Network Localization

Wireless sensor network contains very large number of tiny sensors; some nodes with known position are recognized as guide nodes. Other nodes with unknown position are localized by guide nodes. This article uses the combination of fixed and mobile guide nodes in wireless network localization. So nearly 20% of nodes are fixed guide nodes and three nodes are intended as mobile guide nodes. To evaluate the proficiency, the proposed algorithm has been successfully studied and verified through simulation. Low cost, high accuracy, and low power consumption of nodes and complete coverage are the benefits of this approach and long term in localization is the disadvantage of this method.

Energy utilization is an important aspect in any Wireless Sensor Network .The data transmission from various components connected over real-time networks consumes more energy in Wireless Sensor Network. Mainly the task of any network engineer lies in performing an energy efficient, so to reserve the nonrenewable energy supply to sensor nodes. The research convey out effective utilization of energy in wireless sensor networks. It is important to comprise long-term and low-cost monitoring in different WSN application. The network algorithms separated mainly in two parts, first to generate multiple paths and second to switch paths from generated list of paths .Which is implemented as multi-hop-communication so that the battery life of the sensor node may live for long term and low cost of monitoring, which achieve the high lifetime of WSN.

Heat Flows

This paper presents an in-situ wireless sensor network (WSN) for building envelope thermal transmission analysis. The WSN is able to track heat flows in various weather conditions in real-time. The developed system focuses on long-term in-situ building material variation analysis, which cannot be readily achieved using current approaches, especially when the number of measurement hotspots is large. This paper describes the implementation of the proposed system using the heat flow method enabled through an adaptable and low-cost wireless network, validated via a laboratory experiment.

Low Rate

Wireless sensor network (WSN) requires a wireless communication technology which is low in cost, low in power and easy to be implemented. IEEE802.15.4 standard is the standard specially designed for low-rate wireless personal area network (LR-WPAN) and aimed at introducing an unified standard for the low-rate interconnection between different devices used by a person or in a home, focusing on low power consumption, low-rate transmission and low cost. Since LR-WPAN which is defined on the basis of standard IEEE802.15.4 is of great similarity with WSN, it could be used as communication platform for wireless sensor. This paper, based on the analysis of LR-WPAN, puts forward the WSN networking scheme based on IEEE802.15.4.

The meter reader enters the meter reading system to calculate the cost after getting the reading. This work is not only labour-intensive, but also inefficient. In addition, incorrect reading may occur due to human errors. With the development of the wireless communication technology, a wireless communication technology named LoRa for long-distance and low-power-consumption devices appeared. LoRa is a wireless communication technology with long transmission distance, low power consumption, low transmission speed, low complexity and low cost. It is mainly used in automatic control and internet of things. Through the comparison and analysis of several wireless communication technologies, a gas meter reading platform based on LoRa spread spectrum and wireless sensors is proposed. First of all, this paper briefly introduces the LoRa wireless communication technology and machine vision technology. Secondly, it gives a detailed introduction to the overall design of the system which includes system architecture design, information acquisition terminal, image acquisition module and wireless sensor module. Finally, an experiment is carried out in a residential area. The results show that the gas meter reading platform based on LoRa and wireless sensor network has a high practical value.</span>

The Stability

Investigation of the stability of the building is a needed measurement process for all buildings in the cities. Periodic monitoring of the structure for such damage is therefore a key step in rationally planning the maintenance needed to guarantee an adequate level of safety and serviceability. However, in order for the installation of a permanently installed sensing system in buildings to be economically viable, the sensor modules must be wireless to reduce installation costs, must operate with a low power consumption to reduce servicing costs of replacing batteries, and use low cost sensors that can be mass produced such as MEMS sensors.
