efficient scheme to prolong the performance parameters. The heterogeneous convergence between FBG sensor network and the Internet constitutes the FBG sensor network of Things which can future expand the network applications range and enhance the condition perception and monitoring capabilities.
DEEC have the same problem as SEP protocol as to punish advanced node badly and need to kept global knowledge of network.
Network Model For the large-scale network, the long distance transmission costs much energy and may result in separate groups of sensors. The H-node decrypts and again encrypts the random number with secret key of Lnode.
Hence, stability and lifetime get affected badly. Cluster key is the key which is shared by node to all other neighbouring node for transmitting the local messages in secure manner. The Group key is the global key that which is shared with all nodes of the network.
But the usage of protocols depends upon the applications of the wireless sensor networks. Thus, the whole network Heterogeneous wireless sensor networks hwsn management be connected.
The paper  explains the usage of hybrid cryptosystems for the encryption and decryption of data instead of symmetric and asymmetric cryptosystems. In the study, CH selection is based on residual energy and relative distance in hierarchical clustering network. But, for the said selection, all the nodes must have global knowledge of the network.
The number of keys stored is proportional to the resources of nodes and. These proposed protocols has the advantages like low communication cost, weak freshness, replay protection, semantic security, etc.
The Base station also provides the ID and corresponding secret points to all the nodes of the network. Hence, a better CH selection approach enhances the performance parameters of the network. However, the metaheuristic approach is a full proof solution for energy efficiency and finding the best for global.
Hence, the nodes must have better internal parameter and better connectivity with nodes and mainly situated in the premises of network. El-Khatib, Private key agreement and secure communication for heterogeneous sensor networks, Journal of Parallel and Distributed Computing 70 8 — The proposed scheme is based on QoS aware mobility architecture to guarantee a certain degree of QoS.
This type of network is referred as heterogeneous WSN and has no longer support to traditional designed clustering protocol, which is based on assumptions of equal energy capability nodes homogeneous WSN.

For example, if a sensor is intruded in an HWSN, other kinds of sensors are affected, and this may cause network congestion, network lifetime reduction, sensing inaccuracy, etc. A popular method is to deploy relay sensors for connecting the separate groups. Pre-deployment protocols is the process of deploying the cryptographic keys before deployment of nodes in the area.
This individual generation of keys by the nodes reduces the key storage space of nodes in network. Thus, energy optimization scheme is also being demanded because it minimizes the death of nodes from WSN. With the counter value node identifies that the message received is from the exact node which is connected to the network.
It is a prime consideration that the node always have data for transfer. Calculation of is 3. This mechanism requires high computation and hence it requires more energy but uses less memory to store key.
A novel scheme of energy-efficient event driven hybrid routing protocol proposed by author in [ 20 ]. With these keys nodes that are external to the network can securely and efficiently establish the keys for their secure communication.
By the generated shared secret key the authentication for each node is provided. This paper is organized into following sections, the section 2 consists of the paper that which was proposed to establish the cryptographic keys in resource efficient manner.
Motivation There are certain issues found in the above-mentioned clustering protocols in terms of faithful CH selection, energy-efficient cluster formation, and network management. Energy Consumption Model Communication section consists of transmitter and receiver; transmitter section of sensor nodes consumes energy to run radio electronics and amplifier circuit.
This protocol works on the principle of LEACH as per random approach, but with the consideration of residual energy and death toll calculation from BS. The Base station of the network provides a secret of the key over the elliptic curve which is used by the node to generate key for communicating with other nodes.
While monitoring these networks has to transmit the gathered information via another node to the head of networks. The CH on behalf of sensing network is responsible to forward collected data directly to BS. HWSN is synonymous to real time sensor system, which is composed with different capability nodes for monitoring different parameters.
This scheme also uses the concept of computing reference energy for cluster round.Heterogeneous wireless sensor network (HWSN) fulfills the requirements of researchers in the design of real life application to resolve the issues of unattended problem.
But, the main constraint faced by researchers is the energy source available with sensor. Heterogeneous Wireless Sensor Networks (HWSN) life-time. But some obstacles interrupted the systems Key management is an area stone service for many security alternatives such as comfort and verification which.
but improves the security level and enables the heterogeneous wireless sensor networks (HWSN) to dynamically grow without influencing any party involved in.
