Transmission Power Control in Single-hop and Multi-hop Wireless Sensor Networks

1 Transmission Power Control Overview in Single and Multihop Wireless Sensor Networks A major challenge in the deployment of Wireless Sensor Networks (WSN) is to minimize the energy consumption of sensor nodes and extend the life of limited capacity batteries It is that. Power control is one of the key technologies used to conserve energy in wireless sensor networks. In this paper, we provide an effective power control scheme for WSN based on the Telosb platform conforming to the IEEE 802.15.4 standard. Our simulation and numerical results show that the energy used to transmit data packets on a network system using short-haul multi-hop path does not necessarily save energy [1].

The Wireless Sensor Network (WSN) is another data collection technology for Mono's Internet, and it has some of the functions to maintain control over multiple nodes through wireless communication such as multi-hop and self-organization. The WSN system includes a central device that provides wireless connectivity to the wired world and distributed nodes. Each node is equipped with sensors to detect physical phenomena such as light, heat, pressure and so on. The purpose of this network model is the sensing by the common network, the collection and processing of sensor information. The system performs data collection and quantification to process convergence and transport applications.

Wireless sensor network is a special ad hoc network consisting of a number of low cost, low power, multifunction wireless sensor nodes with sensing, wireless communication and computational functions. These sensor nodes communicate over short distances via wireless media and cooperate in common tasks such as environmental monitoring, military monitoring, and industrial process control. The wireless sensor network opens up new opportunities to observe the physical environment around us and interact with it. By doing so, you can collect and collect data that was previously difficult or impossible. Wireless sensor networks provide a new way to provide information from a variety of applications, but extracting data from the sensor network is considered a difficult task, regardless of the nature of the physical environment. Data distribution and collection are two terms used in sensor networks to represent two types of data processing methods.

Several studies implement interfaces to different sensor networks for single or complex applications. The wireless sensor network is designed to monitor and control the physical data of the environmental conditions at the removed location and gathers the data at the principal location and sends the control command to send the result of the remote control Can be achieved. A WSN consists of a number of nodes ranging from several to hundreds and each node can be linked to one or more other nodes. A node can be designed to run one or more different sensors with different functions. You can also design a combination of sensors to achieve complex use or exchange data with another network. The node used for sensing is called a sensor node, and anyone can collect data from other sensor nodes. Therefore, any data sensor node can access all data at a very fast rate at any time.
