What is the main source of power consumption in wireless sensor networks?
Moreover, a WSN node typically includes mixed signal processing devices. As anticipated, a well known mixed signal contributor to power consumption is the radio interface, responsible for a large portion of energy consumption.
What is energy efficient clustering?
One of the most suitable approaches to enhance energy efficiency is the clustering scheme, which enhances the performance parameters of WSN. This protocol enhances the energy efficiency of HWSN and hence improves energy remaining in the network, stability, lifetime, and hence throughput.
How can you reduce the power consumption of a wireless sensor network?
In [7], a mobile-sinks-based energy-efficient clustering algorithm (MECA) is proposed for improving the lifetime of WSNs. In this paper, sensor nodes are distributed randomly within a circle, and they can directly send data to the closest mobile sink, to decrease the total energy consumption of WSNs.
Which characteristics of wireless sensor network leads to energy constraint?
The individual nodes in a wireless sensor network (WSN) are inherently resource constrained: they have limited processing speed, storage capacity, and communication bandwidth.
How do you calculate the energy consumption of a wireless sensor network?
Ex, energy consumed when Tx part is turned ON = Supply Voltage (V) * Current consumed for turning on the Tx circuit * time period. The unit is watts-sec or joules. you can use Matlab to calculate energy consumption and wireless sensor network simulation model may be used to calculate the energy.
Which mode consumes the least and the maximum power?
Standby mode
The Standby mode is used to achieve the lowest power consumption.
What is energy efficiency in WSN?
Wireless Sensor Network (WSN) is known to be a highly resource constrained class of network where energy consumption is one of the prime concerns. In this research, a cross layer design methodology was adopted to design an energy efficient routing protocol entitled “Position Responsive Routing Protocol” (PRRP).
What is clustering in WSN?
Clustering is one of the important methods for prolonging the network lifetime in wireless sensor networks (WSNs). It involves grouping of sensor nodes into clusters and electing cluster heads (CHs) for all the clusters. A major challenge in WSNs is to select appropriate cluster heads.
Why would data aggregation techniques contribute to reducing power consumption in a wireless sensor network?
This restriction of low battery power makes the sensor network prone to failure. Data aggregation is very crucial technique in wireless sensor networks. With the help of data aggregation we reduce the energy consumption by eliminating redundancy.
Why energy efficiency is important in WSN routing?
Energy efficient routing protocols are required to minimize the utilization of the power resources and prolonging the network lifetime path while transferring data [4].

What is the role of cluster head in cluster clustering?
In clustering, cluster head(CH) is responsible to send data via other CH nodes to the base station. This tends to create situation known as nodes are die earlier. To increase the node aliveness in the network , energy consumption should be reduced in the network.
What is a WSN sensor cluster head?
Sensors are often deployed densely to satisfy the coverage requirement, which enables certain nodes to enter the sleep mode thereby allowing significant energy savings. The cluster heads can be selected randomly or based on one or more criteria. Selection of cluster head largely affects WSNs lifetime.
How to increase the node aliveness in a cluster?
In clustering, cluster head(CH) is responsible to send data via other CH nodes to the base station. This tends to create situation known as nodes are die earlier. To increase the node aliveness in the network , energy consumption should be reduced in the network.
