Cluster head selection algorithm

Cluster head selection algorithm

In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. ... With respect to energy efficiency, the best known protocols are hierarchical in nature.

How are cluster heads selected?

It involves grouping of sensor nodes into clusters and electing cluster heads (CHs) for all the clusters. ... Fuzzy multiple attribute decision-making (MADM) approach is used to select CHs using three criteria including residual energy, number of neighbors, and the distance from the base station of the nodes.

How do you select a cluster head in LEACH protocol?

In our new algorithm, the selection of CH is based on three factors: residual energy, distance between the CH and sink and the number of neighbor nodes within the cluster range. Thus, elected CH must have at the same time a high residual energy, maximum number of neighbor and finally a low distance to sink.

What is cluster head in wireless sensor networks?

A cluster head is a node that gathers data from the cluster sensors and passes this data to the base stations. Learn more in: Optimizing WSNs for CPS Using Machine Learning Techniques. A node in a cluster that is responsible for collecting data from the sensors in its cluster and relay these data to the Base Station.

What is the head of cluster?

Cluster headaches, which occur in cyclical patterns or cluster periods, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head.

What is LEACH algorithm?

LEACH is a hierarchical protocol in which most nodes transmit to cluster heads, and the cluster heads aggregate and compress the data and forward it to the base station (sink). Each node uses a stochastic algorithm at each round to determine whether it will become a cluster head in this round.

Why do cluster heads lose more energy?

The leader becomes in charge of specific additional tasks like gathering data from all nodes in its cluster and sending them using a longer range communication to a sink. As a consequence, a cluster head exhausts its battery more quickly than regular nodes.

What is Leach C?

LEACH-C is a cluster based protocol in which cluster heads are selected by the base station randomly. All the nodes having the energy above average are eligible to be cluster heads.

What is cluster head in IoT?

Clustering is a proper data collection method in the IoT that selectively reduces energy consumption by forming IoT nodes into clusters. The Cluster Head (CH) can control all Cluster Member (CM) nodes, and all intra-cluster and inter-cluster connections are made through it.

What is cluster in wireless communication?

A cluster is a group of cells in which all available frequencies have been used once and only once. Since the same frequencies can be used in neighboring clusters, interference may become a problem. ... However, to maximize capacity the frequency re-use distance should be kept as low as possible.

What is cluster head node?

A head node is setup to be the launching point for jobs running on the cluster. ... A head node is often nothing more than a simply configured system that is configured to act as a middle point between the actual cluster and the outside network.

What is cluster head in HDFC?

Average HDFC Bank Cluster Head salary in India is ₹ 14.8 Lakhs for employees with experience between 8 years to 20 years. Cluster Head salary at HDFC Bank ranges between ₹ 7.2 Lakhs to ₹ 30 Lakhs. Salary estimates are based on 208 salaries received from various employees of HDFC Bank. Very High Confidence.

What is the role of cluster incharge?

The role manages the physical, financial and human resources at multiple sites within a cluster to meet the service delivery needs of the department's programs and to maximise the efficiency of, and return on, Departmental resources.

What is the graphic tool used for managing clustering?

A cluster manager is usually backend graphical user interface (GUI) or command-line interface (CLI) software that runs on a set of cluster nodes that it manages (in some cases it runs on a different server or cluster of management servers). The cluster manager works together with a cluster management agent.

What is LEACH routing protocol?

LEACH is a routing protocol that organizes the cluster such that the energy is equally divided in all the sensor nodes in the network. In LEACH protocol several clusters are produced of sensor nodes and one node defined as cluster head and act as routing node for all the other nodes in the cluster.

Where is LEACH protocol used?

Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is a TDMA based MAC protocol. The principal aim of this protocol is to improve the lifespan of wireless sensor networks by lowering the energy consumption required to create and maintain Cluster Heads.

What is Pegasis routing protocol?

PEGASIS – Power Efficient Gathering in Sensor Information Systems is one such hierarchical routing protocol which follows a chain based approach and a greedy algorithm. The sensor nodes organize themselves to form a chain. If any node dies in between then the chain is reconstructed to bypass the dead node.
