What is throughput in WSN?
The end-to-end network throughput measures the number of packets per second received at the destination. It is considered here as an external measure of the effectiveness of a protocol. (c) Success Rate. The total number of packets received at the destinations verses the total number of packets sent from the source.
How is wireless sensor network throughput calculated?
The throughput of the sensor network is measured by the total number of packets sent to base station, packets sent to cluster head during the network lifetime and cluster head formation.
How is congestion handled in wireless sensor networks?
In a review of related works in the context of wireless sensor networks congestion control is presented. CODA [7] is energy efficient congestion control mechanism designed for WSNs. CODA, detects the congestion by observing the buffer size of sensor nodes and the load of the wireless channel.
What is actuator in wireless sensor network?
In the context of sensor networks, any output device. Actuators allow a WSN node to influence its environment, providing a feedback channel through which its decisions can be enacted. Learn more in: Pervasive Wireless Sensor Networks. A device responsible for moving a physical mechanism.
What do you mean by throughput?
Throughput is the amount of a product or service that a company can produce and deliver to a client within a specified period of time. The term is often used in the context of a company’s rate of production or the speed at which something is processed.
What is throughput in microcontroller?
Throughput refers to how much data can be transferred from one location to another in a given amount of time. It is used to measure the performance of hard drives and RAM, as well as Internet and network connections.
What is latency in WSN?
In traditional WSN, the data dissemination latency by using probabilistic broadcast is O(1/r) [26]. However, in LDC-WSN, the nodes would sleep or wake up periodically. A relay node must wait for the wakeup of its neighbors, and, after that, it can perform the transmission.
How is network congestion calculated?
Ping. One of the fastest ways to check if a network is congested is to use Ping because not only can it detect packet loss, it can also reveal delay in a network i.e. through the round-trip time (RTT).
What causes increase in congestion in WSN?
In WSNs, congestion is caused by the following factors: packet collision, node buffer overflow, transmission channel contention, transmission rate, many-to-one data transmission scheme, and dynamic time variation transmission channel.
What are the differences between sensors and actuators within wireless communications network?
Sensor nodes are usually low-cost, low-power, small devices equipped with limited sensing, data processing and wireless communication capabilities, while actuator nodes typically have stronger computation and communication powers and more energy budget that allows longer battery life [3].
What is a throughput in networking?
In general terms, throughput is the rate of production or the rate at which something is processed. When used in the context of communication networks, such as Ethernet or packet radio, throughput or network throughput is the rate of successful message delivery over a communication channel.
