Wireless Sensor Network (WSN) is a hot research area due to its use in many military and civilian applications. WSN consists of distributed small, low power and limited capabilities sensors that are scattered in the network field to sense different parameters in the environment. The sensed data will be sent to a more powerful node called sink node (Base Station). The sink node is usually connec...

Wireless Sensor Network (WSN) is a network which formed with a maximum number of sensor nodes which are positioned in an application environment to monitor the physical entities in a target area, for example, temperature monitoring environment, water level, monitoring pressure, and health care, and various military applications. Mostly sensor nodes are equipped with self-supported battery power...

The monitoring of power consumption has become of a great interest in recent years as well as the innovative technologies available to realize Wireless Sensor Networks (WSNs) have experienced a great growth. While smart metering technologies for electric energy are already established, as sensors power supply comes directly from power lines, WSN nodes for gas metering should necessarily be equi...

A Wireless Sensor Network (WSN) is a wireless decentralized structure network consists of many nodes. Nodes can be fixed or mobile. WSN applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in WSN. Wireless Localization used to determine the position of nodes. The precise localization in WSNs is a co...

Environment monitoring is important for the safety of underground coal mine production, and it is also an important application of Wireless Sensor Networks (WSNs). We put forward an integrated environment monitoring system for underground coal mine, which uses the existing Cable Monitoring System (CMS) as the main body and the WSN with multi-parameter monitoring as the supplementary technique. ...

Water supply systems have been facing many challenges in recent decades due to the potential effects of climate change and rapid population growth. Water systems need to expand because of demographic growth. Therefore, evaluating and increasing system capacity is crucial. Specifically, we analyze network capacity as one of the main features of a system. When the network capacity starts to decre...

In this paper we have designed, developed and proposed a prototype Wireless Sensor Network (WSN) System to monitor the Fish Farm. Salinity of the fresh water is a prominent parameter and is responsible for the difference in environment from marine conditions. Salt is an effective ingredient for fishes in fighting disease, parasites and chemical poisoning. The pH is equally a key parameter which...

Abstract Wireless sensor networks (WSN) were cataloged as one of the most important emerging technologies last century and are considered basis Internet Things paradigm. However, an undeniable disadvantage WSN is that resources available for these types networks, such processing capacity, memory, battery, usually in short supply. This limitation implements security mechanisms a difficult task. ...

The main tasks of a Wireless Sensor Network (WSN) are data collection from its nodes and communication of this data to the base station (BS). The protocols used for communication among the WSN nodes and between the WSN and the BS, must consider the resource constraints of nodes, battery energy, computational capabilities and memory. The WSN applications involve unattended operation of the netwo...

In systems experiencing water scarcity and consequent intermittent supply, users often adopt private tanks that collect water during service periods and supply users when the service is not available. The tank may be fed by gravity or by private pumping stations depending on the network pressure level. Once water resources are collected, the tank can supply users by gravity if it is located on ...
