Metrics details. This paper mainly studies the deployment of wireless sensor network nodes in the warehouse environment monitoring system, discusses the deployment algorithm of wireless sensor network nodes in the warehouse environment, and finds out the node deployment scheme with better network performance through comparison. Wireless sensor network node deployment is the basis of wireless sensor network application in storage environment monitoring system. It affects the performance of the whole network and is the primary problem to be solved in network application. This paper discusses the advantages of wireless sensor network in the monitoring of storage environment, especially the deployment and simulation analysis of sensor nodes in the warehouse environment.

Wireless Sensor Network Architecture and Its Applications

The wireless sensor network architecture is built with nodes that are used to observe the surroundings like temperature, humidity, pressure, position, vibration, sound, etc. These nodes can be used in various real-time applications to perform various tasks like smart detecting, a discovery of neighbor nodes, data processing and storage, data collection, target tracking, monitor and controlling, synchronization, node localization, and effective routing between the base station and nodes. Presently, WSNs are beginning to be organized in an enhanced step. It is not awkward to expect that in 10 to 15 years that the world will be protected with WSNs with entree to them via the Internet. This technology is thrilling with infinite potential for many application areas like medical, environmental, transportation, military, entertainment, homeland defense, crisis management, and also smart spaces.

The study of routing protocols in wireless sensor networks has been addressed to improve the usage of limited network resources. In this paper, we give in detailed survey of flat routing protocols flooding, data centric and forwarding based on network structure in wireless sensor networks, while providing the advantages and disadvantages of each routing protocol. By taking into account several parameters, some of routing protocols in this category will be compared. This paper also highlights the associated problem and application type designated for each protocol. Unable to display preview.

In our data-driven society, innovators and engineers are looking at the Internet of Things IoT as an opportunity to introduce new data collection methods that will dramatically change how organizations learn about their surroundings and respond to threats and changes - and there's at least one new technology that's making an impact. Of course, we're talking about wireless sensor networks, or WSNs: groups of internet-enabled sensors that can be dispersed throughout a target area to provide constant feedback and data on environmental changes across a number of dimensions.

But what people do want to know is whether they should opt for a wired or a wireless system. A quick, straightforward installation is one of the main benefits of wireless sensor systems. Wireless systems could be your only viable option where hard wiring is difficult or impractical, such as in heritage buildings, glass meeting rooms, and other situations where there are construction limitations. For example, while running wires between buildings could be prohibitive, you could easily connect a neighbouring building to the network with wireless devices. That means reduced installation costs, minimal disruption to your workforce and interiors, and a system you can get up and running much sooner. It can be a lengthy process with some necessary downtime, and drilling holes means some areas will need replastering and painting.

Comparison Studies of Hierarchical Cluster-Based Routing Protocols in Wireless Sensor Networks

Wireless Sensor Networks - Technology and Protocols. Wireless Sensor Networks WSNs can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location or sink where the data can be observed and analysed. A sink or base station acts like an interface between users and the network. One can retrieve required information from the network by injecting queries and gathering results from the sink. Typically a wireless sensor network contains hundreds of thousands of sensor nodes.

Wireless Sensor Networks : Introduction , Advantages , Applications and Research Challenges

Wireless Sensor Networks WSNs are formed by a large collection of power-conscious wireless-capable sensors without the support of pre-existing infrastructure, possibly by unplanned deployment. With a sheer number of sensor nodes, their unattended deployment and hostile environment very often preclude reliance on physical configuration or physical topology. It is, therefore, often necessary to depend on the logical topology. Logical topologies govern how a sensor node communicates with other nodes in the network.

Metrics details. For wireless sensor networks WSNs based on ZigBee technology, the network topology plays an important role for improving the energy efficiency and the network lifetime. An appropriate construction method of network topology should be designed for saving the energy of the battery in each network node so as to prolong the lifetime of ZigBee WSNs. In this paper, a novel cluster tree topology construction method based on particle swarm optimization PSO algorithm is proposed. In order to transform the network topology construction problem into an energy consumption optimization problem, an evaluation function reflecting the network energy consumption is designed, and the network topology is mapped into a particle population individual suitable for the PSO algorithm. In order to prolong the network lifetime as long as possible, two network topology reconstruction methods with the PSO algorithm based on fixed and variable energy thresholds are further proposed, respectively.

Nowadays, wireless sensor networks WSNs emerge as an active research area in which challenging topics involve energy consumption, routing algorithms, selection of sensors location according to a given premise, robustness, efficiency, and so forth. Despite the open problems in WSNs, there are already a high number of applications available. In all cases for the design of any application, one of the main objectives is to keep the WSN alive and functional as long as possible. A key factor in this is the way the network is formed. This survey presents most recent formation techniques and mechanisms for the WSNs.
