How would you implement smart/low cost flooding in a WSN? How would you know if nodes received the messages?
WSN means wireless sensor network which is basically deployed t gather the measurements from the sensor nodes.there is a control central coordinates with the network and gives the data for processing. The foremost advantage of this is that user can remotely inquire about the presence of water, status of batteries for the nodes, the information about the functionality of the entire system and alarm.the alerts are also communicated using the audible siren to the home of the user.it is considered to be very cost-effective and easily maintained and thus easily accepted by the user.
Most of the sensors are battery powered and it also includes some low power wireless technology. This is considered to be very advanced technology and the use of this technology also increased rapidly in many applications such as home automation, environmental monitoring, health monitoring, etc. Due to this very promising advantages of wireless its eliminating the need for wired connection. The IEEE 802.15.4 standard is particularly suited for the implementation of low cost, low power consumption, reliable control, and real-time monitoring applications. One of the most important factors is low power cost that is why wireless sensors are mostly considered by the user.
The implementation of wireless devices implies the integration of different subjects, such as electronics, computer science, and communication systems. The system connects to the sensors and it then collects the output, processes the information collected and then activates the output.
The proposed sensor is initiative to the telecare and electronic assistive technology, which can help people who have difficulties, due to some disability to live safely.
The deployed WSN is composed of five flood sensors and a gateway or control center.Siren is used to providing an audible warning against water presence. Sensors are basically used because they detect the accumulation of water of the surface and data is sent through the wireless module, which enables communication with the main system. The sensors can communicate with each other using some external network via internet 2G/3G/4G using the control center.The sensors connect to the smart home control center and the user can inquire about the device status by using a phone. If the device detects water, the user gets an alert (usually a text or push notification).Moreover, the sensing nodes also includes the tilt sensor which tells the user if someone moved the sensor and a temperature sensor, a buzzer, and a light.
