Wireless sensor network based monitoring system for precision agriculture in Uzbekistan

Abstract

The last decades the WSN technology has been adopted by more and more scientific fields for accurate and effective monitoring of climate phenomena like air pollution, destruction phenomena like landslides, etc. It has been widely used in agriculture for field monitoring. WSN is an emerging technology, which through the research in the labs and the real deployments has been proved to be a significant and valuable tool for scientists to explore another world which is behind the various environmental phenomena using tiny sensor nodes In this article, "Expert Advisory System" was developed to improve the productivity of farmers, save their time and improve the efficiency of the crops. The system monitors real-time crop fields using wireless sensor networks and provides the necessary information to farmers via the Internet. The farmer will be required to undertake the necessary remedial action on the basis of the information received. It's also provided that the simulation of WSN in Contiki Simulator tool. Moreover, the queing model for WSN to also considered in this work.

A Systematic Review of IoT Solutions for Smart Farming

“…Network topology is another important aspect of an IoT solution. According to [ 61 ] the topology of sensor networks can be star, tree (or cluster) or mesh. The network topology impacts the distance between the sensor nodes and the destination and, consequently, the number of sensor nodes in the WSN [ 190 ].…”

“…Tree (or cluster) networks combine multiple star networks. Both [ 61 ] and [ 178 ] implement a cluster network for monitoring crops. In [ 61 ] sensor nodes collect information from a crop and send messages to a router node.…”

“…Both [ 61 ] and [ 178 ] implement a cluster network for monitoring crops. In [ 61 ] sensor nodes collect information from a crop and send messages to a router node. This router node acts as the gateway of the cluster and retransmits the message to the main router node of the network.…”

IoT-oriented software platform applied to sensors-based farming facility with smartphone farmer app

“…The cluster coordinator node collects data from sensor nodes for 30 min and then sends data packet to the control unit, to then return to the listening phase. Described operation requires an agreement between transmission times of different nodes for avoiding collision between the transmissions towards the same coordinator node; this is obtained by p roperly scheduling the transmission times of nodes for avoiding overlapping [23,24]. The coordinator node has the function to generate the local network to which sensor nodes have to connect and to gather data from WSN nodes within prefixed time interval, sending then them to the control unit installed in the central body of farming facility, according the flowchart modalities of Figure 5(a) [23].…”

Calculating algorithm of service quality statistical parameters for asynchronous network subscribers

“…Currently, most methods for assessing the quality of user service on communication networks used in the design either consider the problem in relation to one-dimensional traffic or do not take into account the influence of a finite number of load sources [11][12][13][14]. This limits methods using in solving design problems of multiservice networks, including in areas of subscriber access networks [15,16].…”
